Re: Aluminum inner fenders?

Yes truck 12 bolt. 3.42's, Eliminated c clips, big bearings @ axles, Ferd drums, Mark Williams axles etc.

Here is a 657hp steel headed version of my engine. Mine has aluminum heads, and 50 more hp. I realize this guy is in an arrow and I'm in a brick! His gears were 3.08 at the time of this video. He has since switched to 3.31's and has a best of 10.59.
