The 7.90 Sniper Heavy 3.50" is a popular heavy package choice. This combination has been refined for many years, and provides great performance with similar longevity to our 8.90 and 3.50" engines. Not only is this motor extremely quick and reliable, but it is also very easy to tune. The 42 mm Mikuni allows you to dial in idle temperatures while the engine is running, and with our Knurled Bowl Nut/Maxx Jet combination changing main jets has never been easier.

The 7.90 Heavy 3.50" uses only the best internal parts available. An ARC 1" Crankshaft w/ 3/8" Clutch Bolt Hole, ARC Rod, ARC Adjustable Flywheel, HP Custom Dyno Camshaft, 5/16" Billet Lifters, Comp Valves Springs, Titanium Valves w/ Beryllium Copper Seats, a 42 mm Mikuni Carburetor, and a 3 Stage Header allow this motor to run 7.90's at over 500 lbs.
