Another LT1 to LS1 swap thread

[LT1B4C]

Is it worth is to Do the swap?

[Fastbird]

Define worth it.

[LT1B4C]

Say you came across the oppertunity to purchase a decent LQ4, say $1200 For complete, now among the other things you need, Is that money worth spending, $ to power wise? for a future goal of ohhh say 500rwhp?

[Fastbird]

For $1200 is could be worth it, but remember that the LQ4 is the truck motor and doesn't carry a high HP rating and has a MUCH lower compression ratio than a stock LS1/6. Would probably be boost friendly though........

[LT1B4C]

Well i've been doing alot of thinking about it, And a built LT, with a shot of Nitro or A supercharger is Fast. It comes down to the "you can make anything run 10's with Money" Situation. My goal is 500RW, and i think an LT stroker with heads and supporting mods fits the bill.

You're going to need a hell of a setup to make 500 RWHP with the LT1/4. MUCH easier with the Gen III/IV stuff for sure.

[LT1B4C]

Eh its not that bad, My friend has a N/A LT 396, AFR ported Heads, Ported Stock intake. All the bolt ons. 12:1 Makes 510 rwhp.

[Fastbird]

How radical of a cam though??? That's what I'm getting at. There's a big difference in what it takes to do that with a LT vs. LS motor.

[LT1B4C]

Yeah i know, Thats with a custom grind, pretty big cam. I know it takes alot less Mod's for power in an LS, Heck i know a few Cam only LS cars around here making 400rw, But Im just saying I would have around 3K In a STOCK LQ/LS swap when I could Use that 3K torward My existing setup.

Please to not tear apart a B4C car to swap in that torqueless feeling LS1

[Camaro_94]

Are you doing all the work yourself on the project, or are you having someone else swap it in??

If your goal is 500hp, then yes... That might not be a bad route to take. If its going to be stockish, then no... very bad decision.

[LT1B4C]

Yes, I would be doing all the work, but I think i might take shane's advice on no tearing apart the B4C. If i were to do it i'd find some V6 donor car.

[Camaro_94]

Why not just start out with a 98-02 LS1 car then?? You can get a pretty clean one for $5000 - $6000 right now.

[Shon Herron]

Having done the swap, I am still up in the air if it is worth it.
For the money I have in it I could have built a mean LT1.
Granted I can make more HP in a more sociable set up but at this point what does that matter (for me).
NOTE, you get a truck motor, you will need the Fbody accessories b/c the truck stuff wont fit under the stock hood of an Fbody.

[ls1dave]

dont do it just for the hp numbers. those numbers are almost an arbitrary number. i find it more useful to chase a time (like 12 flat) rather than a hp number, since all dynos read differently. of course all tracks yield different results too.

I honestly like the LT platform as far as sound feel goes, but the LS is great if you plan to tear up the dynos.
