My question is- did I screw up with 170 runner heads? 190 I next step and better for more hp and volume. It's basically a street fun car- cruising, light to light, very little 1/8 mile drag. I hear sprint?? Cars are capped at 170 runners. 185 is better for more hp and higher rpm. Dyno guy said engine is really peppy. Maybe carb needs tuned better also.
What are your thoughts and opinions? I was hoping for 400-425 hp but maybe the 365 is perfect for a fun town cruiser? Oh- 74 duster that is Stock weight and me~3400-3600 pounds.
