Engine mounts?

[jason7698]

I have a 1971 c10 that I'm putting a bbc in and need some motor mounts can someone help?

We put a '73 454 in my '71 C-10 and had to use the motor mounts and stands from the '73 so the headers we had would fit.

was yours automatic if so what about the linkage and drive shaft? The bb stands move the engine back 1" I'am in the process of the same project.

My '71 had a 350 in it with a SM-465 manual transmission. I wanted to keep the SM-465 when we put the '73 454 in the place of the 350 without having to change the drive shaft.

We dropped the 454 in and mated it to the SM-465 and let the engine settle into the cradle. Then we drilled holes in the frame to bolt the mounts.

Every thing worked out good, we were even able to use the fan shroud from the '73, but did have to relieve it a little for the crankshaft and the alternator.

The clutch operated fan fit perfect in the shroud and had the correct clearance to the radiator.

I am having my driveshaft cut down as its gonna be to long. I guess I should have ask where to get the bbc mounts?

The motor mounts and stands I used were the BB stock ones out of a '73 C-20.

I have heard others used after market ones.

I have a set i am swapping in a vortec 5.7 mine are just laying in the shop floor at the moment.

Will I need stands and mounts?

If your are switching from a small block you will need the stands and rubber mounts I had to switch mine back to the small block stands and mounts to get mine ready for my vortec 5.7 if you search the google bar up top for engine stands you will see the difference and what ya will need.

I used these for my big block swap. Bolt in, no issues here. A bit pricey but worth it imo. The big block will bolt onto the small block stands but you'll run into issues when it comes to bolting up headers. The big block stands droop next to the frame rail to clear a header tube whereas the small block stands are straight. These tubular mounts solve that issue as well.

Jason doing the same project I got a set of the 1972 stands and clam shell mounts the bb mount puts the motor back 1" further then the sb stands. removed my drive shaft and pushed the motor and tranny back 1" and every thing fit fine.NO wait the auto shifter lingage is different on the bb.so thats where i,,,am at need shifter linkage and shorten shaft or get a new one piece.
