what hd parts should i use

Well I got my hands on a sparks 330 I just don't know if I could use a stock trans or if to get a yukon. I would assume I would need a over sized raidator also?

I was thinking id use a 39as or pwk. With my lrd 350bb pipe.

I think your stock trans would be fine. Thats what I run on mine. I also have a stock raidator too. It cools it just fine but I have a temp gage on it to make sure.

Where do you have your temp gauge, what line?

I just talked to Laz at GT Thunder about the big bore cylinders on the market. According to him, these cylinder actually tend to run cool, and also will not expand evenly due to the large water jackets. He claims that a large number of them will also wear unevenly due to this.
