Street HEMI CNC Head Porting Monthly Special

FHO 572 Street Hemi Package

The 572 has become the most popular engine produced at FHO. It offers the most bang for the buck, with improved torque and power over the smaller 528/540’s. With the added low end torque, this engine does not require steep gears or high stall torque converters to perform.

Low rpm cruising with overdrive transmissions will maximize this combination. Engines can be painted to look OEM stock, or detailed with chrome/polished aluminum for Pro-street/race appearance. The choice is yours.

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.”
Joe Segreti - FHO 572 Street Hemi
