With those big heads that is probably a good number. Do you have a trans brake in the car or a two step? Be interesting to see what you have to do to get it to hook hard at the track.
it has a 2 step and a brake. We have another converter that’s trans brake friendly. I think it’s fairly loose. It’s a 9” and was in the car with a different engine when someone else owned it. I know the J isn’t made for the brake. That 10.18 pass was leaving off idle and it was spinning on some old DR’s. The car has been 9.20’s with a W8 motor. I think it might be currently set up too stiff for the current power level. Until we get some fresh slicks on it though I’m not really sure. I knew the J converter is a good piece so I figured it was a good starting point for a baseline.
