Default 350 XE274 cam #13 Heads. pump gas?

The trans is a muncie 4 speed. Not sure on the rear gear ratio.

The pistons are speed pro. I think thats what they are called. They come in a Black box with red lightning bolt. Think they have dual valve reliefs

So is the Wallace racing calculator not correct in this case?

Thinking back, I think those 13 heads are around 78 to 80cc`s anyway. Not the 72 that the "book" says. 12`s are closer to 72cc`s.
