Bore 3.660"
Stroke 4.02"
Length is very close to the 250, it fits into the same hole where I had the 292 installed. Its wider than a 250/292.
Manual trans .. bolt in - 5 spd out of a colorado pu. Others can be used - be it needs an adapter plate as the 4200 has an oddball bell housing pattern. I'm working with CNC dude to make an adapter plate - just waiting for CNC Mill time.
