Oldsmobile Motor Mount Location

[Magna86]

Good Morning Everyone. Are there different locations on the engine cradle for the motor mounts? I'm swapping an Olds motor into my 74. I'm using the trans am mounts on the block so I can use the clamshell frame mounts. Does the Olds motor sit in the same place the 350 was? Sorry if I missed this in my search.

Thanks

I don't think it would use the same holes. I know on the F-body subframe, there is a couple sets of holes to accommodate both engine families.

only if you use the strong 260.
joking lol, the square bodies have, up to 80 i believe, at least that far(no idea furhter) 2 sets of holes in the frames to.. im not sure what they are for difference wise actually, but an olds 350 diesel sat in a truck on OE parts and I want to say i recall reading an OE fitment of SBC parts in some fashion

does it have to do with BOP/Chevy trans? move the whole thing a lil to clear the firewall(i dont know how its different) or i recall a BOP had a longer tailshaft?

I know the F and A body cradles had different holes for different engine placement. The last motor this thing has was the Chevy 267 which is understand is about the same level as the Olds 260. I know the diesels had different mounts so we need someone who has access to one to see if the mounts are in same place as SBC. I'm installing an Olds 330 with Holley EFI and a 2004R and upgrading rear to posi. I have a bare block I'll be using for mock up

@OldBlueDually has an Olds 455 in his truck. Maybe he can help.
