Might not be the right place, but I’m looking for Pontiac 301 engine side mounts for my 86 Grand Prix. I’m trying to swap a 77 Pontiac 400 out of a LeMans and it doesn’t seem to line up…but damn it’s annoyingly close. Can anyone help point me in the right direction?

301 mounts are the only ones that will work and they are hard to find.

Are these tough to build? Is there a reason they aren’t available in the aftermarket? I mean, it’s certainly a niche market and I understand that. I’m not a fabricator and I wouldn’t even attempt it, but I know people who would be capable I would suspect.

eng mounts or frame mounts? The 301 to my knowledge was discontinued in MOST cars by 1981... So pre-81 will be your best bet to finding some. Try the Firebird groups/forums.

The rubber engine mounts on the frame side are easy enough to come by. I’m told the 301 engine side mounts are different for the G Body compared to the F body mounts.

Gotcha yes, i figured you where looking for the cast mounts. All i can say is good luck. It took me awhile to even locate some for my 3.8 buick! $125 later...

Maybe one of the 3 Grand Prix has them? Engine search was 301

Thanks for the help! I’m going to call a place in Kansas City that might have them and start working my way through car-part.com. I also talked to a guy on this site that might have some!
