Hello. New here looking for advice and recommendations.

I acquired a 2003 Marauder in which the motor spun the main crank bearings due to insufficient oil quantity, and I am not sure how to proceed. The car has now been sitting for several years, aside from when I purchased it and had it towed to my house. The motor has been pulled and is now in my garage, partly disassembled.

What I want in the end is to have a docile and reliable stock motor (or slightly more HP) that has explosive acceleration when desired. For that I've decided that what I want to do is have a stock motor (or similar with equal or slighly more HP) with the addtition of a supercharger.

To get there, should I:

Rebuild the existing motor?

Rebuild existing with forged internals?

Buy used 2004 Maruader motor with trans (and PCM) in order to get the 4R75W trans as well (mine has 4R70W)?

Buy some other motor? Junkyard? Crate?

I've contacted a few people about rebuilding my exisitng motor, and one told me that considering the reason the exisitng motor failed, its block should be scrapped. Other's didn't say this, so I question its legitimacy.

Any input and suggestions appreciated.

Thanks.
