Re: My TPI vs. LSX

i wouldn't say they're boats though
my 00 SS weighs in at 3439. take out the spare tire ~3409
That with you in it? I got a feeling my 99 is a pig. it does have a heavy feel to it but i never weighed it.

MPH to weight, the power is the same between these two cars if not more to the cam only car... Differences in the car's chassis works makes all the difference in ET. 9.66 at ony 131mph is an incredible ET for the MPH

That is just proof of how no two cars are the same, getting out of the hole and your setup effect everything else, there are TONS of cars that roll out HAAARRRD out the gate and fall off on the big end, ect.

Re: My TPI vs. LSX

9.6's n/a with a stock shortblock is VERY impressive! he must be spinning the doo-doo out of that thing.

there has been a couple of n/a LT1's running high 9's with 383 cubes and 3300 lbs or something like that. there was only a handfull of guys that actually stuck with the cars over the years. in '98 everyone started jumping ship over to the LS cars, and so did many of the talented racers. the LT1 is the redheaded stepchild. lol

im sure a 358cid LT1 with and SB2.2 topend would run pretty decent.

Sounds like to me a lot of the LSx guy here don't have their stuff together to run those times. Somebody is not doing something right. Different cities, different states, different air and different tracks makes the biggest difference in the way a car runs. In those times you don't know what else was done to the car. In the muscle car era, a lot of those car were stock running in the mid 12's down to low 11's with tire, gear, headers and curve distributors. NOW WHAT? It's all about how you set the car up. I've seen SBC's run in the 11's with old school camel hump heads. You can buy them for less than $500.

It's amazing that a little simple kill story turned into this maddness.

Re: My TPI vs. LSX

It is like this, anything can run good witht he right parts, other engines just run harder, the heads themselves are a one up as everyone knows and a SBC will never be able to spin 7100 RPM like a GEN III/IV stock, or a LT1 wityh cam and single valve springs without allot of money, so that itself throws the LS so far ahead they are a budget king of HP.

So that alone makes allot of people look down on the older engines, i still love the SBC, never had luck with a LT engine, i dont care what you say, the aftermarket for them are lacking, and to me the only thing better than a LS engine is a big block chevy.

As for the old SBC heads, you can port them like any other heads, so they will deliver as well as they can, it is not just peak flow but the mid lift numbers that also do so much to make power, and high port velocity is key at lower lift levels, once again showing what a proper matched combo can do.

Exactly, the NA cars make power off the line and come out swinging so the ET and MPH can look impressive, just showing what a setup can do with the right combo to get it rolling.

Kind of scared to see what kind of a turd my 5.3 will be when the turbo goes on, LOL.

Re: My TPI vs. LSX

what LT1 aftermarket is lacking zones? There are several heads out for it, cam companies have great grinds, heads are plentiful...what is missing again?

Re: My TPI vs. LSX

There is plenty of parts out there for them, but compaired tot he GEN I and III/IV, it is not much.

Not to mention, you cannot look in pretty much every parts catalog there is and find parts for them like the LTx older and newer brother, that is all i am saying.

If it came with a LT1, cool, if you want to swap to a different engine than a whatever or SBC, i cannot justify the LTx platform, they do damn well, but the option for the LTx is out weighed by the LS by a long shot.

Not to mention, i can still score the newer engines all day and not worry about the ignition controller(optispark) giving me fits, there are those that claim BLAH BLAH BLAH that they never have issues witht hem, but guess what, i am not you and i had bad experiences with them and will never look back.

Once again, anything can run well, and i dont mean to dog the LT1, but the LS is just the better option, how many carbed intakes are made for the LTx platform? I mean ACTUAL intakes, not a SBC drilled to work or the heads drilled for the SBC intake. LS is in the game 7 years later with way more of everything, and not to bag on my beloved SBC again, but i hate distributors now that i am spoiled to the LS.

Once you go LS you dont...you can fill in the rest, LOL.

And again, the BBC is still king.

you have lost your mind. the aftermarket for the LT1 blows the LS out of the water. it is a sbc with slightly different heads. sbc can be modified to fit for $400 or less. likewise on the intake manifold. a fast intake for an LS motor is what, $800? there is hundreds of used sbc intakes that can be purchased for $100 and converted for LT1 for $100 or so.
all the sbc stuff works in the bottom end..... hundreds of used billet cranks, rods, pistons..... LS lifters work in the LT....

my sbc dizzy with HVC coil is putting out several times the energy of your LS coils.

