How do I put a pontiac BB into a 63 chevy c10 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

raphyel · 08-19-2004, 09:38 PM

I have a 63 shortbed fleetside that I am restoring. I am trying to make a pontiac fit into it (1970 gto motor). I am trying to get some help on figuring how someone may have done it. I hope someone may have some info that will help me get the thing mounted so I can put the cab on and the front end back together. Any help will be appreciated.

Thanks

I don't know how much help this is, but I had a 63 C20 with an Olds 350 in it, and it was a bolt in. There were no adapters, welds of any sort.

Someone had told me to try thr 67 - 72 big block chevy brackets to make the pontiac big block fit. I went through two sets of mounts before I got it to fit, But the flat brackets when coupled with a 1970s trans am motor mounts was a perfect fit. I tested the angle of the drive shaft going into the rear end and it could not have been a straighter line. I appreciate all of the help you guys have given me. Maybe I will have it done by this time next year. I am doing a full ground up restoration. Well anyways Thanks so much.

That sounds like a good tech write up.

I have pics of the mounts as they were installed. My block still has to be bored and put back together, but I wanted to get everything lined up so that I could tie the cross member in and put the cab back on the frame.

Here is a pic of how the chevy big block towers fit. The pontiac motor mounts look very similar to the chevy big block motor mounts.

Good topic

As soon as I get my daily driver going again, I'm going to put a 400 Pontiac in my 72 Blazer.

Gotta love them Pontiac motors. Gobs of torque and beefy bottoms on them

How are you planning to install the pontiac? Have you found a different method to make it fit? I am just curious, I am really into pontiacs above all other engines.
