radiator overflow

[awd-turbo]

How much does the engine move with the FFR engine mounts? I have a 351w block, so I am looking for a little larger over flow tank. The one I have is 3inch in diameter. But it comes with in an Inch of the alternator. Anyone see this as a problem?

My big block moves quite a bit. Where the original overflow bottle was mounted, there was plenty of room for it to be there without hitting..but it was too small for my 429 so I had to get a bigger one, and relocated it. An inch is a bit tight for my liking, but i don't think it will hit when the motor torques over.

It could be close but I'd run it and see. If it's just the alt body no immediate big deal if it does hit. If it hits the pulley or fan, still no immediate problem. Worst case, even if it were to cut through, you don't need that coolant until the engine is cooling down.

I have a 351W and a taller expansion tank mounted close to alternator. Like 3/4". It doesn't touch when engine is moving.
