How much from heads / cam I know everyone hates these threads but I cant help myself
2001 M6 Firebird
Mods before H/C
Pacesetter LTs
TSP ORY w/ Moroso SpiralFlows and dumped
Fast 92/92
SLP lid
Walboro 255 and SVO #42
With a tune the car put down 341/354 through an S60 w/ 4.10s
New mods
PRC 2.5 5.3 (unmilled w/ stock head gaskets)
227/231 .613/.619 113+4
and supporting mods
Any guesses? Thanks

nah the S60 , 4.10s, and the rims kill the dyno numbers. Just got back it put down 408 rwhp / 387 rwtq. Still need to do an underdrive and Im going to change the exhaust setup which may or may not help but its mostly for sounds/looks improvement.

Rearend would eat some power and big 18s for sure also. Like former guy said was this a mustang dyno?
Still a couple tricks to try. Underdrive pulley and cutout. Might be some left in the tuning as well. To tell the truth not that impressed with those heads compard to say some afr or trick flows. Likely find an easy 20 or 30 more hp with either of those heads but of course they are a lot more money.

Waiting on the new exaust to show up. Have an ASP 25% UD ready to go. Also have the stuff for a LS6 PCV conversion ready to go as well. Would an extremely crappy functioning PCV system lower the HP numbers? Im getting a good bit of oil into the intake etc.

Exhaust cutout is cheap mod. Electric cutout are big fun.
Underdrive should give a few more hp. That oil in the intake isn't going to do that much unless its super bad might cause some knock maybe and that could hurt power. STill you have 18 inch rims and the s60 does take some power over say a stock 10 bolt. I think you are doing pretty good for what you have.
