Well, I had a Procharger installed on my 5.3L suburban quite a while back, and I ended up deonating and wrecking the entire motor, so that meant it was time to rebuild.
I took it to San Diego Superchargers and they built me an entirely custom motor to accomidate the superchager. It is now bored out, and it now displaces 363 CI. It has a custom ground cam, ported and polished heads, ported intake manifold, forged internals, and much more. It is still getting the last bit of troubleshooting and tuning done to it, but I'll having plenty more info soon.
