i am wanting to build a rally engine, i have a 1400 spi which will be getting ripped off and replaced by a set of twin 40's, a highlift cam, 1300 head which i have heard makes a big difference! Also a 4 branch with full system and lightened flywheel. I would like 2 know roughly what kind of power i should get out of it. Cheers
