Holley’s 50 State Legal Performance Two Barrel Throttle Bodies
Holley Performance Products is now producing performance two barrel throttle bodies for Chevy/GMC trucks and passenger cars.
Holley’s performance throttle bodies are a direct replacement for the O.E. units and are compatible with stock GM electronics. The enlarged throttle bores offers up to 42% more surface area over the stock TBI. This added area frees up the restriction to the engine increasing HP and torque. In a zero to 60 MPH performance test comparing a stock TBI to a Holley Performance TBI on a 5.0L equipped truck nearly a full second was shaved off the time.
Current applications available are 1985 ½-89 GM 2.8L “S” and “T” Series trucks, P/N 502-3; 1986-89 GM Truck 4.3L V-6 Engine, P/N 502-4; 1987-89 GM Truck 5.0L V-8 Engine, P/N 502-5; 1987-89 GM Truck 5.7L V-8 Engine, P/N 502-6; 1988-91 “S” and “T” Series Trucks 4.3L V-6 Engine, P/N 502-7; 1985-90 Passenger Cars 4.3L V-6 Engine, P/N 502-8; 1990-95 GM Truck 5.7L V-8 Engine, P/N 502-9.
Each two barrel throttle body kit includes the high flow throttle body, air distribution ring and installation instructions.

How To Choose A Drag Race Ignition| 12/03/2018
Drag racers rely on exotic fuels and high cylinder pressures to make huge power. High compression ratios, nitrous oxide and high boost pressures paired with alcohol, methanol or nitro make lighting the air/fuel mixture in the cylinder difficult. The immense pressures inside the combustion chamber will literally blow the spark out. This is where an MSD ignition really shines. Its ability to fire the most powerful and fastest racecars on the planet is legendary. MSD ignition systems can be basic, or advanced enough to control one-tenth of a degree of timing for one-hundredth of a second in any cylinder using individual cylinder timing.
