Engine Mount Dial-In

[MacAttack]

Bought this kit a while back from www.performanceonline.com with everything included. Nice quality. Instruction sheet said 'there may be some drilling and welding required.'

Not a big deal, but when I mocked everything up last Saturday I found the motor mount centerlines on the engine are at about 17" and the tower bushing centers are only 15-1/4" from each other.

1-3/4" off.

Three Options:

* Notch the frame rails 1" on each side - drill new mounting holes - and maintain engine height.

* Piggy-back weld another set of bushings (that intersect into the motor mounts off the towers) on top of the originals - maintaining the original geometry.

* Make two machined blocks that go over the original bushing length (and bolt thru them) with three different holes that allow all the adjustment I could ever use.

Thoughts?

I would say the best way would be to trim the top flange on the frame and drill new holes. Just my .02

I'm with Captainfab on this one-
just installed the 454 in my 66 and had to take about 1/4" notch out of both top frame rails to get the big block frame towers aligned (outward) properly

I think you're right guys. Looks like the easiest solution.

looks good....but......where is that brand new 283???

That is my engine. Just trimmed the rails and the bolt holes lined up. No drilling nesesary.

Yep - it is, and that's exactly what I'm going to be shooting for Saturday. The best solution I've seen so far, and I dig those lead-in angles to the notch. I think I might have to go a bit deeper, but we'll see.

Thanks for the perfect example.
