Think I blew my 3400

Brad, ok thats what I thought, but the CRcalc a few days ago didn't have .020 as the value so I was lost. Now I see the FF one does for 3400. But it still doesn't work

Anyone have final say on this? I am trusting you guys implicitly so give it to me straight. It is a DD so pump gas is a must. 91 is most readily available but I guess I could mix with E85 100 octane to get higher but I would like to avoid that.

Edit: For the record I would be using ported 3400 heads with this. I am short of cash so this would be a deal to make use of a bad situation for me, I can't afford to spend much on this and the pistons make sense since I need new ones any way.

Depending how bad the pistons really are you could be fine. I had the exhaust valves hit mine last summer. I just sanded them smooth where they hit and Ive been beating the hell of them since Oct. Now im being then hell out of them more with 6psi. Soon to be 12psi daily so we'll see but so far so good
