just done a tune up on my 416. rpm heads air gap intake 10.03- 1 compression. cam is 543 lift dur at 50 is 256 lobe sep is 110 and 106.1. msd 6al and a msd dist.the carb is a 950hp primary jets are76 and sec jets are 75. air bleeds are 74 idle and 32 primary.the car is working good I just want to clean my idle up a bit she burns the eyes a bit at idle how much bigger air bleeds should I try. go up to 76 or go up higher. what are u guys running for air bleeds in your strokers with the 950 hp

76 jets in front...75 in rear...with or with out power valves?

I would go to 76 and try it don't go to lean at once .

 

[jimjimjimmy]

with power valves Lofgren auto specialty built the carb and dyno tuned it . it works good quick and crisp just a little strong at idle

I normally go .003 at a time on idle air bleeds, so if you got .074's try some .077's.
Is this a 4 corner idle carb? And where are your floats set at? Floats may be a tad high.

yes it is a 4 corner idle and I put the 76 air bleeds in but now my fuel pump is taking a dump I only have a little over 3.5 psi fuel pressure so no sense in any more tuneing until I get a new pump.funny things happen with low fuel pressure.
