Don't know cam grind, but definitely quite a bit of overlap, 10.2 pistons, old 340 Torker. RVMB w/o 1st gear lowland apply. Worked OK with the 3.23s I had been running, but the switch to 4.30s really made my combo work well together. Maybe not the ideal steert combo by some folks standards, but I couldn't be happier with it's street manners given my driving habits.
