inspection of parts for was done before assembly was done by myself and a couple of my career mechanic friends. pin inspection was eyeballed and not taken apart to measure clearance. piston to valve clearance was good to go. was never a problem with dish pistons and not a real wild cam. engine was sent to scrap. when you gather all your parts up and have the machine shop do their thing and take your stuff home and assemble it yourself your on your own around here. like i said earlier this was about a five year process where i would buy parts when i could (eagle crank,resized gm rods,crower cam,summit pistons (kb),new valve train,summit intake, edl,carb). myself and my lifetime car friends have been doing this for 50 years and nobody can believe what happened here. this was my retirement project. crank,bearings,and rings looked perfect. this left a bad taste in my mouth, won't use this machine shop again. assembly was done about 2 years after work was done when i retired.
hindsight is always 20/20. i'm lucky to have some career mechanic friends around here and engine assembly was never a problem. but yes,warranty is always very good.
