No sharp edges on the pistons.

Yes I did just use my normal deep valve pocket that gets used on big effort engine ( I knew what the CC would be with in 1-2cc)

Correct icon is not in the custom piston business this set was done as a favor to me.
They really should get into the custom piston market they make a nice piston.

Sorry not talking about cross section of my heads 😉 Got told many times on here how wrong my stuff was.

But the CC of this port is 303 😀 If you Know the port length of a w9 you should be able to figure avrage cross section.

Cam specs are wrong in this engine I missed it trying to knock some cylinder pressure out of it. I did 😂 She only cranks 160lbs

I really would like to change the cam but it's not in the budget on this engine. Hope we can make some changes down the road.

Short list of some changes.

New bigger/better carb
Port the intake (was done poor when built by previous builder) but works better than I thought it would.
Crank trigger
Really think a vacuum pump would help power a good bit.
Better oil pan Just has street type milodon I would guess this is really hurting 4.125" stroke.
