I used a Paxton supercharger.
I have some pics somewhere???
I still have the Paxton & brackets,but it is an older SN 89 model.

It put out 9 psi on my engine, but I had a fairly big cam,thus reducing boost,plus ported head w/bigger valves.
Even with only that amount of boost pressure it ran mid to high 12's.

On a stock Chevy 250,you could get easy 15+ lbs of boost pressure.

You just need to make brackets on the right side of the engine attached to the cylinder head for any of the newer type blowers.

You can use the Paxton Novi 1000 or 2000, high boost.
Or a Vortech high boost model.
It is much easier to adapt a supercharger than a turbo.
