Cool. Thanks for the info. I'm wondering if anybody has an F engine carb, if they could look to see if there are numbers stamped on the venturis, as shown in this thread:
I am expecting to see 28 primary, 31 secondary. If that's true, then those numbers would "flange up" to the research/reading I've done.
EDIT: Matt, what kind of MPG are you getting? What performance improvements did you see?
Ricardo, are you still jetted to these settings? IIRC, you went from a F block to the F1.5 block when you did the latest rebuild right? And you say the F1.5 uses the same 2bbl carb the F block does?
EDIT AGAIN: I think I found my answer about 38/38 being on F engines:
