I think it is that cam. Mine is the 402 435 Horse motor which uses the same cam. Probably the extra horse because of the extra cubes from the 4"stroke and the big valve r/t heads. Just making changes on the whole thing now, someone put it together and never used it. It had a 3800 tci stall in on a full manual reverse pattern tci valve body trans. I found it to be way to much converter. Because of the gobs of torque it has I’m now aiming for anything between 2500-3000. I’m have a normal pattern regular valve bodied 727 transmission being built built with a trans go tf-2 kit for it now.
