List Hunter—Daddy Dave Swaps to Pro Line Racing 481X and ProCharger F-3R-136 | Presented by Nitto Tire


Discovery Channel’s popular Street Outlaws is a realty show that utilizes a unique method for crowning the baddest street racecar in the land. Racers move up the Top Ten List by beating the person in front of them. For “Daddy Dave” Comstock, he sat at the top of the list a few times over the past ten seasons of the popular show. With many of his competitors resorting to twin turbochargers and nitrous engines with displacements north of 900ci, it was time for Daddy Dave to get an upgrade in power.

In the world of outlaw racing, the term “too much” is rarely uttered, especially when it is applied to horsepower. The conventional big-block Chevy that served him well over the past few seasons has been retired. In its place is a Pro Line Racing 481X that Daddy Dave purchased from noted West Coast Pro Mod racer Andrew Berry. Pro Line Racing recently freshened the engine and modified it for a new life as a supercharged combo with a new camshaft design. Boost will be provided from a new ProCharger F-3R-136 supercharger, a much bigger unit than his trusty F-1X-12R blower. Power levels are estimated to be above 3,000hp once the new 481X is running at its full potential.

Larson Race Cars is responsible for the winter updates to Goliath 2.0, Daddy Dave’s 1963 Chevy Nova. The famed chassis shop fit the new engine between the frame rails, built the motor plates, modified the front-end for a new fuel cell, and upgraded the chassis to be stiffer in order to handle the 3,000-plus horsepower. Also new is a set of zoomie headers, designed to expel the spent gases and wake up the neighbors in a two-mile radius. Goliath 2.0 is currently getting a FuelTech USA FT600 engine management and fresh wiring system.

Daddy Dave’s old conventional big-block Chevy/ProCharger F-1X-12R combination made 2,500hp and ran 4.20s at Lights Out 8 on Mickey Thompson ET Street Pro 315 radials.
