In January 2018 I decided I needed to build the first fully water jacketed all billet engine that could utilize all the rock solid proven parts of the 481X! After 1 1/2 years of development I am proud to release the SMX engine. 

This Engine uses all of the 481X common parts like valve train, cranks, sleeves, cams, lifters, intakes, gear drives, everything, all the readily available parts the ProMod guys use and have on hand.

You must use our block and heads as a package because the head studs have been moved in comparison to a 481x to make space for the water jackets.

1) Blocks and heads available for your engine builder to finish

2) Complete Super Charged engine packages available 

3) Complete Turbo Charged engine packages available 

4) N/A and N2O combos also available