Re: My TPI vs. LSX

Since I live in California, I haven't seen a LSX car with all the emission and bolt-on beat my car yet. I like to see that challenge. All those amazing times don't pass smog. If I lived on the east coast I would have a better intake system. So if somebody has a smog legal California LSx, come see me. You got HEADS UP!

How many have you raced?? The bolt on LS1 cars over there would be the same as the bolt on LS1 cars here, and I'm sure that none would have a problem passing emmissions.

Re: My TPI vs. LSX

If any of those guys have LS6 heads swapped on with any small cam that will still pass emissions, they will make close to if not over 400whp without skipping a beat and thats a mid 11 second car with the right suspension/gear/converter.

Re: My TPI vs. LSX

Don't know how many were bolt-ons but two were C5 Z06 and 2 C6 Vettes and about 9 4th gen F-bodies and one 3gen cam and intake. I beat him at the 1/8 track but he pulled on me on the freeway. Also I beat a 2004 Cobra with all bolt-ons(stock S/C with pulleys) from a dig in a quarter only. All this was done with 35hp less than what I have now.

Try reading it again, once again, actual parts for the LTx engine, not modified SBC parts.

The carbed LS intakes are as cheap as 270 new and they can go on EFI can flow way better than the FAST intakes, so dont count that out.

Lets go ***** out, how much can you get out of a actual LTx aftermarket? The LSx is making 510 cubici inches, does the LTx come to 500 cubes with aftermarket support?

Do they make heads that flow 330 out the box for 1000$? How much do they run for a set of new heads that flow over 300? The factory LS block is stronger as well, no need for splayed blocks, no worry of crank snouts breaking off.

I dont like having these conversations honestly, i personally dont like the LTx, but it isnt a bad engine, it just pales in comparrison to its younger brother.

Have you seen the 6 speed N/A record? This is a stroked 6.0 block with heads and what not, with a decent weight, can a LT1 stroked to 396 cubes push that hard? Possibly, bt the engine is older and i have still not seen it done:

8.69 @ 156.00 - 1.26 - Mcleod soft loc --- 402 ---- N/A ------------- 3195 - ls1 joe

EDIT: I forgot to mention, if you run a single coil you have to put out more power due to dwell time being 8x less than a LS engine.

Hahaha, wow you have some terrible drivers out your way. How do you beat 2 C5Z's and 2 C6 vettes along with a pulleyed cobra? All of those cars I can almost guarantee would spank yours pretty good. I could see if you beat one of the vettes because the guy couldn't drive.....but saying you have beaten ALL of those? C'mon man that story doesn't line up.

Then you also only give credit to the cam/intake 3rd gen which is probably the slowest of the cars you mentioned. Not sure if you said it in here but what is your average 1/8 mile time and mph? What do you 60 ft at?

Put it this way, if I get challenge by someone and I accept it then I beat you, who fault is that? Don't bring a knife to a gun fight. I didn't ask them if they could drive or not. The race was on and I won. I'm the one who gets picked on and can back it up. One C5Z Vette was on the freeway the other was o. The street. The C6's Vette was at the track at Bakersfield Raceway. The F-Bodies was both track and freeway. It's not hard to believe since TPI has more Torque from a quick of the throttle. That give me the jump.

what's your best time at the track now? I don't feel like reading through all the bickering to find it. Around the chicago area, a "fast" street car is in the 9s. Our average street cars are in the 10 second range.

My Z28 was refereed, passed smog, is registered, has tags, insured and I drive it about 180 miles weekly. Same with TPITerr.


What’s your best time with your current set up? Not in comparison of past times….


I went 12.4 @114 my first time at the track bogging with 18 inch wheels, 3.08 gears, full audio sound system, dynamited interior, full leather interior(2002 TA Lumbar Seats), A/C components, etc.


I will be at LA Invasion this year in more track friendly attire. (skinnies, weight reduction, fixed clutch hydraulic issues).

We have TpiTerr’s bolt-on LS1 IROC, my mild H/C LS1 Z28, and a bone stock C5Z06 in our driveway if you want to back up your claims.


Grab a lane, I'll give you the hit in my Z28 or the vette!!!!

7.87@90mph 1/8mi. On new combo broke the trans last year and haven't been back yet.
Most cars here mid 12's down to high 11's but a lot of 13 second cars. Things are different here.

