All this talk is making me crazy. You could easilly dip into the $20k range with that setup, sb2.2 heads and sp but sheesh the power would be nuts.

yea... i mean, you could build a diffrent motor, faster, cheaper..... *cough*LSxorSBC*cough*... but then atleast its a Pesudo-LT1... right?? lol.

If you had the money why even mess with any production any thing? LT1 or LS1.

Honda Hunter

iTrader: (8)

Depends. When you get to that level I dont think there is a cheaper. I guess it would come down to what youre looking for. I'd rather spend the extra 5k and get a LS7 but then again there will be other things needed depending on what its going in. I'd only do LT1 if I'm trying to break records. If I was going DD Id go LSX.

no, for the cost of just that block, i could buy a aftermarket block of the other two motors, and the crank/pistons to go with it... probly not the rods.... or maybe crank/rods but not the pistons.. ect...
its cheaper.. you get my point.


then, i ask this:

if you take a aftermarket block, and mod it to be "LT1 spec"
then you take a aftermarket SBC head, and mod it to be "LT1 spec"
then you take a SBC intake, or a custom intake......


is it still a LT1, or is it just another SBC with reverse cooling added??

i wouldnt.

warhawk and a big turbo... need i say more? lol.

you are 100% correct. why put so much money into an LT1 to make it perform like an LSx when its easier to just use an LSx?
Im tired of LT1s and its just too much money to make them perform as well as an LSx. when heads and cam LS2s can top 500 rwhp and 383 LT1s have trouble topping 425 rwhp, well theres a problem. thats why Im tearing my firebird apart and selling it. I have an LS2 sitting here waiting for a new home. gotta figure out what I want to put it in!


wish I was still in charlestown so I could check out your 3rd gen
did the one dude that was an officer in the navy ever get his turbo f-body done?

That's a good question. Someone alot smarter than me asked the same question in the advanced section on another board. It went a couple of pages.

HAHAHAH taht's retarded..... my 355 made 422RWHP with a 10 minute tune and heads that only flowed 258cfm.....

If your 383 can't make 425 easy then you messed up the combo.... Are LS1's a better motor uhhh yeah... can an LT1 be made to assrape fully built LS1's. certainly......

with stock LT1 castings 383s are restricted. a 355 will dyno close to what a 383 will dyno horsepower-wise. my 383 ran out of breath at ~6200-6400 rpm and i had a pretty well optimized setup. I'd guess with a good dyno tune I would see a hair over 400 rwhp through a stalled 4L60E. A typical LE3 383 behind a t56 with all the supporting components will probably make ~430-440 rwhp after a good dyno tune. that is a good amount of power. what did tony mamo get with a 383 LS1? about 530 rwhp.

it used to be LS1s were too expensive to make good power. now its the other way around. if you want an LT1 to make 500 rwhp you're going to have to spend $3000 on heads and another $1500 converting a single plane over. most people who own LT1s can not afford that kind of build. in LS1 land $1250 will get you a really nice set of ported LS6 heads that exceed 300 cfm and will tickle the 500 rwhp mark with a fast 90/90 combo, which costs less than a converted single plane for an LT1, and a well matched cam.

you should know all this. I can't begin to imagine how much $$$ you have in your setup. it truely looks to be a great car and im glad to see someone with the ***** to make an LT1 fast.

LT1s would get more respect if the aftermarket stepped it up. An LSx-style intake would kick *** but id imagine it would be hard to make with the LT1 intake port layout. I don't see it being impossible though. I want to see 300 cfm off the shelf affordable heads. I'd love to see 500 rwhp LT1s become a semi cost effective reality.

I dont think its gonna happen though

Look at the BBC 409's, when they first came out they were a boat anchor and nobody wanted them. Every one jumped on the 396, 427, 454 bandwagon. Now the 409's are worth so much money. IMO I think in 20 years the LT1's will be the same way. Just give them time.

I see what youre saying but I find it hard to believe for the LT1

See whats under my name It is so much like a 409. The 409 was the best thing since bread and it was gone in a day

Zigroid, I'm afraid you are mistaken about how hard it is to make over 500 rwhp through an A4, with a factory cylinder head and intake LTX. There are more than a couple of them I know about. Just because the guys don't post here, doesn't mean they aren't "out there". They are. No $3000.00 heads, either. Last pull on mine was 522, another customer with a "mail order tune" made 521. Both have non-lock up 4400 converters and 4l60Es. Mine has LT4 heads & intake, his has LT1s. None costs as much as you indicated. A couple others right at 510 rwhp.

I have to agree that the LS1 is certainly a better engine. If I had any sense, that is what I would have built. With mine, I just started out to fix a couple of oil leaks. It kinda snowballed. Nobody has ever acused me of being real bright.

Best of luck, Ed

Its all in the combo, and if you want power you have to do things right.

it was a joke someone made in a thread about putting ls1 heads on an LT1

TwoFast4Lv

iTrader: (8)

Hehe!

Is it the funniest reply I have seen to a "How can I put LS1 heads on my LT1" post and had to save it

BTW thanks for the Help! Worked like a charm

lots of good points in this thread. I'm glad ed wright stepped in, I agree 100% that it doesn't cost anywhere near that much to make an LT1 run fast. They're the best bang for the buck decent car that you can buy (imo the best bang for the buck is a rolling chassis thirdgen but whos counting).

I love LT1 cars. I've owned two of them so far. I owned my first one, sold it and bought an LS1, got tired of that.. it wasn't fast enough, and to make it fast would have broke my wallet in half. sold it for a shitload of money and bought my '97 for less than half the price Guess where all that money is going hahaha

I've got $7k into my car including purchase price (53k miles and an expensive stereo...) and it already outruns that LS1 turd I had before. It couldn't trap better than 103. it was a 99 A4 Z28. Sold for $13,500
