thinking of trying a 3310-2 on my 72 skylark....the engine is a stock 70 455 stage 1 with B4B, gsca headers,mallory ignition,th 400 and 3.64's.... I'm also converting to a secondary metering block with no power valve..... so where should I start with jetting.....:idea2:
3310 a 3 barrel?????:Brow: :laugh: :laugh: Actually one of the best kept speed secrets is to go thru any given holley carb and set it up exactly like they say to do it.... jetting, all the linkages adjustments , ect....and personally , if a carb has a power valve,,, I dont get rid of it.... I will make one compatible with my cam.....but I always keep it and the vac secondaries too.....the only mods that I do is jet up or down to get the right mixture, and open [ very cautiously] the idle air restrictions to lean the idle mixture,,,, and eliminate the choke assembly.....
