440 and supercharging
there are real blower intakes available for big block mopars,,
BDS,,, hampton,,big als toy box,,,if you look around you can find them used,usualy around 300.00 bucks,,,
probably a better deal to just get a new blower with wll the correct gas engine sutff verses the fee to rebuild,,and convert to a gas street engine,,
plus the blower off the diesel wont look as pretty as a new case,,i have a real blower off of a GMC diesel,, dated 1965 and my case isnt as nice looking as a new one,,, but i keep it polished,,,and most people dont realize it,, cause they are just amazed at a blower car at a show or on the street,,,
but rebuilding and converting it can be done,,,several places to get the parts or too have it done,,
