514ci Supercharged Big-Block Ford
Scott Wahlstrom, Motor State Distributing, Watervliet, MI
Scott Wahlstrom has been waiting for years to spin his tires and listen to blower whine. His engine was built in 1999, and he just got the car together and drove it for the first time in the summer of 2005. He had the simple plan of building a big-block for his '70 Mustang for a road trip from Detroit to California. He enlisted the help of engine builder Ken Messing, from Messing Automotive Machine, who put a 4.150-inch forged twister from Crankshaft Specialists into a 0.080-over 460 with a set of Blue Thunder heads and shrink-wrapped it for delivery. It sat for a year before finally making it into the car, where it sat for another three. Finally Scott's friends Allan Wyant and Chris Burgo intervened and got the car on the road. By then, gas was $3.20 per gallon but Scott didn't care. He drives it, lurching blower and all, as much as he can. He'll never install a hood because he fears it will silence the engine's big statement.
A. Belt Guard This is actually a professional drag-racing component. On an Alcohol or Top Fuel dragster, it keeps the belt from flinging off into oblivion and provides starter alignment for a handheld starter.
B. Motor Plate The All Star Performance engine plate is a private label from the product line.
C. Ignition Scott uses a Mallory distributor and coil. Yes, you have to pull the supercharger off to service the ignition.
D. Blower The Kobelco 14-71 is a monster blower that is usually seen on Top Fuel cars and some Pro Mods. It's underdriven so Scott can drive the car on the street.
E. Manifold The dedicated blower manifold is from Blue Thunder.
F. Bits That is an Enderle dual-carb linkage kit.
G. Carbs The most modern pieces on the engine are the 750-cfm Demon boost-referenced carbs with Idle-Eze.
H. Driveable? Scott says, "When you come to a light, it starts to surge, which I think is kind of cool so I am not going to tune it out."
I. On the Firewall Scott talked to John Denich at Classic Performance Products, and they came up with this master and remote reservoir. Now you can buy it as an over-the-counter kit.
J. Rotator The setup uses a set of 6.8-inch Eagle ESP rods with a custom Wiseco piston with 1.375 inches of compression height. The 514 has an 8.0:1 compression ratio with the 100cc heads.
K. Pipes The Ford uses big-block Chevy headers that have 2-inch primaries with a 3.5-inch collector that Scott describes as a "puzzle." The pipes had to be chopped and welded together to fit within the stock engine bay and frame dimensions.
L. Cylinder Heads These are Blue Thunder aluminum heads that eliminate the exhaust restriction by using big-block Chevy exhaust ports that are raised 31/44 inch and extended 1/2 inch past the lower head bolts.
M. Water Pump Look closely and you'll notice the Edelbrock pump is actually divorced from the front of the engine. It's driven by the crank by a separate belt and is bolted to the engine plate.
