Yes, it is a M1 single plane. We will be running it with the water passages blocked so as not to heat the incoming charge.
The rest of the build is Molnar crank and rods with Icon forged pistons. Brian worked the heads a little and gasket matched the intake. Rockers are Jesel 1.7:1 and Jim at Racer Brown ground a custom solid roller cam. TTI headers will go into a full 3" exhaust.
