hello. i'm from finland (europe) and driving a '86 camaro Z28 305tpi automatic. LB9 engine yellow@4500RPM.

building plans (everything else is stock parts):
- Hypereutectic pistones, comp ratio about 10-10.5:1
- Edelbrock High-flo TPI System (intake & runners)
- Edelbrock Performer RPM Camshaft
- Edelbrock tubular exhaust system headers 3" (no catalysator)
- stock but ported cylinder heads with stock valves

but how far will the stock cylinder heads and TPI fuel system let me go? i would like to get a 300HP+ engine after re-build.

give suggestions

thanks!
