Engine mount questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm replacing the engine in my '67 after I pressure wash and clean up the frame and suspension.

So my question is, is it easier to remove the frame mounts as pictured and bolt them to the new engine mounts first; or leave them in place and just try to line up each bolt to the engine mount to the stands when going back in?

Leave them as-is

I'd straighten out the trans first though

Thanks - Trans slipped a bit on the jack - will be sure to align properly before going back in....

I would loosen the bolts on the frame mounts so you have a bit of play to make it easier to get the center motor mount bolts to start as you lower the engine.
Here is a link to a couple of motor mount tips.

I would also loosen the frame mount bolts, so that they can wiggle a bit. It's a pain to loosen and re-tighten them, but totally worth it.

Would this be the time to convert the mounts to the single center bolt style somehow? If so, what would be needed?

I have my motor out right now and yeah it was a PITA to change the mounts when I bought the truck.

I agree - a single center bolt style would make life much easier. Has anyone done this ?

The attached pic is from another group and is a '79 C10 - wonder what it would take to convert to this style?

I have a set that came off a 67 with a 350 in it if someone is interested in them I can list them in the parts section for sale .

Are these stock ‘67 stands or single bolt similar to the picture?

Single bolt ,They came on a unfinished project truck small block with headers I bought a while back .I sold the engine to a member here and the frame locally .

Can you show a picture of the standard and single bolt style that you guys are talking about, side by side? I would like to know what you're talking about.
