engine perch mounts question
 

I am placing a V8 350 in place of the 6banger. What holes should I use on the frame for the perches to mount to, front or rear holes? or does it matter? thanks

It doesn't really matter, but the front holes will give you more room to grab the distributor.

You might also want to look at your driveshaft length. Whether one position will work better than the other one.

The V8's used the rear set of holes the same as the 230 & 250 6 cylinders. My son and I just installed a 350 in his new '63 4x4 this past weekend. With the engine in the stock location, I can easily fit my hand between the HEI and the firewall. In the rear location, you get a little more weight towards the rear too. More weight on the rear means better traction. If you do decide to move the engine to the forward holes, the motor mount brackets for a small block in the '67-'72's are what you want to get. The small blocks in those years are mounted in the forward position.

If you're using the stock cross member mounted bellhousing , that will dictate which holes you use . And by doing so , no other changes ( i.e. - driveshaft length ) will be needed .

thanks for the info !

Has anyone experienced better exhaust manifold or header clearance by using the back holes vs the front holes?

Thanks,

If you are running rams horns it does make a difference. If you mount in the rear holes you can use the outlets that point straight down. In the front holes you must use the ones that are angled toward the rear, and of course those wil work in the rear holes as well.
