HEMI Engine Packages

FHO 426 Restoration Street Hemi Package

For customers wanting an OEM stock cubic inch and appearing engine, we have a package to fit the bill. This engine is built with the same high level of machining and parts as our other larger hemi packages. We can also stroke the small bore, full water jacket block to a much larger cubic inch size for improved torque and power on the street.

Short Block- See Block Prep for machining operations.

“I bought my FHO Hemi from Tim in 2015. I can drive my 69 Road Runner anywhere, on pump gas, and then go to the track and click off 10.00@134mph quarter mile runs. It idles like a family car and makes well over 750 HP. I could not be more pleased with my FHO Hemi.”
