This is the most powerful, naturally aspirated, pump gas, hydraulic roller, true street engine we have to offer. Everything about this engine is just epic. The cubic inch, the cylinder heads, the camshaft, everything is turned up to the max, yet this beast still makes peak power under 6,000rpm, has a very street friendly valve train and runs great on pump gas. It truly is a B.M.F'r.
Like all Smeding Performance engines it is backed by our industry leading 3 year/unlimited mile warranty.
