Will Stevenson is preparing to get back at it after a time off from racing with a new engine from Steve Morris and some chassis updates from longtime chassis man Dan Neumann, which include a new Racecraft housing, coil over conversion with AFCO Big Gun shocks, larger wheel tubs and a removable nose for ease of maintenance. The engine itself is a 615-inch big block Chevy using Will’s Dart 18-degree Big Chief heads and F3-R 139 ProCharger for now, with plans to move to the new, more efficient F3-R 136. With the ProVolute bell and CNC internals the mill produced 2,491 peak horsepower and 1952 ft-lbs of torque using Q16 fuel along with an intercooler. Steve Morris has done extensive testing using this engine with various superchargers over the past couple of weeks with excellent results, showing back-to-back runs after performing internal modifications to various units. Check the thread over at Yellowbullet.com to join the discussion.
The Racecraft-sourced 9-inch housing was narrowed five inches to fit the 15 x 12 double bead lock Mickey Thompson wheels and stripped down of brackets, new pieces were fabricated in house for the lower control arms, panhard bar and shocks due to the custom placement. MAC-FAB handled the bead lock conversion. The lower arms were moved inboard about an inch for tire clearance and the shocks now sit in front of the axle as opposed to the stock location used before. There's also another set of holes on the chassis side for more adjustment and a lower ride height as well as reinforcement in that area. Photo courtesy Dan Neumann Race Cars.
A new round tube shock cross member was installed along with enclosures in the body featuring a removable top to easily set the shock adjustments and access the bolts as needed. Additional components for the car include a new Double AA Performance K-member, A-arms, limiters, Strange double adjustable front struts, Strange brakes, and Racecraft Caster/Camber plates and spindles, with Will taking care of the installation at his home shop. Like many racers, he prefers to do all the work he can to the car himself.
When all this is finished and Stevenson receives the new engine from Steve Morris it will be set between the frame rails and he’ll will begin the final assembly with the goal of racing at the Yellow Bullet Nationals this September.
These photos of the car shows the modifications to fit the shocks, the new tubs and sheet metal around that area, in and under the car which still retains much of the original floor as possible. Photos courtesy Dan Neumann Race Cars.
