So i started this thread because i have become ill with wanting a LS based engine as i am done dealing with my 305 TPI (had a fire burned the engine harness to many shorts). So i decided to finally focus on the future of the car as it was a gift from my dad and i will never part with it i have a 87 Z28 camaro. i have done pretty much all the mods suspension, brakes, rear end except engine besides minor upgrades so i got a good base. well any ways back to the subject i can bought a 2002 LQ4 short block and some 317 heads but i am a little lost on what to do from here as far as Cam'
I want driveabilty and speedup pretty quick nothing crazy so maybe 400 HP/TQ will be able to do it for me?
Also what PCM Should i use with the ls1 harness?
will the Will the LS1 T56 bolt up no problem?
sorry if all these questions have already been asked and answered I did do a search and didnt really find what i needed

so this i what i got now:
LQ4 Short Block with 317 Heads
Complete LS6 intake(fuel rail,TB,MAFS)
LS1 engine harness
LS1 front accessories No Ac
UMI engine Mounts
Hawks LSX Conversion Headers

Z06 cam should wake it up. Get a 0411 ecu Or you can just get it out of a truck of that year motor. Make sure you address the wiring gremlins because it will be a bitch every time you blow something.

Thanks for your input
what will i need to change to adapt the Z06 cam? what kind of numbers will i see at the crank?

Just to answer a few questions. A t56 will bolt up no problem and for a street clutch the ls7 clutch is nice but if you plan on drag racing at the track more often..go with something a bit beefier like a monster stage 2 or equivalent. I just opted to switch to a 411 pcm since its a faster processor and had slight os differences that made fine tuning my setup easier.

Ill chime in a little to give you an idea what kind of power I made with my Lq4. I started with 100%stock lq4 with 317 heads and had put in my 228r cam.At that time I was running stock fbody manifolds and after tuning the car put down 320whp/330tq.Driveability was like stock ls1..after tweaking the tune a few times.It was quick..but left me wanting more.Last year I got a pair of 243 heads and had them milled .030 and used stock head gasket.With no other changes I hit the dyno and put down 370whp/380tq. Thats when the car felt like something and i know that these motors like compression.Midrange and topend power was strong.From 3000-6700 the car just pulls and pulls.The past 2 months i went with the cheapy 1 5/8 longtube headers and did an 3" e-cutout.hit the dyno again for a slight retune and I hit 400whp/400tq on the dot.And still drives like when i had my stock ls1 swapped car but with a punch.I have stock ls6 intake..injectors..nothing crazy by any means.there are alot better choices for cam now that will give you power without being harsh on the drivetrain.Id want to go to a Tick performance cam as im seeing alot of nice setups from them lately.