Re: My TPI vs. LSX

I'm not trying to be a bench racer here, but you have all that stuff done in your sig, and you're putting out around 380hp at the wheels...considering I have raced a C5 Z06 on the highway before, and know that it is mostly stock with headers and exhaust, and barely inched away from him and my car dyno'd 420hp at the wheels, I find your story a bit of fish tale.

got a buddy with a big cube nitrous LSX that would have gone bbc had he not wanted to get the nitrous LS record. he could have a 600"+ bbc for what he has tied up in the LS. i guess what im getting at there is, if you are going to go big cubes and are buying a $2500 block, might as well make it a bbc.

all the out of the box LT1 heads are 21-23 degree. wont hang with the LS heads, but i will say my stock ported heads flow 295 with a 200cc port.
BUT YOU CAN PUT SOME SB2.2 HEADS ON AN LT1 AND GET 400 CFM.
i know you said that doesnt count, but the retrofit is pretty dang simple.


Have you seen the 6 speed N/A record? This is a stroked 6.0 block with heads and what not, with a decent weight, can a LT1 stroked to 396 cubes push that hard? Possibly, bt the engine is older and i have still not seen it done:

LT1 with 18 degree or SB2.2's would do it. but nobody has.


EDIT: I forgot to mention, if you run a single coil you have to put out more power due to dwell time being 8x less than a LS engine.
does an LS coil take 8x longer to charge than an hvc?

110mph is not going to hang with a pullied Cobra or bolt-on C5Z06 on a highway run.
Both run 7.4-7.5's in the 1/8 mile and trap 116-118 in the 1/4 mile.

I think your (heads, cam, intake, & full bolt-on TPI) will be a good run against TPITERR's(cold air intake/exhaust LS1) He went 8.0@92 on a soft launch before breaking his 10 bolt.

Re: My TPI vs. LSX

you can build 500ci sbc with a brodix or dart block. SBC with CFE topend will put any LSx car on the trailer. fastest turbo sbc runs 5.90s@240.
An LTx is basically a sbc so anything sbc will bolt on,some of which will smash a LSx , I know not fair. An LSx is a cleveland knock off based on a sbc.Some of the highend LSx engines are mimmicking SB2.2 cylinderheads.

SBC > lsx

Re: My TPI vs. LSX

i think alot depends on budget. for my budget, i cannot run as fast as i'm going with a sbc. if i ever do an all out, no holds bar'd, it'll be a BBC.

Zone you said a sbc wont spin as well as a LS motor factory right at 7100? Well here is a sbc that is old as hell and spins just a little above 7100 with factory everything!!!!! There goes that argument hehe

Put it this way, if GM would have invested more time in developing a more streetable 18 deg head port shape and cammed to match, instead of the 18 deg race style heads they made for NASCAR and other racing areas, there would be no "ls" craze. It would still be sbc. GM hired ex-ford engineers who took what they know and made a modern cleveland and it worked out. I believe its the same way Mopar made the new hemi, which shares alot in common with the lsx motors.

The main caps on the block however were a good idea. Do add good strength but doesnt take a ford engineer to know that. But times have changed and the need for new designs was more than long overdue.

Re: My TPI vs. LSX

but i will say my stock ported heads flow 295 with a 200cc port.
AT what lift, whos heads?


on the lsx thing there are mild Lsx stock displacemen cars runing around that truly pass ca smog and are deep in the 11s, no TPI car is going to do that without really tossing some coin at it. Like the Gen1s too but nothing compares to the LSx its the sbc of the future and from what I understand GM is coming out with a NEW gen LSx that makes these dated.

Which is a good thing I think, they should get cheap..for us!

What parts do you think are in it? The best GM has produced and a 3 inch stroke and i bet a pay check it doesnt have single springs like i mentioned. That is also a mechanichal cam if i remember correct. That is a factory race engine honestly.

But that does show Ford how a 302 is supposed to run!!!LOL

all the out of the box LT1 heads are 21-23 degree. wont hang with the LS heads, but i will say my stock ported heads flow 295 with a 200cc port.
BUT YOU CAN PUT SOME SB2.2 HEADS ON AN LT1 AND GET 400 CFM.
i know you said that doesnt count, but the retrofit is pretty dang simple.



LT1 with 18 degree or SB2.2's would do it. but nobody has.



does an LS coil take 8x longer to charge than an hvc?

By all means! The BBc is still the top dog!

As for guys like me, a 700$ 6.0 is the ticket to smoking all the other engines as well as my budget allows, a used cam, new PRs and single valve springs and i am spinning over 7000 RPM with a cheap intake and a ignition controller that does everything you could want for a street car, you just cannot do that with a SBC or LTx, and that is why i back my LS platform, the older engines are great, but i and many others have our good reason for the newer engines to claim king of the small block, especially on a budget.

The LS coils charge just as fast but they dont struggle at all to power a V8 at XXXX RPM like a single coil, it can be done with a GEN I or II as well, and the one popular conversion for the LTx is a 4 coul system and is a waste spark system, making it 4x better than the single.

