I can't make up my damn mind as to which CFM carburetor to choose for my Roadrunner.
I DO know it will be a Quick Fuel Race Q. What I don't know is which CFM.....
I have a 1974 Roadrunner..... 440ci R3 small block (yes small block) with 7000rpm shift points, 11.5 to 1 comp, INDY 360-1 rectangle port aluminum heads fully CNC ported, with 2.15 intake valves and 1.625 exhaust. These heads have been totally worked over by Ryan J. at Shady Dell Speed Shop. Intake is an INDY 360-R3 single plane. Cam is a custom Bullet roller with 262 & .680 @ .050. Rockers are T&D 1.5 rollers. Full MSD ignition, and an Areomotive Stealth 340 fuel pump. Exhaust is TTI 1-7/8 long tube headers and full TTI 3" X-pipe exhaust with Super 10 Flowmaster ear muffs and the whole works is ceramic coated.
Transmission is a TKO 600 and rear is a Dana 60 with 4.10's.
This car will be street/strip with more street than strip.
Ryan J. said if it was a strip only car I would need a 1050 and he recommended running a 950 for better street throttle response. BUT...... Don at FBO (4secondsflat.com) where I'm buying this carb, swears up and down and even sideways a little, that I shouldn't have anything bigger than an 850.
I want the throttle response but don't want to choke it down when I tach it up.
any insight on this would be greatly appreciated.
