HEMI Engine Block Machining

Whether the block is destined for your restoration HEMI Cuda, or the foundation of a 1300hp NSS drag car, the high level of machining is the same at FHO. From initial cleaning and inspection, sonic testing, to all major CNC machining operations, nothing is left to chance.

On top of the major machining, we do all the small things that many shops miss, like chamfering bores, main caps, breaking all sharp edges, oil galley mods, tapping etc.

Bottom line, we cover all the details to make sure you receive the absolute best in block machining. Below are just some of the details we address.

“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.”
