BBC Motor Mount, Please Help I.D. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I just pulled the 402 big block from my 71 C10 and noticed the rubber mounts on the frame are stamped made in Korea. Should I keep these or swap them out for some poly mounts? The driver's side is stamped #2395. Can someone tell me what year mounts I have?

72armyswbtruck · 03-07-2010, 11:48 PM

Those look like 73 and up BB motor mounts

35spline · 03-07-2010, 11:53 PM

They look almost new but I am wondering if I should swap them out for something better as long as the engine is out. I am not sure if there is something better, polyurethane maybe.

Your motor mounts and stands are 1972. One year only.

**too much stuff** · 03-08-2010, 12:01 AM

Look like the 1972 stands. Just buy some new mounts as long as it as apart and you should be fine if you are worried.

X2 1972 motor mounts and stands. You can replace the motor mounts by buying 78bigblock mounts, I might be wong on the year but you can get them new I did they are not that expensive neither.

I agree, they are definitely 72 only big block mounts. A lot of folks get them confused with 73-87 mounts since they look similar.

The way you can tell the difference is by looking at the raised lump on them where they sit on top of the frame. 72 big block mounts like above have one raised rib, 73-87 have two raised ribs.

those are exactly the same mounts that i have for my 68 and im wondering the same thing what yr mounts are they?

**leddzepp** · 03-08-2010, 01:19 PM

As stated above, these are 72 BBC mounts.

35spline · 03-08-2010, 07:32 PM

I have not been able to find a polyurethane mount for the 1972. Does anybody have a part number?

71 super · 03-08-2010, 08:48 PM

One more for 72, 73 up have two humps on the stand 72 have only one. Any of the clam shell inserts in poly should work as replacements for your mounts, the inserts are the same from 72 up.

**leddzepp** · 03-08-2010, 08:49 PM

LMC carries the BBC poly mounts for 72.

matt67350 · 03-08-2010, 08:56 PM

They are 72 BBchevy mounts. Check Napa Auto Parts.

71 Super If you are right about this I could get a poly insert for a 73 and up but would it still need to be for a big block?

BurnoutNova · 03-08-2010, 09:41 PM

I scored a set of these at a local swap meet sunday for $160. I can't decide if I want to put the 402 I have in my truck now

breeh · 03-09-2010, 12:55 AM

I used some extra inserts that I had from my 73 Camaro in the 72 truck mounts. Same deal.

**Tom Vogel** · 03-09-2010, 01:31 AM

Yep... Ive got 72 mounts in mine and have poly inserts. I beleive the inserts are the same for a number of years after 72. I beleive mine are Pro Thane or shoot I cant remember... The company with the yellow and black box... someone help me out here...

35spline · 03-10-2010, 12:39 AM

I saw some Energy Suspension (pn 31116) poly insert mounts on the shelf at the local speed shop and decided to try them. The box said they fit a late model Chevy. They looked about right but ended up being too thin.
