After picking up the controversial win in Pro 315 at Huntsville’s Radial Fest last month, Eddie Harrison and his crew arrived back home with a damaged engine. With running a best-of 4.13 at the event, Harrison says it was harder and harder to get the engine up on boost, and the performance was down, so he knew it was a tad hurt. After getting it back home and torn apart, it was discovered the engine had spun a bearing.

For a background on the car, Harrison bought the car with it already built by Vanishing Point Race Cars. However, Harrison had Straight Line Chassis’ Jimmy Blackmon go over the car, front-halfing it, and revising some of the rear suspension setup. Blackmon did much more to the car, as well. He built the engine using an Alan Johnson billet block, heads, and intake. ProLine Racing did some machine work on the 481X combination, and supplied the engine’s camshaft, too.
Blackmon also tunes the car via a Big Stuff3 engine management system, AMS 2000 boost controller, and Billet Atomizers injectors. Harrison’s power adder of choice are a pair Precision 94mm turbochargers, which their installation was also handled by Blackmon, who did the wiring, plumbing, and the car’s headers. By Duck’s race in the fall, the plan is to have a pair of 98mm turbochargers on it.
Behind the engine is a Keith Neal two-speed Turbo 400 with a 1.48 gear set and ProTorque converter, and a Mark Williams nine-inch rear. Part of the front end work done by Straight Line Chassis was converting the car to a strut-type arrangement with Santuff struts. Out back, the nine-inch is suspended by Mark Menscher shocks. Harrison ran Menscher shocks previously and when Harrison needed new ones, he traded out the old set straight up.
As for the hurt powerplant, “We just got it back together last night,” Harrison told us late last week. Therefore, it’s almost time to go racing again. Harrison plans to race next weekend, June 26th and 27th, at the Baddest of Da Badd event at Carolina Dragway in Aiken, South Carolina. After that he might hit up the Yellow Bullet Nationals. If not, they’ll look at making an NMCA race and entering the Radial Wars class at either Joliet or Norwalk.
