A fresh engine for my 88 S10. Motor at present is a early model 305 high miler from some truck. Starting point for this new build is a basket case 305 Vortec from a 1999 van i bought in peices for $260, the crank was toast from running the motor with no oil. Most of the parts im using for this build are from a priveous 310 roller that i built that spun 3 cam bearings and lost oil pressure.
