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 together because I have moved 1 bolt hole from the common 481X

Rock solid, bullet proof and Proven now with water jackets for all other applications that need water cooling! 

(Below is NOT the final cooling passages)

1) Engine Builder kits available 

2) Complete Super Charged engine packages available 

3) Complete Turbo Charged engine packages available
