While I'm still generating a lot of grinding dust and welding fumes on my C4 suspension transplant onto my spare '69 frame, I'm trying to narrow down my choice of parts for my next street/track day engine. All my previous build useage was with Chevy cranks and rods, but trying to find a 427 crank these days is getting difficult. Along the way searching through catalogs I keep running into Scat and Eagle parts. I'll confess I know little or nothing about these guys. Any first hand experience with these to let me know if they're worth considering?
