@86drumerboy The m37 has a mopar 360 from a 1997 dodge truck. if you could see under his hood you would think it was a factory install. if you listen in the vids you can hear him bouncing it off the rev limiter. Mark(owner of truck) is not scared of using the "skinny pedal". the big truck with the 44" boggers has a cummins 4bt and the last truck has a stroked 383 gm.
