Just a little motor upgrade. Changing; crank, rods, pistons and cam. While in it going to upgrade to .904 lifters and 55mm cam. Upgrading so it can take a little more nitrous. Going to lighten the truck 60 to 70lbs and make a longer wheelie bar. Bad this is I'm still racing. So I don't have much time to get it all done. January and part of February is all the off season we have around here.
