ok...i raced my friends 95 t/a t-top with an lt1 and i barely beat it...he tried pulling away from me so i tail gated him and when another lane opened up i slowly passed him... good stuff.

 

riiiight

 

Yup.

What else you got done to the car? What gears?

 

Ya post some real mods..I mean I've got nothing against "lots of stuff painted blue" and "oil pan" but I think you get the drift.

 

whats the diff between z28 springs and regular springs???

 

z28 springs are stiffer cuz of a bigger cam...i have richmond 3.73's and a posi... holley 670 cfm tbi, edelbrock performer rpm manifold...these are not in the sig because i havent updated it since jan... edelbrock headers, catco high flow cat, hypereutectic pistons (block .060 over), block decked to zero clearance, thats all ive added thats not in the sig... and if u dont believe me... i live in des plaines, IL. i'd be glad if u bring a stock lt1 for me to run against.

 

heads are still stock...i mean the castings

 

for some reason I see but I could be wrong, but unless you've changed the cam and heads or done something to them I see

 

whats the Comp ratio u are running...??

and why didnt u just go to a carb...instead of getting another TBI unit?

 

i know the cam is about .450 lift...not exactly sure. i had it in my room for like a year b4 putting it in. i didnt switch to carb or tpi cuz im a moron and didnt think it mattered.

 

The cam swap and spring upgrades are a good boost in the power department, especially if its the xtreme cam I'm thinking of getting. The 3.42 + posi is a major upgrade over the stock 2.73 and 3.23 that the old RS are equipped with. The 670 tbi is a good improvement as well so all in all its up there in the mod department for power leap. It may just as well match against a stock LT1, I'd like to see that one day... actually I'll just do it myself lol.

 

i think somebody's dreaming

either that or his friend doesnt know how to drive an LT1

 

automatic lt1? how can u not know how to drive it? when ur going in a straight line and floor it theres not much too it

 

It's called feathering the throttle not to lose traction. Not sure how his traction was though.

 

sometimes ..people with powerful engines cant drive ...ive raced a guy with a cobra in my v6 ...and to 30mph i had him....all he was doing was spinning in the same place ...the speed limit in that road is 30mph so who cares after it anyways ...

bottom line ..no offense to anyone but most guys (where i live) with LT1/LS1 dont even know what an LT1/LS1 is ...i know another dude with a LS1 camaro...i looked into his hood and told him he has one ..and he goes "duh..is that slower or faster than ur ride"




and camaro71..mark's right ...its not that easy ..auto doesnt mean that u floor it and it'll perform best..u gotta know how to get traction...

 

yup, somebody's dreamin'

 

 

im not gonna argue with a bunch of jackasses on the board. if u have a stock lt1 im in the chicago area and bring it so i can show u i can beat it. those things run 14's... its not that hard for an lo3 to run that.

 

btw...lt1's and ls1's are far different motors. sure they are both 5.7L but different heads/intake/cam/etc. ls1's run 13's stock.

 

So whats your point?

I dont think anybody here said a thing about an LT1 and a LS1 being the same they're completely different motors NOTHING from an LS1 will bolt to a LT1.

 

Yes LT1's run 14's in the 1/4 we all know that,but your tbi 305's not going to pull off low 14's if it's doing the 1/8th mile off the side of cliff ,with just those mods.

 

im quoting myself here ..i said nothing avout the LT1 and LS1 being the same ....if that got missunderstood...

i said guys where i live with such motors dont even know what it is or what the diff is ...

how much hp/Tq is that tbi of urs making ???any idea..

 

before the intake/tbi swap the car made 173.5 hp and 288 ft/lbs at the wheels. dont know about now. i also got the 1"spacer on there. i know what i did...dont believe me its ur problem. i just thought that it was cool a lo3 beat a lt1.

 

must have been one of those v6 lt1's seriously dude, 173 horsepower at the wheels before intake and throttle body, lt1's put down high 2's at the flywheel. i agree with everyone else this is total bull****.

