Anti-sieze or loc-tite?

[otter]

I have a set of aluminum frame pads to bolt onto my frame so I can install my 455. The bolts are steel. I painted the frame and I painted the aluminum pads but the bolts will be in direct contact on the threads. I don't want corrosion from dissimilar metal contact to be an issue so I was going to coat the threads. Should I use anti-seize so that I can get them apart and keep from stripping the threads? Or should I put loc-tite on the threads to insure they don't back out and have the engine in loose? I am kind of leaning towards the weakest version of loc-tite

Anti-sieze will help delay the galvanic corrosion you're concerned about. If you have good thread engagement in the aluminum, proper bolt torque is all you need for the sake of retention.

I agree... I put the same frame pads on when I switched to a big block two years ago with nickel anti-seize and all is well.

anti seize definitly.... there are ways of keeping bolts tight without loc-tight.

I'm sure u know this but when u use anti sieze drop your torque value by 10 to 15% of dry torque value. If torque is 100 ft lbs then with anti sieze it would be 85 to 90 ft lbs.This prevents over torquing your bolts anb screwing up the bolt threads. hope tthis makes sense , later bake

Put the anti-sieze and the loc-tite in a drawer together and let 'em fight it out - whichever wins goes on the car. :Comp:
