Very fast Comer P51 blue printed my Jim Stroud at MISI.
I have two of these motors, both for sale. I have two drivers and gears plus extra carb boots, headers and mounts. make me an offer on one or the pair. both have a new piston and have not been run yet and need to be broken in.
bore is 50.30 on both.
$1100.00 or 2100.00 for the pair
I will also consider a trade for a K71 or other karting related stuff
