[SCOTI]

The No.1 reason (drumroll please.....).... better geometry & HUGE aftermarket support.

If you clip one of these trucks w/camaro stuff, it rides like.... well, like a camaro. NOT like an old truck. Sure, updating to fresh newly rebuilt disc brake front end parts will bring a 67-70 up to date, but it won't out-handle an F-body.

I've ridden in a 67-72 swb truck w/a camaro clip & was impressed. Combine the 70 1/2 thru 81 suspension w/the truck trailing arm rear & there's mucho handling potential. Plus there's several co's making tubular arms w/coil-overs & hollow sway bars to lighten up the front end even more.

And don't forget the engine sits further back from the spindle C/L on F-bodies than w/a factory GM truck suspension.
