i just looked at my rules. they changed the rules to 380 cfm max and 1.25 venturie. i don't think 1.33 will work for me.

this is probably why there are 2 bbl carb restrictions... this was outlawed decades ago... its a R6425
i will have to repost the picture.. sorry..
there was NO OEM application on this carb... it was strictly for circle track racing..
for those reading.. its an annular discharge venturi.. without any booster venturi's.. just a ring of feed holes around the narrowest part of the venturi bore.. unlike any other holley i have ever seen... all have some kind of dogleg booster..
