1971 sb 350 motor mount question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

bmfpeterson · 08-07-2010, 01:02 PM

I bought my sb350 block from a guy that had it in a mid 80's truck. so the mounts on the block that it came with is what I am questioning...

I have the correct brackets that bolt to the frame rails of my 71 but I cant figure out what I need from there.

are the motor mounts on the mid 80's c10 the same. please help the motor is going in next Saturday.......

any pics of 68-72 sb 350 motor mounts would be a tremendous help......
Thanks

I don't think so. At least those that I have seen for '73 up look like a bolt thru the side to attach the motor mount to the tower.

Now when we put the 454 in my '71 we used the complete '73 set to mount the motor.

I have a 80 c10 350 in my 67, not sure if the mounts are from the 80 but they don't line up with my 67 x-member (now a 69 x-member). I just drilled the 1 hole that didn't fit and it works perfect. It lined up on top of the frame, but on the top of the x-member, my mount only had 1 hole and it did not line up with any of the ones their, quick easy drill and worked great. I used a template from my old bent x-member, traced it to paper and drilled up. PM if you need help mounting those or just buy the correct ones. Good luck! I have some pictures in my build thread.

Do you have the clam shell or the screw threw the motor mounts?

So Im not that crazy! there is only one bolt that holds the mount to the frame/x member mount!

and the motor mount has three bolts that bolt to the motor! I thought it was that easy!

Thanks dude!

I realize this is 2 years old but how does the 3 bolt work? Does the bolt go through the tower side and up to the mount? Does the mount act as the bolt? Or is it the apposite? Please have patience, this is my first project.
