What motor mounts should I use, 1978 Phoenix???
I have a 78 Phoenix which was a v-6 car. V-6 died so I pulled it. I want to use a 1973
pontiac 350 from a firebird to replace it. I have the motor mounts including 2 long bolts
still attached to the 350 but Im concerned they may not work because the part of the
mount which is attached to the frame looks as if it is much narrower than what would be
used to attatch to the 350 pontiac mount. help?. Someone said use a Ventura mount?
Your 78's frame should be the same as my old '79 305/7 parts car. I actually pulled the v-8 mounts off of it to put my 350 4-bolt chev engine in my '80 LeSabre which had a 3.8 v-6. I do know that the BOP's used a variety of different engine mounts. I'm thinkin you need to hit the wreckers. Speaking from experience do everything you can to change the mounts on the engine because I still remember 12 years ago trying to do the bolts up on the frame engine mounts behind the a-arm's. (lived a ways away from any wreckers had to make do with the parts that I had) Here is a list of GM x bodies to search. I think all had v-8 options. Buick Apollo (1973–1974; 1975 sedan only) Buick Skylark (1975 coupe only; 1976–1979) Chevrolet Nova (1968–1979) Oldsmobile Omega (1973–1979) Pontiac Ventura (1971–1977) Pontiac Phoenix (1977–1979)
Thanks yeti, yeah with a little more research I found another who said use the x-body mounts for both the motor side and the frame side. So 35$ later which is cheap for all 4 parts, I'm eagerly awaiting those deliveries to show up so I can start in on this thing. Thanks for the x- body interchange list..super helpful, I'm going to write down that list. Thanks for any other feedback from others who wish to chime in. - Adam
If your doin the frame side mounts I recomend finding a small flexible grabber tool with a built in magnet. It will hold the nut up there better than just one or the other. Sucks when the hardware takes a bad bounce and you have to dig for it in the frame. 12 years and I remember the pain. Good luck.
Lol, I know it won't be easy. I'll probably put a dab of grease on the magnet part of the tool to add a little more holding power. Thanks for Sharing your experience yeti. It'll help.
