Like Mudmissile said definate et diff easy.15-.2 seccond diff. If the class you run your cuts in allows scoops,and other people in the class are running scoops you are definately leaving something on the table.Diggers take quite a bit of Hp to make work well but will put a big on your face.Gary Heusted back in the early 90's here in MI use to run I think it was a 12 scoop 33"digger on his 421 sbc jeep all motor. that jeep was amazing 2.6-2.8 150' all day long Thirteen or so years ago.

you might want to try to stay smaller to match the size of the cuts your running now. maybe a 32x14x15 that would be around the same size as your cuts.,with 10 or maybe 12 paddles, wouldn't get anymore than that. ran that size on a full size with a small block, hooked good, had to start buying better rear end parts, stock stuff won't hold up if it hooks..
