MSD6AL box compatible Distributors

I shift at 6100-6200 and trap about the same (1/4 mile, 4.10 gear, 28" slick, weight unknown guessed at 3350 with driver, [email protected] pers best).

Dyno data....long story and don't want to hijack the OP's thread. Only broke engine in on dyno but got very limited data for fun. Also got several other 408 full data sets run right around mine and full build content for them. Knowing content and numbers, actually fairly easy to spot the data in for mine. Likely torque peaks around 4600-4700 and power peaks about 5700-5800. Have shifted it as high as 6700 and it marginally slows down confirming the lower power peak rpm. (8" ATI Treemaster converter: Was supposed to flash to 4700 when I ordered it. I think engine makes more torque than I expected/communicated when I ordered hence the 5000 flash stall.)

I was just posting the mech advance curve in case anyone was considering the Proform #66990 distributor and wanted to know what they do.
