In a thought jam here . My Trans am , 96 ws6 lt1 , is just fine . But my right foot wants more . Lol I have a brand new ly6 block . And I also have a spare lt1 . As far as build cost .... I've worked up all 3 . Not a whole lot of difference . Since its not a daily driver .. And it currently runs ... This will be a round-to -it build . I know from what I read on the swap to the ls motor is kinda a project . But the power did us nice .

I guess what asking is what is everyone's thoughts ? Is the swap with the extra headache and pretty big cost to do or just stay lt1 base and do the stroker ?

I know greed4 speed is ls guy so that has his vote lol . Was going to start the platinum, gold and dime process (lol)

Any input also welcome

Do u need to smog the car?

The amount of emissions equipment will limit your big inch, big cam efforts. Can u run long tube headers in MO?
Find out how difficult it is to smog before u go big - u maybe wasting your money.

It would be a 383 or 396 lt stroker. Or a ly6 408 stroker .

Emissions are ... GONE !! Lol. It has longtubes on it now . Deleting a/c also and abs . It will be good to go without the smog .
Thanks for the input . If it was an issue that would be something I probably would not have thought of . Thanks .

A simple 383 LT1 with quality components, a strict attention to detail during machining and assembly, and top it off with a heavily ported set of heads.

No need to re wire stuff, its cheaper, and if you are not a full on race car, it will give you just the same grin when you nail it.

That's what I was looking for . I wasn't real gun ho on rewire , new tranny components , new k member ...... There's a shop here that does a lot of the 383s . They have done a all forged one for me in my truck already . So I think I'm just sticking with the lt1 base motor ... Anyone interested in a brand new ly6 block with covers and a few gaskets ? Lol

A 383 is easy... A 396 is almost as easy...just a little more time and money (not much, but some...). And then, like ShowNoMercy said, a good set of heads and carefully selected camshaft and you're having fun...!

Thanks for your input . The 396 is the route I'm going to go . It's not that much more like you said . The heads I'm leaning towards ... After several calls , forum searches and input is the brodix kc ik 210 CBC ported ones . Then a Howard's or crower cam when I get the exact flow numbers .

Without emissions to worry 'bout the sky is the limit. Sounds like u have a sky high spending account too. Just remember its not the price of the parts that make power. It the right combination of parts that make the most power.

Good luck,

Thanks . As far as budget ... I am estemating a 2 yr build . Your right about cost vs the right combo . Trying to do as much research as I can and see what others have had success with and go from there . Rather than throw money at it and think it will be the ticket .

Good night.

Ya know i like the new 3.800" stroke 1 piece seal cranks. They give u correct quench height w/o decking the block - just a shave pass to clean - and u have correct height for great quench with most gaskets - plus adds a few cubes. They're all forged and SCATs are below $700 - half the price of GMPP.

Sorry gott'a run,

Dang ! Could have swore that when I talked to guy at brodix he understood that I said lt1 . See that's what I like . Thanks for pointing that out . Not that I'm ready for them I always like to have a game plan and a list before I start . Much apretiated !

You can convert SBC heads over to LT1 pattern, if you find a really good flowing set of SBC heads that are cheaper than LT1 tricklows/AFR etc heads after converting, could be a valid pick.

Those heads, as far as I know, are not for LT1/4 engine.

EDIT.....SNM beat me to it.

Yep your are correct . I called again and talked to guy I
Was talking to and he didn't realize I was talking about an
Lt1 stroker .
Thanks for looking out !

Ha!

Got it before I deleted it!

Well.....at least the forum was around to keep you from making a BIG mistake

!

Might wanna consider some ported AFR 195's or Ported LT4 heads.

I second the AFR 195 recommendation for a 383. I'd go with 210's on a 396. Oh, wait...I DID...!

Lmao . Well the 210s for me . I'm defiantly doing the 396 . Won't be anytime soon . Lack of mad funds right now plus working on suspension up front . Got upper arms and coil overs left . Then the whole front will be done .
