I had a few inquiries on this engine but folks seem to be confused about the cast crank. I'm offering basically the identical engine for the same price ($11,200) that is currently in my brothers 70 Firebird. Engine has a few street miles and about 12 passes at the track. Can hear it run before we pull it. It's basically a clone to the above engine but has a 4.21 forged crank, does not have the stealth package on the heads and is 4.190 bore. The car runs high nines with a tight nitrous converter and 3.9 gears weighing 3720.
If the 4.190 engine sells the 4.21 bore engine will no longer be availble as it will be used to replace the engine in my brothers car.
This is a video of the second to last time we raced the 4.19 bore engine.
