I have been on this board for a while. I am calling in all favors for help. I have a 1995 Z28 with the following. Stage 2 Racenet heads. Racenet ported intake and 58 mm TB. I have 1.6 rockers, new lifters etc. I have the 230 236 on a 111 LSA. Hooker LT's & Borla. I have had the car tuned at the shop I work at in Orlando (Norris Motorsports) with LT1 Edit on the dyno with the wideband. My car is only making 300 HP and 300 TQ with the converter unlocked. So I did a compression test. 220 on every cylinder. So the motor is GREAT!!! The only thing I can come up with why is it so under powered is if the cam was ground wrong. Any opnions would be great and I will answer any questions you have.

THANKS!!!!!!!!!!!!!!!!!!

what size converter


and why didnt you lock the converter.

 

3400 stall I meant I locked it...

 

Anyone please....

 

do you have a scan tool hooked up to it?

I would be more inclined to think the heads were possibly done wrong as opposed to the cam, however its more likely that something just isn't working right in there. Best thinig to do is get a scan tool on it, and run it on the dyno with a Wideband O2 plugged in. These two should tell you everything thats going on inside there.

 

I highly doubt the cam is ground wrong.You should lock the convertor.Any KR?Maybe tuning.
