This was before i messed up lol

I know I sound crazy but Im trying to hit 70 xD

This is my little manco got it up to 50mph but that was when the engine would only rev to 5k now it revs to 7+

Damn that thing is nice, I see the burnout marks haha. I might just order a stock piston if I can find one and that head

Arc 6773 says it has a .716" wrist pin but i cant find a 70mm piston with that size

Should I just get a flattop piston? If so which one would be the most drop in one for my application?

Heres the exhaust stud

Is it also ok to change the combustion chamber by grinding those out?

Rod is arc 6773 running a 265 hot cam, so upon further investigating I think some of my weld got down in the valve because i broke one of the exhaust manifold screw while trying to remove so I tried welding a nut on top but I guess I didnt cover the exhaust port, how do you recommend that I...

So to start with I recently rebuilt my predator 224, I already had a billet flywheel, cam, and 22lb valve springs, well I finally bit the bullet and tore it down to put in the new arc billet rod I had for it and some 26 lb valve springs but I got it back together and ran it for like 3 heat...
