Any jetting suggestions for a 426 with a wiseco 11:1 and a hotcam stage 2 (new stage 3). Also some porting and polishing. I am using dynojets.

I'm located in michigan, my 416 with 10.8:1 piston, stage I hotcam and mods in my sig runs great using a dynojet 170 main, 42 pilot and needle on the 3rd groove

Thats to rich for me! I got a 160 in there now and it seems too rich. Still have the stock pilot also.

Im at 300 ft and Im running 40 pilot 155 main... its spot on. However I have just porting not polished.
