I need to build an engine. My 289 has been rebuilt three times and has 300K + on it. I want to buy a good 302 roller block to start the build. I use my car as a daily driver and the engine will sit in front of a T5Z and 3:55 gears. I will autocross a few times a year. I already have Edelbrock RPM heads and intake that I would like to re-use. My main question is how many cubes the intake and heads will handle up to 6K rpm. I would build a 331 for torque if the heads would handle the flow.
Is anyone running RPM heads on a 331?
