I am building a 69 camaro and will be using an LS1/T56.
I am planning on getting it rebuilt and this is what I would like to get out of it.
400-450 hp, and as much torque as possible.
The car is mini-tubbed with 335-35-17's.
Who would ya'll recomend rebuilding it (around the DFW area)?
What parts should I start rounding up?
Thanks for the help.

If that is flywheel hp, just the bolt-on parts will get you 400, if you need that at the wheels, you need all bolt on parts and a good head and cam package and a good tune of course.

 

All you need is a good flowing exhaust setups, a proper intake setup (dependant upon the setup of the car you put it in), pullies, ported throttle body, that kind of thing. You can get 400 to the wheels with a good cam/tune and well over that to the wheels with heads/cam.

 

400 FWhp .... headers, pulley, ls6 intake.
450 FWhp .... above plus 228 cam.
500 FWhp .... above plus AFR 205 heads...
525 FWhp .... just get a bigger cam.

good luck!

I would go in the dyno section and look at the different setups people have and what their dyno charts look like. These charts usually show rear wheel hp though, and corrected for altitude. I got 430 at the wheels with most of the bolt ons, a mild home port job, stock compression and spark timing, and a fairly large cam. Fuel mixture is 12.8. 430 rwhp is about 485 at the flywheel. You loose about 13% through an M6 tranmision.

 

Thanks for all of the responses.

Yes, I was wanting 400+ at the rear wheels.

 

Good set of headers, and a free flowing exhaust.
Decent cam 230/232 (350.00 with head purchase)
Stage 1.5 rev2 5.3 heads (1550.00)

Ls6 intake and ported TB, tuning
Should get you in the 430+ rwhp range.
With a slightly smaller cam on an engine dyno a junkyard 346 made 540+ HP with our our 5.3 heads.

 

if it's an engine dyno why 540rwhp? kinda misleading since i had to stop and re-read a couple times...haha

 

too much coffee and to fast typing

 

 

take it to FASTech. great group of guys over there. LG can definitely do it as well, they're prolly just a bit more expensive on the install side. either place can tune it for ya!
