Engine Mounts/Header doesn't clear

Hello everyone. It's good to be aboard. I'm trying to put a Pontiac 400 from a '75 Grand Ville into my '70 Lemans. I first tried the mounts from the 350 I took out of the Lemans on the 400. It seemed to work fine until I put my headers on. The drivers side header cleared fine, but the passenger side header runs into the frame crossmember. I need the engine maybe 1/4" higher and it should clear.

I thought maybe if I used the mounts from the Grand Ville it would raise it up enough for the header to clear. It did, but it raised it too much and I would have to drill out the holes a little bit for it to work. I was looking for new mounts in an OPG catalog and found they are listed for '64 - '73. I'm assuming they are referring to the frame of the car and not the engine. They look the same as the mounts that were in the Lemans.

I have received a few suggestions about header clearance. One of them to put washers between the mount and the frame or the mount and the engine to give it a little more lift. I wonder if this will affect the stability of the engine. Another was to heat up my headers with a torch and bend them. That could work, but I wouldn't want to ruin the ceramic coating on there. Another was to start the car and when they are nice and heated up, use a board and push on them hard enough to bend them so they will clear.

Anybody have any suggestions for me? Any other mounts I could try? Any help would be greatly appreciated. Thanks in advance.

Joel

I guess you are using specific LeMans headers, which should work.

If your mounts are not sagging and need replacement, I would do washers or spacers of some sort.

That's what hot rodders do.... adapt, improvise, overcome..... like a Marine.

Yep, I agree. Washers with longer bolts is the way to go. As long as the bolts are tight, then you don't have to worry about stability. Leave enough room for the engine to vibrate without the headers rattling and driving you crazy. Good luck, post your results.
