34 X 9.50 Super Swamper TSL's for tires (Maybe Boggers), spool rear(weld), Lock-right front, mild 2-3" lift, you will do well.
I ran a similar setup in the 80's and did very well against V6's in the 38" and smaller 4/6 Cylinder class in the local mud-bogs in upstate New York. Always placed in thetop 3 and one several events.
