I have a motor here that came out of a crashed car, motor and parts show that it has very very low miles since built. There was a very small crack on the lower cradle that was removed and welded inside and out, got to see inside the motor when removed and it's very very clean.......like new!
Motor has...

Arp main and head studs
Eagle rods
Manley pistons
Ferrea valves
BC 272 cams/springs
Newer timing chain
All cyliders have less than 5% leakdown.
PM me if interested, price is pretty firm and i'l ship at buyer's expense.
