I've got over 3000 trouble free miles (at least on the engine - had some fuel pump problems to iron out) on my FMC crate 460 w/ 535 hp. Hooked up to a TKO and a Stang 8.8 rear with 4.10's.
Torker II intake, Holley 850 cfm, and Canton flat bottom 9 qt. racing pan. MSD. Supposedly I have the first FFR BB kit. Lots of gas, but lots of fun too!!!
