No to either one of the cars, i did have it on mine when i first started running it but pulled it out, when it ran like crap after setting for a while, didn't know for sure if that was the problem but it fixed it. I do have an 8lb spring on the poppet in the return line highspeed pill holder.

You got a Rat in it, do you run one or two bowls or the throttle bodys. I'm getting ready to have a nitemare, with my s/blk blown motor, i melted down a piston by not running down nozzles, now i'm going back with down nozzles and i'm sure it's going to take some working thru. I've got the K valve on it. It's Buzzard on top of a 1471 it was fast for a 358" but going back with a 383" motor.

555 with single terminator..been 7.38@1925lbs on motor,has small 335 dart heads playin with sig pics

that's quick for a 555, lot's of people make the mistake of going to big on heads and losing velocity, it sounds like you got the right combo.

Finish line temp is best at 1060-1100.Pulling shutoff to heat motor and warm up is all thats needed.
I said to idle it at half fuel . not set your barrel valve at half fuel
