All right first things first if you just want to post about how I'm ruining the value of my car, or this is sacrilegious please keep scrolling I don't need your comments.

If you're genuinely curious and willing to offer some help please feel free to share your knowledge with me. Here's a little info to start.

I'm from Oklahoma City and I drove to Tennessee and rescued this 1966 Pontiac Star Chief Executive 4-door that had been sitting outside since 1993.

In my past I've had several different race cars but I just sold my last one which was a 1994 Pontiac firebird formula with a 350 cubic inch LT1 carburetor swapped and lots of nitrous. It did wheelies and it had a best pass of 10.177 at 129.9 mph. But for the last 2 years I I didn't take the car to the drag strip I found myself doing little local cruises and cars and coffee type events. So I got rid of the car and started looking for a late '60s land yacht to build a family cruiser out of.

After doing lots of reading I've learned that the 389 under the hood has a very weak block being a 1966. For this cruiser build I'm wanting a Roots blower sticking up out of the hood and some massively wide rear tires.

I've already got the back tires and appointment scheduled to have the car modified to fit them but I'm going to be running a 31"/18.5”-15” Hoosier QuickTime Dot.

I already have a stock 454 Big block Chevy disassembled in my garage and that has peanut Port heads and a nice low compression ratio for boost. I'm not wanting to build a race engine but just a fun weekend cruiser with a blower. I'm not after any specific horsepower numbers but I just want to make lots of low-end torque to move this big heavy car.

I've done a lot of searching but I can't find any really good write ups of people swapping big block Chevys into Pontiac b bodies. I already know the transmission won't bolt up directly but that's a very simple change with the bell housing. I think what I'm going to run into issues are going to be motor mounts and exhaust manifolds / headers.

Is there anybody in here who has put a big block Chevy into their full size Pontiac b-body? If you have please let me know I'm going to have some questions.
