I was wondering if anybody has seen these 2 motor's in action, in person. I need a daily driver, that'll pull good. I've already narrowed it down to these 2 motor's, but I don't know anybody that's seen them in person. I'm putting it in my: 1986 K10 Saginaw 4 speed, to replace my wore out 200k, 305. Anybody know which is better for daily work? Thank's for any information.
