They are B1 MC heads with 14:1 compression
It has a Moldex 4.665 billet crank with 4.5 diamond gas ported pistons
It was built by Scott Koffel in Huron Ohio
I certainly can provide the build sheets with prices if nessessary
As you can see it's a pretty serious motor and would cost WELL above what we are asking for it to duplicate
For the right deal I would possibly be willing to deliver it to you myself on the engine stand, dump some fuel in it, let you romp on it some, I'd like to romp on it a few more times before she goes, then help you unbolt it from our stand and place it onto yours.
Throw it in your chassis this weekend and start winning races next!!!!!
