Really Lovin what I set off here. I have have learned alot at the same time i don't feel stuck with my 390. But I know I will have to work it out somewhat to be compatible with my set up.
Right now my 1974 250 Chevy is stock except for headers, Offy intake and HEI . Later with the 194 head (higher compression) and Lump POrting planned, plus a mild cam i am sure to have to mess with the Holley some. Who knows down the road I may wander off into insanity and finally and Turbo the thing just to make life more fun.

So I think i will stick with the 390 cfm for now, because as i see there will always be better set up. Its called "tweakin it" and thats what we do.
Now if someone would please locate me that 12 Port article on these carbs i could at least learn a few tricks?
