Item description

I have for sale a 639ci Pat Musi Big Block Chevy race engine combo. Originally built as a 632 and now fresh at 639ci with a 4.625 bore. Proven drag race setup that previously ran consistent 4.70s–4.80s with Edelbrock heads before being torn down for a freshen-up.
Combo includes:
* Pat Musi BBC block
* Eagle standard/standard crankshaft
* Lunati rods
* 7 original pistons
* 8 additional brand new pistons
* All accessories shown in pictures
Engine was running strong when removed. Not a blown-up or hurt motor simply disassembled to freshen and update. Great foundation for a serious bracket car, dragster, or door car build. This is real race hardware for racers who know what they’re looking at. Throw rings and bearings in it, bolt your top end on, and go racing. Additional pictures and information available for serious buyers only.
