I have a 78f250 that still has the holley 670 on it when i bought the truck in 2014. And yes it has a 460 in it. Unfortunately the block cracked on me last november.
Comp Cams FF 280H .530 lift 280 degree w/ 110 lobe separation hydraulic flat tappet , I appreciate it! The mufflers are actually summit brand knock offs of the magnaflows, but a lot cheaper
