    Default SST60 CaRbIeS

    The part #433457 from what I have seen is SST60 carbs only. Question is what is the difference in those carbs and some 75 Stinger Big Bore carbs?? What is the venturi diameter?

    What carbs could I use to build my 56 ci? If I wanted to make her scream?

    the big stinger carbs (1 1/2") have 3 jets, high , low and mid. sst 60 carbs have high and low speed only. i think i'd try some 2" 2BBL carbs.

    2" 2BBL ? Do you mean 2 barrel like the 31m carbs?

    The finger ports come with the SST60 pistons from seaway? or do I have to make them myself?

    SST60 did not have finger ports out of the box, they would need to be installed on the piston and the cyl wall, the piston is easy enuff, you can do the cyl wall by hand but the best ones ive ever had were done by machine. not all 2bbl carbs are the same, Mod50 2bbls are setup to feed 1 cyl, reg v4 v6 2bbls are for 1 cyl each side.

    Could you post a picture of what the finger ports look like on the piston? Or do you have any you would sell? I get a basic understanding of what they look like.. to copy I would be good. Or am I making it more complicated than it really is? lol

    this is a WISECO flat top Mod50 piston, 56 would not have the big transfer hole, the two small holes are finger port transfer holes............
