What ALL of you are forgetting is when you go to a large cam you have to up the idle. My 237/242 112 idled at 950+/- 50, that idle speed with a stock stall equals the cruise control effect. SC I dont know if you know what that is but basically any time you want to hold the truck still it is hard because as soon as you let off it wants to take off because the stock stall engages very low in the rpm band whereas with a larger converter you can get away with a large cam and not have any low speed issues because it doesnt engage till 2K or more. FYI, Im running a 226/224 112 in my 420 with a stock 80e stall(2500 brake stall speed) and that is going to net me an idle somewhere near 700 which will be fine with the looser 80e stall, stock 60e stalls are around 1800 if I remember right. Remember those speeds are brake stall speeds not the speed at which they start to engage. You have one of three choices, either buy a stall to throw in so you can run a larger cam and not have any adverse low speed driveability problems, keep the stock stall and run a smaller cam, runa big cam and do 20mph without your foot on the gas. If you keep the stock stall I would go with something like mine, if you put a 3K stall in it I would go with a mid 230s cam, anything larger and the damn thing bounces around too much while you are sitting in traffic and gets annoying after a while. Again I would talk to Richard@WCCH they build these motors all day long. Just my .02 SC take it for what its worth.
