Gen 3 Hemi Swap time!!!
Way to go on the 6.1 It's the best engine for hot rodding in an old car. No VVT, MDS, variable intake, etc. Plenty good heads and aluminum intake for boost, etc. Personally, I'd go with D. Weber for the head and intake work, plus cam. He knows his stuff about these engines and can match it all up for you. Congrats on the score...
