Q & A

What's in the Box

Top off your Ford or GM Ignition system with these great new replacement coils. The Blaster TFI and GM Coils have MSD performance in factory style housings!MSD designed these Coils by combining our Blaster Coil experience with E-core coil efficiency. Each coil has a unique turns ratio plus there is lower primary resistance than the stock coil. This all amounts to a bolt-in replacement coil that produces more output voltage. The Coils will work with stock ignition systems as well as MSD equipped cars and trucks.

  • Direct performance replacement for Ford TFI coil
  • 85:1 turns ratio and lower primary resistance produce high voltage output
  • Works with stock ignition as well as MSD Ignitions
  • CARB E.O. Approved

MSD 85551 Chevy Billet Distributor
(Part #54785551)

You cant go wrong with the best selling MSD Billet Distributor! The housing is machined from a billet of 6061-T6 aluminum on a state-of-the-art CNC machine producing exact tolerances. For high rpm stability, a .500” steel shaft is supported by a sealed ball bearing and a long sintered bushing. This shaft also receives a QPQ coating for friction reduction and resistance to corrosion. A precision machined reluctor is attached to the shaft which triggers the magnetic pick-up mounted in the housing. This high output magnetic pick-up is the most accurate way to trigger your ignition. Plus, with no moving parts to wear or adjust, the pick-up is maintenance free! Just above the pick-up is MSD’s adjustable mechanical advance assembly. Different springs and stop bushings are supplied so you can tune an advance curve to match your application.

Fits Small Block or Big Block Chevy V8.

MSD 8361 Billet Chevy Distributor with Vacuum Advance
(Part #5478361)

The Street Pro-Billet is a popular route for people looking for proven race performance for their street cars. A vacuum advance canister provides economy and the proven MSD mechanical advance gives you the opportunity to dial-in a timing curve to fit your needs. Inside, an oversized steel shaft is QPQ-coated for low friction and rides in a sealed ball bearing at the top of the distributor with an extra-long sintered bushing at the bottom. This combination keeps the shaft steady creating accurate spark delivery at any rpm. The Street Pro-Billet relies on a magnetic pick-up to trigger the MSD Ignition Control which delivers the powerful sparks to the coil. This pick-up is extremely accurate and never needs adjusting.
