There’s nothing wrong with getting a good steel multi feed body, but I won’t run stock dual fed bodies as I’ve had too many crack. I run a stock body with enlarged feed at 1600hp

Not many of the truck guys are pushing the cubic inch limits, a lot of the deck plate engines are 394-415 cubes.

Here is a link to the rules for the light "mix" class. In order to help grow this class we have worked with Josh Vanhorn and a few other to come up with what we could to blend the light hot farm, COTPA v8 and super naturals. We feel that the weight handicaps should allow all groups to be competitive and make for an exciting class to spectate.
Thanks, James Vannest

I like the idea of the long stroke, then just add a 0.530" deck plate and get longer rods? I don't suppose there is a way to bore out a 5.9 to fit 6.7 pistons without reducing the wall thickness too much, is there even enough material to bore it out for liners to use the 6.7 pistons?
Yes there is room but it is too thin. Would be better off getting a 6.7 if you wanted to go that

Are you allowed to decube? Most of the light hot farms don't allow this. Personally I would use 5.9 bore and block and have crank stroked to 5.25" and be right at 399".

Several ways to do it. Taller Pistons, longer rods, or deck the block...somehow you have to make up 0.080"

Std bore 6.7 is 4.210" and 5.9 stroke is 4.72" netting 394 cubic inches. Works pretty good and allows room for big valves.
