is 340whp reasonable? Im asking this for a friend of mine.
His car is a 95 Camaro M6 with the following mods
cc306,ported heads & intake,shorties,58mmTB,CAI.
He dyno tuned it & the car made 340whp only
is this normal?
Thanx

[QUOTE=ss.slp.ls1;10846654]Definitely add some LT headers, CC 1.6 Promagnum NSA rr's, TF guideplates, and a nice catback or an electric cutout before the axle.
Doing all of the above will probably net you an additional 25 rwhp![
Wow 25 more whp for just doing that? what else do you suggest to get more HP out of this thing?

[QUOTE=scorpion_z28;10846835] I wouldn't say "just" that, those are some major changes. But yes, I would think you have a lot left on the table with your current set up.

Better porting, an electric waterpump, Longtubes, 1.6RR's, and better springs. I'm really surprised that he got the heads and cam done, yet didn't do all the important stuff when the heads are off like bigger valves/1.6RR's/hardened pushrods/LS7 lifters/and beehive springs.

The problem is more than likely that cam. Even with head work it is absolutely enormous on stock heads, even after some port work. Extensive port work is required. Your 58mm throttle body isn't giving you a gain. And I would not finger out the shorties as your primary concern. I would estimate something is not functioning properly, or your tune is not a good one. Some of the others are suggesting to do more bolt on's, i would hold off until you figure out your current issue(s). your car should be making more, no one can argue that...
