crash_2365

Ok, so first off, I'm new to american muscle, I was a subaru guy for the last few years . I'm currently attending school at wyotech in PA, and I picked up a 97 z28 m6 in trade for my dakota. It already has an SLP intake and exhaust, some mystery injectors, and maybe tuning. I love the car but now that I'm in hi-po, I'm taking the chance to modify it a little bit.

My current build is:

New opti/tune up
Headers
LE2 Heads
cc503
Comp pushrods/lifters/rockers
Tuning
Ported intake mani
58mm tb

I've checked my afr's and fuel trim and the "mystery" injectors are providing plenty of fuel.

My question comes from some dyno runs I made today. I made 3 runs at 294hp/ 330ftlbs. It was done on a dynojet at room temperature. We also ran 3 other cars, and they made about what we expected (04 GTO, 300hp/310ftlbs-ish). Now to me, this seems high for a mostly stock car, so I wanted to know what everybody else thought. It is a 97, so I was wondering if chevy did the ol' mix and match with parts. Any input on my build or the dyno runs?

Sounds like you got a slow car for the mods. Mine made 415rwhp but with a custom cam on a dyno jet.

i would think a cc503 and decent heads should be good for ~350+ rwhp.

Let me correct myself, as of today, the car just has SLP intake/exhaust, mystery injectors, and maybe a tune, but I doubt it. Everything else is what is going in in the next 3 months.

^ what he said... 294 is pretty decent for just an exhaust and intake

CC503 is pretty small
Get a custom grind will make closer to 400 HP with the LE2 heads