Never seen a cleveland run like a Ls with a budget, LOL.

Amen, and that is why i stand where i do with the GEN III/IV.

Re: My TPI vs. LSX

if vincent really smoked a c6, or a c5z he would've posted a "my tpi vs lsx vette" ..a while back when it happened. it couldve been a wack driver.. but it shouldve been the right driver.

are you directly talking about ls powered 4th gens or the ls powered 3rd crowd.?.. because there are alot of people on ls1tech in so cal who build a budget street car and pass the sniffer..

on top of my head a basic ls h/c build. untouched AFR heads with carb eo #s, a 224 cam on a 114LSA making 420rwhp though manifolds and "smog legal"
heres another one..even more basic.
Pat G custom Cam spec of 218/230 .595"/.600" on a 115LSA +4 advance.
stock ls1 block, 243 heads(unported and unmilled), Comp 918 springs, factory LS6 intake making 403rwhp/392rwtq though manifolds

you apparently haven't ran into these cars..
you can do it to any car at that same budget range. mustang 5.0s, 240s rx7s, etc etc *definitely lighter cars

now if you guys are directing it to the so cal lsx thirdgen guys..
then it appears to be an insult to the so cal tpi guys. its obvious.
shows what type of crowd other states don't have deal with.

p.s. the king of the hill so cal tpi 11/27/10 doesn't even brag about his numbers on here.

there is a crowd of gm enthusiast that dont really wanna build what you guys call a "CA smog legal street car" these are typically cars with heads, bigger cam, better intake, headers, off road y pipe and exhaust. normal : in every other state. Anyone with the right skills can also build a set of headers and add air provisions. technically approved in CA? not really.. idk about you guys but im not a fan of (CARB) emissions

Re: My TPI vs. LSX

but what is the fastest N/A sbc time?
stock sbc, stock parts sbc or unlimited?

unlimited, there are symmetrical port head fabricated intake setups making over 1000hp n/a on 358" motors. I think the comp/prostock type motors have gone low low 7's n/a in race cars. i've heard 398 ci going 7.07 at 192 in a door slammer

Looks like you beat a C6 that trapped 104mph
Regardless, pretty cool video to see a 3rd gen beat a Vette


Regarding the comparisons between LSx engine and all-out SBC and BBC race only engines, I'll give a slight/temporary advantage to SBC & BBC.

Only because SBC/BBC have been in R&D much longer than LSx platforms. I think this will be changing soon with shops pushing the LSx to new boundaries. LMR's 1800 rwhp Texas mile car going up against exotic TT Gallardos.

http://www.youtube.com/watch?v=ki1QrCGfntk

Any SBC/BBC competing in standing mile competitions or just 1/4 mile?

The appeal of the LSx is easy to make high hp along with reliability, great street manners, mpg etc. Show me a SBC/BBC that can put down 1500rwhp with the same ammenities as LMR's TT Vette (street driven)....

i raced one with a exhaust only L98 at the track and lost by a car and a half. he trapped 106 and ran 13.6's or so to my 13.89 at 97 Not everyone can drive

Just look up Nelson Racing Engines....

Another example, Eric Yost's 80's firebird ran a mile before but not a competitor in that event as its a drag car. He runs mid high 7's in the 1/4 mile with a turbo sbc. I think he went 220's in the mile and thats probably not an optimized setup to run those events. Theres an article on that somewhere i'll have to find.

BBC i dont want to know what they will do in the mile. There are guys with 3600hp setups street driven in the high 6's in the 1/4 mile at over 205mph.... show me a streetable LSx that will do that. Those 1800whp creations by LMR i would think have the power to run extreme 1/4 mile times but then again I dont know for sure. The fastest turbo LSx's i've seen lately are ony low mid 7's using the ERL super blocks.

When it comes to boosted setups, big blocks are king, and sbc/lsx are close to the same level when built right.

FYI, according to LMR...."The awesome thing is that she was very rich (9.8:1) and that was only 28 pounds of boost. I still have about an estimated 8 psi left and the nitrous"


Not taking anything away from the Sledgehammer, its a Chevy/Lingenfelter Icon but at 800hp it would be @ about 200mph in the standing mile.



These BBC really need to step up to the big dogs and prove themselves in the standing mile competitions.

Re: My TPI vs. LSX

I'm curious what actual drivetrain losses would be on something in the 2000 hp range. I want to say I doubt you'd loose over 500 hp from 2300 to 1800whp.... that just seems like an incredible drop. Its common to see 15-18% on 400-500 hp vehicles but 2300 is a different game. I dont think the same % can be applied... if so that be 1955 whp
