Sportsman HYD Roller 427" (625hp)

Sportsman HYD Roller 427" (625hp)

This hydraulic roller 427" is one of our most popular engine combinations. It originally started with us doing a build very similar to this for our "shop" car years ago. We had many customers call and say they wanted this same exact combination due to its performance, low maintenance, and overall affordable price. Many hours were spent designing this combination and after many camshaft/valvetrain variations, we have a very effective combination. We build these for up to a 250 shot of nitrous and in most cars, it will run 9.80-10.20 N/A and on nitrous 8.80-8.90's. It can run on either 110 race fuel or E85 (we have proven carburetors for both).
