Have AJ run the numbers for you now that you know your compression, 308 heads which should have slightly smaller chambers than X or J
he'll have to add 10-12 degrees to the MOPAR timing to make his computer program work right maybe even close to 20 degrees to go from .008 to .004
update figure 16-18 degrees from MP to .004 so almost a 290 cam the way Crane measures cams
As said above not much to do if FT pistons way down the hole
maybe not this thread but BTW the 4 eyebrow Pistons are so they do not have to make Lefts and Rights
