430-435 CHP now.....What can I do to get 500-510 CHP? - ZR-1 Net Registry Forums

Right now I'm 382 hp to the rear at 7,000 RPM...

Headers, exhaust , Chip,ported plenum , air horn and I/Hs ..
What can I do to bring this 91 to the 500-510 CHP?

I'm located in NY....Sent Pete an email this morning asking for his advice
since he did my porting..I know port matching the heads will give me more power, yet I don't do that type of work....

Any idea of the cost this might be to accomplish 500-510 horsepower at the crank ? I know Marc has a 510 package but my car is already modded with what I described above...

I was thinking of going to Vette Drs and picking there brain...
I heard stories that were good and bad about the place...

As far as labor, would it be easier to do head work by taking the entire motor out to get to the heads or,just breaking down the motor while its in the car?
