[adidasrunnerx25]

ok, so if i put a 356 engine into my 75 fuel injected beetle, does that mean that im goin to have to change my fuel pump to a mechanical one as well as buy a carbuerator? and.. is there a difference between the 356, 356a, 356b, and 356c? is one easier to put in, one more powerful, etc? thnx for all you help, everyone that i show my car to laughs at it, i cant wait to blow em all away lol. thnx
