FYI: V-8 engine stands... Know em - Page 2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Here's my mounts from my '68 V-6 GMC.
The engine was missing from this truck, but the original LH fender still had the "GMC V-SIX 1500" emblem.

Has anyone seen these with the 3 drilled holes?
They were also locating in the "forward position" frame holes.

Are they worth anything?
I was going to scrap this frame eventually.
Maybe I should pull them off and save them.

On the V6 mounts, yes the ones I've seen have the 3 holes like yours Keith

I've read somewhere that a SBC can be installed using '72 BBC engine towers (the ones that bolt to the frame). To make this work I need to know what clamshell mounts are used (these are the ones that bolt to the engine block). Either BBC or SBC - are they the same? Also what rubber mounts are used - these are the ones that bolt directly to the '72 BBC frame towers. Do I use '73 up SBC or BBC rubber mounts?

Any help is greatly appreciated.

I used these tubular mounts for my big block. It took the confusion out of it.

Here is a picture from the GM parts manual to give a general arrangement.

Funny motor mount story:
When I decided to pull my stock 350" engine out and install a new 502" crate motor in my 71 C20, I didn't know I needed to get a BB motor mount assy., so I just plowed ahead using all the SB stuff.
When things weren't lining up or fitting just right, I just thought it must be small casting differences in the new 502" block and the "older style?" 454 block, so I would make small mods as I went on with the install. I had already noticed one big difference, that was the new 502" block didn't have facilities for a mechanical fuel pump,(Which I was not happy about."), so I'm thinking "What all else might be different?".
Anyway, it's been 8 or 9 years since I did this swap, so I can't remember all the details, but I do remember two things I had to deal with. Having to shim up both brackets off the frame about 3/8" for some reason and then when I installed the headers I had to notch and re-weld the drivers side bracket a small amount.
Now, just in the last month, I pulled the stock auto. trans. out and installed a Muncie 4 speed, which required, among other things, installing a clutch pedal and linkage. I then had to do a few little modifications to the clutch linkage. At least on the positive side, the stock drive-line, yoke, and cross-member, all re-bolted right up to the Muncie.
Anyway,I still don't know how much of this extra work was caused by not using the correct motor mount stuff, but I do know this. It all works great, and I love my new 4 speed. It's made it like a whole different truck to me. It's like it has added another 50 HP, and now being able to row through the gears with a Hurst Shifter, like in the old days when I was a "Young Buck"!
I guess I'll never quit saying "Live & Learn" and "I Love Horsepower"!

I put my 350 in the v8 location (forward) using 6 cyl stands. Drilled an extra hole in the bottom and everything worked great.

Thank you to all for your input on this subject. It will help me replace my BB Olds motor with a stockish Small Block Chevy.
