the artisan

I have both a blown chevy 526 cu in w/Kobelco 1471 Superman and Veney headed 526 cu in hemi w/Littlefield LB21. When the motor is on the transbrake at starting line, the front cylinders 1 & 2 are down 300 to 400 degrees from the others. It takes 1 to 1-1/2 seconds to get the temperatures to the other cylinders. I feel like I am losing ET. The port nozzles at the finish line are perfect. Question: have any racers had this problem and found a fix? I have moved the blower back 5 inches but this didn't help the front cold cylinders. Any help would be appreciated.

 

Are you bleeding off fuel on the 2 step? What is the fuel flow on the 2 step

 

not running 2 step. running air throttle at 4000 starting line rpm. don't know what fuel flow is at starting line.

 

Add a couple degrees of timing to 1&2 on the launch
