yeah, i would agree. im just a lil over 11:1, only around 210 hp..... at the flywheel, so.... great info on that! i appreciate it a lot! right now im replacing bearings and crank.... oil pump went out, but caught it in time, so not too much damage. gives me an excuse for a new clutch and... a lot of other things too... keep talkin... might as well keep this post going... anything youd like
