Purple Shaft 280/280 cam

Well, I will think about all those options, and talk with the guy who will build the engine. He is an expert in sb's, with almost 30 years working on it. He really likes the purple shafts, he says "It's hard to tune, but is good as hell".

I will consider all opinions here, you guys helped me a lot. But I really trust the engine builder, he has made lot's of nice engines, including the 360 I posted here.

I would like to see more vids, if possible. :-D
