RE: good shot. |

That's a great shot of how the frame can and probably should be done. I don't think there's anyway that you reduce the integrity or strength of your pickup frame at this particular spot. If I were to ever do this again, I'd do it just the way you've shown us Barry.
The way I did both my father in law's '71 and my '68 was to cut the bare minimum but allowing an 1/8" extra clearance for the manifold. Just used a Saws-All and cleaned things up with a file. My father in law drove his '71 with a nicely built 390 for years and no problems. This is the eigth year since I cut the little quarter moon notch in mine and again, no problems. And I don't take it easy on my '68 F 100. The current 390 hauls balls and loads regularly.
Another local friend did the same cut on a '76 F-150 4X4 with 428 and shorty HP manifolds. This truck is used for everything, fishing, camping, hunting, etc. Same friend who used to go deer/pheasant hunting with a beautiful '70 Cyclone Spoiler SCJ/3.91 car. |
