Hi All,
Just purchased a Proform 1050 cfm carb for my 496" (383 stroker) and I am curious if anyone has this carb on a similar engine as described below and if so where have you ended up with your jet sizes?
This engine is in my '69 Coronet resto-mod street cruiser. I doubt seriously it will ever see a race track.
The carb was shipped with 87.5 primary and 91 secondary and a 4.5 PV in primary, none in secondary.
440 Source stroker kit
10.5 comp
Stealth CNC ported heads
Mopar M1 intake
Howards roller 565/565, 241/247 @ .050, 110 LSA
HS 1.5 rockers
MSD ignition
Hooker long tubes (1-3/4")
3,000 stall converter
3:55 gear
If this was a pair of 1050 Dominators on a 468" BBC I could tell you just what you need to be in the ballpark but I don't have much experience with the single carb setups.
I know how to tune it, I am just asking if it's close in its as-shipped state.
Thanks for your input.
Mike
