I’ve been trying to find info on it too, and there’s not much out there.
best I can make out from bits and pieces here and there is: 9.0:1 compression with KB hyper U piston, eagle rods, cast stroker crank 4”. Cam, roller, I guess is .501 in .513 ex with 230/234 and I believe 108. It’s lumpy sounding. Oh yah, and the magnum R/T heads.
I don’t think there are many out there as they were introduced and then discontinued not too long after that with the advent of the Hemi and all..
