the 392 cam will not work in your block, what you want for cheap, easy, effective is a 6.1 cam from an automatic car (manual trans cars did not have MDS)
My info tells me that NO 6.1 engines had MDS. That alone is a deal breaker. I'd like a bit more cam than a stock 5.7, something that will not throw an MIL code and not require a "tune". The assclowns in this state have cracked down on computer controlled aftermarket "tunes" even if they do not increase emissions.