 

like i said...im not gonna argue online. those things are like 235 at the wheels..the lt1's. ok..mine has 173 at the wheels. i got the 3.73's in there from a stock 2.73 which also make me launch faster. but whatever...doesnt matter. believe what u want 2. maybe i'll get a rematch and get it on camera this time.

 

i've personally seen 2 BONE STOCK LT1 formulas run 13's.

What kind of heads are you running...if you're running stock heads and u think you're running low 14's that's downright comical..

 

Hmm....interesting-

Is the Camaro a 5 spd? What's the T/A?
LT1's are good but not impossible to beat.
If the T/As an auto it'll be in the 14's. And probably mid 14s too.

 

the 2 formy's i saw were autos, and i've saw another auto formy pull 14.0-14.1 consistantly, bone stock.

 

my heads have bigger valves, port and polish. both cars are automatics.

 

if you think i'm lying about the port and polish and bigger valves ask to talk to hank at lee auto parts in Des Plaines,IL. he did it. i'll be glad to email any disbelievers his # since evry1 thinks im full of it.

 

i didn't read that part about the headwork, i must've missed it.

what cam are u running, what kind of exhaust?? stock TBI/intake?

 

no not stock. edelbrock performer rpm intake, holley 670 cfm tbi, edelbrock tes headers, catco high flow cat, flowtech warlock muffler, 2.5"piping, i got pictures of the damn motor too so u know im not full of it. just gotta figure out how to post them. i even removed a valve cover so u can see the damn full roller rockers. like i said...cam is somewhere around .450 lift..sont remember cuz i had it for like ayear sitting in my room. i wanted one to pass emissions with. this is with 1.6's, not 1.5's. anymore questions?

 

I think if your car is really puttin out 173.5 hp at the rear wheels u could easily pull past an lt1, then u would wake up and realize that you were thinkin of a grand am not a trans am hahahaha. My car is turnin somewhere around 175 hp and theres no way in hell I could take an lt1. with that kind of hp your lucky to run low 15s. Sorry man but I think your full of

 

My 95 did 14.0 @99 with a 2.2 60' time bone stock. I don't know it might be a clse race if the guy driving the LT1 spun bad.

 

those are damn good times for a stock lt1. seriously tho if you think about it, if you put a L03 as a mid 16 second car, those mods he listed dont really knock 3 seconds off assuming that his friend drives it a half second slower than optimal.

 

Damn, am I the only one here that noticed the 2.02 intake valve quote in his sig???? I was under the impression that 2.02's didn't fit on a 305. HOWEVER, I dont' think he's full of ****, my girlfriends RS has crapier stock heads than him with a 262 extreme energy cam, good gears, headers, exhuast, intake and carb and it takes stock LT1's, even 6 speed LT1's fairly easy..............runs 98MPH in the 1/4, and her RS also has the "LO3" swirl port heads which I guess makes the motor techinically an Lo3 even though its a newer crate motor.

 

yeah but noticed you said CARB, big difference there

 

Silly Silly boys. Let's stop measuring our ***** because I have you all beat!

Seriously though, LT1's are not the fastest thing on the road. I saw a guy with a bone stock L98 with a busted piston(didn't know it until he pulled the engine apart) beat an LT1. I've seen GT mustangs run in the 16's all day.

Here's something that a lot of you aren't considering. THERE WAS A PERSON DRIVING THE OTHER CAR. People are fallable. People who aren't professional drivers are more so than others.

2.02 valves do fit, but it takes a lot of convincing, but less so than usual since the block is .060 over. You're a brave man for going that far on those thin walls. Did you scuff a piston? Good kill and if it means anything I believe you. See you all at SCC this weekend.

 

i havent had any problems with pistons or valves or anything. the .060 over with 2.02 and 1.6's seem to be working good for me. people say im gonna have valve shrouding or something.i talked to my auto shop teacher and he said half the people that say that have no idea what it is. any 1 know?

 

Since the intake valve is so close to the cylinder wall the air does not flow around the whole valve. It only flows around the part that isn't close to a cylinder wall. That turns the 2.02 into about an 1.94, but all intake valves are slightly shrouded.
