The great cornholio
I’m building an open motor for one of my best friends, it’ll be stroked .080 and have a 2.795 bore making it a 222cc. We’re purposely pushing the envelope with this one as it’ll be on 25% nitromethane and 75% methanol to see if the block will take that kind of cylinder pressure.
Specs are
.040 overbore
.080 over stock stroke
Wiseco 2 ring piston .490 wrist pin
ARC 3.595 billet rod
14 cc fully ported 32/27 head
Unknown cam with .298 lift
1.3 roller rockers
Chromemoly pushrods
NR racing 390 carb adapter port, matched
Highly modified GX390 carb
ARC billet flywheel
I’ll post pictures later tonight. I’m waiting on the new crank and I had the block decked .020 so I’m waiting for it to come back from the machine shop.
