Motor mounts

[OldRedFord]

Anyone know what the proper torque is for the bolts that hold the motor mount brackets to the block on a 460, and also the bolts that go through the isolators?

Good evening Tim,

Anyone know what the proper torque is for the bolts that hold the motor mount brackets to the block on a 460

While I'm not sure about a 460 per se, the 1972 Ford Truck Shop Manual calls for 45-55 ft/lbs on the 7/16-14 bolts that hold the motor mounts to the sides of the FE block.

Are the bolts that hold the 460 mounts to the block also 7/16-14 bolts? If so, I'd imagine that 50 ft/lbs would be a good amount of torque for them.

and also the bolts that go through the isolators?

Are your isolators the same style as mine? Here are mine: http://www.robroygregg.com/Number50/IMG_9871s.JPG

Are the bolts that run through your isolators held by nuts on the far sides, and are those nylon-insert locknuts?

If yes on both counts, the torque value may not be super critical there. I asked John at Autofab about the torque on those huge bolts and nuts, and he said that I should just make them good and tight, and that it wasn't critical. I think that's because the forces upon them aren't trying to make them pull out of the insulators in that way.

The last time I put those bolts and nuts together on my setup, I set them to 35 or 40 ft/lbs, if I remember correctly.

I wish you good fortune with this Tim!

The are 7/16 bolts. Ill go 50 ft/lbs then.

My isolators look like these.

Sounds great!

Oh, I see! I'm totally unfamiliar with those. Perhaps somebody has access to a 1973-up Ford truck manual with that spec in it!
