Was looking at the rear end thread, good thing you guys are here to help folks out. Almost as bad as my nephew (24) He bought a $100 1969 Couger and wants it to be the fastest car at the track. He's never been to a track before: I am trying to convince him we need to build about a 400 HP 351W for it. get him around a 14 or 13 second car and go from there. He found his engine kit a crankshaft kit that is good for 1500 HP.......OK.....slow down you don't need that,,,,,I don't know a whole lot about building a race car but come on............
