maybe you should have started your thread by saying what you are wanting in a motor. we could have steered you in the right way to start with. 250's are easy to find. gm made them from 1967 - 1985?
you need a motor with a non integrated head (like the one you have), use pistons for a 307 chevy v8, rebuild the stock rods, pick a cam and do some serious head work.
these engines have a small aftermarket to support them and a wealth of knowledge held by the guy's that have done these for years.
maybe go to the CLUBB STUFF on the left side of screen and buy the INLINE 6 POWER mANUAL to get started.
