Hi: Does anyone know if there is an aftermarket replacement for the original C60Z-6250-B cam that the 390 GT's and 428 CJ's came with? Are the aftermarket cams equivilent to the original Ford part? Or are they even better? Any idea what an orininal cam is worth? Thanks, Trevor

A good aftermarket replacement for the 390 GT cam is a Comp Cams 252H high energy. It's basically the same grind as the 390 GT. If you want a little more bang for your buck, try the 268H High Energy cam. It's very streetable on a big block, but increases torque and high end performance without affecting vacuum operated accessories. I have the 268H on my '67 GT 500 428 PI and I like it a lot better than the original cam. Idle is just a bit lumpy, but throttle response and operation through 5000 rpm is fast and smooth. The only drawback I noticed over the 390 GT cam was a drop in gas milage (from 12 mpg to 10 mpg at 60 mph).
