Video: Hoonigans Build 700 Horsepower LS Heart for '1955 Chevy Gasser Project!

June 5, 2018 / by Evan Perkins

Watch as Hoonigans' Jon and Brad piece together an LS shortblock with Wiseco pistons. The mill is destined for 700 horsepower duty and 9-second e.t.s in Jon’s ’55 Chevy gasser project.


The Hoonigans are hard at work on their gasser project! The car, which belongs to Jon Chase, is set to be a 9.90-second, 700 horsepower drag car and will compete in a callout match between chase and Roadkill’s Mike Finnegan. In the latest episode of “Garage Garage,” the tech and hands-on YouTube series, Hoonigan resident wrench-master “big-daddy” Brad goes over the process of building an LS engine shortblock that will take some serious twist!

The ultra-stout forged Wiseco pistons for the Gasser LS build were treated to a custom Hoonigan-treatment.

The shortblock is based on an iron LS block from Summit Racing. It was machined by Custom Performance Racing Engines (CPR) and features a K1 Technologies 4in stroke crankshaft and K1 6.125in connecting rods. Wiseco provided the pistons which are designed for forced induction and a boat-load of horsepower. They feature thickened ring lands with lateral gas ports to increase ring seal and stability under high boost and heat.

The ring package consists of a stainless steel nitrided top ring and a napier second ring to both seal combustion and control oil. Forged from 2618 aluminum and packaged with uprated wrist pins, these pistons have power-adder specific skirt shapes and additional pin clearance to maximize power capacity. Lastly, they are coated in Wiseco’s Armor Glide skirt coating to reduce friction and wear.
