V8 engine mount help - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Red68 · 07-09-2019, 09:10 PM

I have a 68 with a 327 v8 and a factory 3 speed on the column that I have owned and drove for the last 30 years. I have pulled the sbc to install a 700r4 transmission and a few other upgrades. I am looking for some help with the engine mounts that bolt to the frame, they are in the “back” holes, I believe it originally had a 6 cylinder.
Can I use the current engine stands and move them to the front holes with the same engine? I moved them ahead after I pulled the engine but have not reinstalled the engine yet. Would they be the same? The only thing I can see I need to do is to drill a new hole for the bottom bolt on each side of the front frame cross member.
Thanks for any help.

No the six cylinder mounts you have are shaped wrong for the front location. You need to get V8 mounts and mount them to the front holes on the frame and cross member.

That's what I did. At the time I did not know the six and V8 engine brackets were different. It appeared the V8 engine would sit in the six cylinder brackets, and it did. I found that the 700R4 trans would hit the floor with the brackets in the rear holes, though. So I pulled the engine and trans back out, slid the six cylinder brackets forward, and drilled a hole for the bottom bolt. This has been working fine for me, I don't know if the engine is in a slightly different location than it should, but has not caused any problems.

Thanks Katrina/10,
That’s what I was planning to do and was going to check it out before I purchased new ones. Thanks!

I know what you want to do will work, but remember I have no idea whether it locates the engine in exactly the right place. I had to relocate the transmission crossmember for the 700R4 so that didn't matter. Maybe someone who actually knows the difference will respond.
