So...let's try this.
intake will either be lt1 or hsr
assuming L98 block
weekend toy
no worries about emissions

anyone that has 400+, chime in. let me know your combo's.
danke

 

ive seen 400+ at the wheels with an ls1 along witha cam, home ported and polished ls1 heads, and a custom exuast. My friend knows him and pointed me to his web site. Ill see if i can post a link. It was in a monte carlo, btw.

 

word. i'd like to stay with the L98 or older 350 platform though. i'd rather not drop $5k on just the ls1 itself.
i'd also like to do this N/A

the procharger will come later.

 

Ditch the TPI. You'd be damn lucky to get within 100 HP of that, with that on it.

The more inches the better.

MiniRam or carb are the only ways you're even going to get close N/A. Neither is an option if you have a visual emissions inspection.

 

not really, i saw one for $3500 with computer and T56 trans. I really wish i went that rout rather then bought a 350. In the long run, i probably would have saved money. Now, in addition to needing a carb + dist. to replace my restrictive efi, along with heads, cam kit, and intake, i also need to look into getting another trans to replace my ailing junkyard 700-R4. All those little things (and big things) add up fast. Youll also need to make sure the rest of your car can adiquatly handle the power, that means things like SFC's, suspention mods, upgraded rear end, improved brakes and tires, and a good trans to take the power. Be prepaired to spend some money if you want to make it all work well together.

 

it may be cheap to get the ls1, but parts and mods sure as hell aren't. $400 for a cam?
suspension is taken care of. tranny is taken care of. tires...check. brakes...uhm...stand and pray.

 

Get a Holley Systemax-II kit, ditch the manifold and go with the stealth ram, and there is your 400+ oh and don't forget a good set of headers and ignition system.

 

word...i've thought about that. i wonder how that would like a 400block instead of clean 350?

 

I've seen LS1's going for $3,500.00 or less SHIPPED on ebay. That is complete engine wiring, harness, ecm, tranny, you name it.

LS6 heads go on there all the time for $800.00+, get yourself a 2000 plus ls1 (comes with the ls6 manifold) and some ls6 heads, maybe a cam and you have 400+ at the rear wheels for the price of a halfway decent crate engine. Plus if you really wanted you could sell the tranny for 1000+ and make some of your money back. $5,000 and a lot of your own hard work would put an awesome engine in your car, tons of power, and the fuel economy of a modern ignition and fuel processing system.

Doesn't the z06 get like 22mpg highay and 450hp?

My opinion best way to go.

If you want to spend $5k than go for a 6-71 blower, and strengthen up your engine and tranny a bit. It will give off a lot more power than a LS6, and look a lot cooler too

 

A blower make more power than an LS6? And still get gas mileage? On a stock 350, first off you would blow it up, secondly you might make just over the horsepower an LS6 would, but your engine would not be very reliable at all

 

Must I quote myself?? Try reading that again. I'm 16 but I'm not an idiot. A well planned blower installation can easily produce beyond 450 hp, and it is possible for $5k. I didn't say anything about gas, and I don't believe he said he wanted 22mpg either so a blower system would work.

 

lol ok

If a blower is the answer to everything why isnt everyone on the boards running one?

Strengthen your engine and tranny a bit??? lmao man is that the understatement of the world. To do that, you will need a lot more than $5k. Did you happen to think of the rear end in your equation? or driveshaft? Apparently not.

 

I didn't say it was the answer to everything, I was just simply saying in my own way if he wanted to go through all that stuff to just get 400 rwhp he might as well spend the time to do something cool. I'd say the reason that most people don't switch to a blower setup is the work they'd have to put into it, same reason why most people wouldn't want to buy an engine just to rip it apart and buy more parts for it. What good is two and a half engines going to do him? But I still say just go with something easy like the systemax and hsr.

 

Something cool?

You don't think a Ls1/Ls6 in a thirdgen is cool?

 

I'm not saying the LS6s aren't cool, I'm just saying that a blower is way cooler And its really all his opinion and not mine so its whatever he wants.

 

350ci SBC, blower, headers (1.75" minimum), exhaust, 2x4 carbs, big cam.

Thats basically the best way to get 400rwhp (about 500 crank hp) IMO... most streetable anyway.

 

that is still more streetable to you than a worked over ls6?

Now if your talking the best way to do an easy install, than your right a normal 350 slides right in. Where's the fun in that?

 

I'd go with a 400 small block.

Get a very nice set of heads , either AFR or Pro Lightning maybe 220 cc versions, port em.

Roller cam- your choice,

Holley 750 DP

Performer RPM Air Gap, Weiand Stealth or similar intake.

Run some high compression along with it.

 

All of you have overlooked the absolute EASIEST way to get 400 HP. BIG BLOCK!!!!!! hell you could build a 500 HP big block for under $5000 if you shop around. That is the easiest AND most reliable way to get that kind of power. Plus it will be more streetable than a small block with the same power.

 

Auto or manual?

A manual will be easier then an auto, but can be done. If you have a manual heres what I say

HSR
195 AFRs/TFS
XE276/282 112LSA and accompaning valvetrain
long tubes and full exhaust

Matlock88 almost did it with a similar setup as above with an auto. He used the HSR, 195 AFRs, and XE276 with a tune he got to 380rwhp with some more still there on a SD car. You could also use Topline, but they have controversal flow #s right now and that is why I didnt list them.

 

I'm not sure but if I read right he said he was using his L98 block, so most of the things posted here are void.

 

doesn't really matter which block. preferably something i can find in a junk yard. trying to do the real budget build here.
i can always just freshen up the 305 and throw on a procharger.

tranny is th350

 

about the ls1/6 swaps...anyone got pics?
how is clearance? changing plugs?
