i decided to go ahead and buy my whole HCI setup sooner rather than later, the only part im unsure about is the carbim going to top it off with, im going with the edelbrock power package, i dont know if i should go with a 600 or 650 cfm carb

im worried that the 650 might be to much carb for my little 302.

is it a performer package or rpm package......performer package will work fine with a 600 tuned right as will the rpm set up but a 650 would work tofor the rpm but when I did a similar thing i HAD to lean out the jetting in the 650 dp I had

its the rpm kit, so i might step it up to a 650 if it will work good then, do you know what the stock size is?

i cant wait to get all this stuff done, the mustang club im in is having a weekend event at the local dragstrip in mid-augustand i want finish everything up and get it running perfect by then

stock I believe was 600..some articles waiver between 580 and 600 I go with 600 as stock as there isn't much diff between the two

proform 600 vacuum secondaries ftmfw. it will be most easily tunable carb for your setup. it may be a little more than the holleys and edlecrocks, but its SO SO SO worth it.

Stock carbs were 600cfm. I would stay with a vacumn secondary unless you have some converter/gears in it.......

i am staying with a vacuum secondary i like holleys its what i had on my '72 cutlass 442 and it was great but ive been wondering about the barry grant demon series carb

if you are automatic I'd choose vaccum secondary but fora 5 spd car I'd go mechanical...my 85 was much more responsive with the mechanical secondary vs the edelbrock weighted secondary carb set up that was on there
