I have a 1976 skylark, I remember reading on here somewhere about a year ago when I put the 350 in place of the v6 about using the v6 motor mounts, I thought it was said that the 350 mounts would raise 1 side higher than the other. was I reading it right? the v6 mount on the pass. side seems to be broke after 3500mi. can I run the 350 mounts? and what is a good brand? thanks, keith
All you need to do is search this forum. I came up with this thread, http://www.v8buick.com/showthread.php?260340-3-8-opinions-please&highlight=motor+mounts From the little I read, the v6 and 350 use the same frame pads and motor mounts, and the 350 is a drop in, and why shouldn't it, you could get one from the factory with a 350. As far as motor mount brands, in this day and age, I bet all the mounts are made in China and just re boxed under different brand names. I'd just go to www.rockauto.com and get the one with the best price. Just took a look at rockauto, the mounts are different part numbers for 231 and 350, but that doesn't necessarily mean they won't all work. I would compare the pictures to what you have and replace both mounts.
Back in the 90's I was burning through drivers side mounts every 10k with my 231 odd fire. I kept getting them at Napa. After the odd fire died I swapped in a 79 even fire stuffed with a bunch of Kenne Bell goodies, offy intake and a set of headers. I never had another problem with the mounts.
with mine it appears to be pass. side, really rocks over going into reverse from park. idle rpm in park is 750, 550 in gear
Update! after battling for 2 wks over motor mount issues i found that on my 76 skylark that came with the 231 v6 that the frame pads are indeed different from the v6 to the 350, before i installed the motor i purchased new 350 motor mounts and installed when i dropped in the motor, the mounts wouldn't let the motor drop down far enough to put the through bolt in, ( by about 3/4" ). since i got those from auto zone or one of those other chains, i have found that what they say fits buick doesn't usually, so i ordered a set from TA, same mounts, so on my X-body atleast i know that frame pads are different. (i went back with v6 mounts again because i don't know where to get the frame pads for a v8 except wrecking yard and i'm really not wanting to pull lower control arms again). By the way i have 2 sets of brand new 350 mounts if anyone is interested. Keith
Finding a X body (73 - 79) with an engine other than the Chev L6, V-8, or Buick V-6 is a fairly rare find.
