A little advice please

I figure it's my car, money, and imagination so why not. I am putting in a Cummins to one make it reliable and two so that it will have power and mpg.

reliable - yes but expensive when things go wrong
power - not out of a stock 5.9 cummins, I'd be lucky to outrun a yugo, unless it was uphill while towing :D
mpg - is pretty good, certianly better than a big block

like you said it's your money
