it was a 6 cylinder car which is actually irrelevant because i bought it without anything on the frame.

joe,

this is a two piece correct? is the straight bar required to be used? or can just the piece that cross bolts to the frame mount be used?

Yes and yes. The straight bar bolts to the three motor mount bolt holes in the Olds block and has two studs that the U-shaped bracket bolts to. There's no other way to attache the U-bracket to the block.

Thanks joe!

one more thing, are those mounts available other than on ebay/junk yard?

Great thread! Thanks to Joe. I know this has been brought up before. But I can't find good quality mounts. My 71 Cutlass 350 had sagged so much the oil pan hit on the crossmember. My 70 Vista 350 had a small aftermarket flex fan on it when I bought it and when I attempted to put the original factory type clutch fan back on it, I found the mounts had sagged. I had to replace them to get the fan on. Now after 5 years or so I can tell the mounts in the Cutlass have started to sag again. Also the motor mounts on my 65 Coronet big block had sagged causing the headers to hit on the pitman arm. I finally replaced those with Schumacher polyurethane mounts and it raised the engine 3/4 inch. But I hate those! Car shakes like it has solid mounts! Anyone know of higher quality mount available?

I've seen them offered by Firebird/Trans Am specialty houses, but I don't know if those are used or repros.

Unfortunately there are no polyurethane mounts for Olds motors that I am aware of. Supercars sells very nice Olds mounts, though I have no first-hand experience with them. Other Olds vendors sell reboxed Anchor/Pioneer Chinesium mounts at far higher prices than RockAuto.

thanks joe! you wouldn't happen to have a set for sale would you? LOL

Sorry, I've got one set that's on the shelf waiting for some mythical future project...

thanks Joe,
i got the flat bar mounts from a member, and i found a set of the ones that bolt to the anchor 2387's on a firebird central site...

1964-1968 frame mounts (all) - use P/N 2261 motor mounts
1969-1972 SBO frame mounts - use P/N 2261 motor mounts
1969-1972 BBO frame mounts - use P/N 2328 motor mounts
1973-1988 frame mounts (all) - use P/N 2328 motor mounts

This is good info, my understanding is that PN 2261 is roughly 1-5/8 from mount engine mount hole to center of frame mount hole, PN 2328 is 2-1/2, you can also use PN 2286 which is a ford/mercury part number and it measures right under 2 inches. I actually ran that on my BBO for the last year. So it's in between the Olds mounts but still fits.
I'm getting ready to change to the taller mount so I have a spare set that I would be happy to send you Joe for verication just to put into the data bank of what fits and what will work I can see where this might be beneficial for some people doing engine swaps

Thanks Joe
Another question then.

Do I use the 2261 motor mounts since the motor is from 1968
of the 2328 motor mounts for the 1972 frame? With matching frame mounts of course.

Curt

The block doesn't matter; all Olds blocks have the same motor mount bolt holes. Just get the motor mounts that match the frame mounts.

thanks

Holy Snot Rockets. Exactly the information I was searching for. Thank you, Joe.

thank you for all of the info and sharing your knowledge with everyone
