For a crisper, smoother running engine, replace your stock HEI module with the Dyna-Mod. The Dyna-Mod has more "electronic dwell" in it to provide more coil saturation time. The additional saturation time allows the coil to produce a more intense spark. Our Street/Strip and Racing D.U.I. Distributors require our 4-pin Dyna-Mod.
Part #000222 (74-Present w/o computer) $49.00
The 7 pin Dyna-Mod is designed with more electronic dwell for your computer controlled HEI. With the increased dwell time, the coil will saturate longer to create a more intense spark. Quicker starting, better throttle response and more low end power will be gained by replacing your stock module with the 7 pin Dyna-Mod.
Part #000333 (81-90 Chevrolet V8 Computer-controlled HEI) $55.00
The 8 pin Dyna-Mod was designed for computer controlled GM vehicles using the external coil. It is designed like our 4 and 7 pin modules with the increased dwell time for better combustion. Improve the performance of your car or truck by replacing the stock module with the 8 pin Dyna-Mod.
