Anybody ever use a Holley 4175?
I just bought a Holley 4175 Mechanical Secondary Spreadbore Double Pumper (not a classic DP), the Q-Junk is out. Any body ever bought one, are they easy to tune, I plan on using it on the street and strip. Not a daily driver.
I am looking for advice on power valve, jets, and metering rods to use. My 355 has;
Roller 1.6 to 1 rockers
Dual valve springs
2.02/1.60 valves in a set of 882 heads w/no porting
Stealth intake
9.3 to 1 pistons
CompCam 280H (230 at .050, & .512 lift w/1.6 rockers)
TH700R4 with a 2500 rpm stall speed TC
3:73 rear end
Any help would be great. The carb I got is new in box.
