I bought this '79 "with original motor" for the 2L motor to build over this winter.
But according to what I find here: http://www.mirafiori.com/faq/fiatcarb_july2004.pdf.... it's not a 2L. Casting #'s above the filter read 132A1.031.5, which makes it an 1800.

So now I'm faced with a decision: Do I look around some more for a 2L, or do I build the 1800.
I really, really wanted to build the 2L. can anyone weigh-in with an opinion why I should just build the 1800? 'cuz that's what my wife says I should do

anyone got a spare 2L they want to sell . . . cheap. ?
