What's in the Box

Info

The Soft Touch Rev Control, PN 8728, is designed to be used on standard points ignition or inductive ignition systems. This means that the PN 8728 can be installed on engines with a GM HEI Ignition, Ford or Chrysler electronic ignition, any standard breaker points systems or even with an MSD 5 or Blaster Ignition (non-CD ignitions). The RPM Limiter is adjusted with plug-in modules and is supplied with 6,000, 7,000 and 8,000 rpm modules. When the engine reaches your set rpm, the Soft Touch circuitry kicks in and drops the spark to certain cylinders. This rpm limiter produces very accurate and smooth, backfire-free rev limits.

  • Can be used on 4, 6 or 8-cylinder engines with inductive ignitions
  • Adjusted with plug-in modules
  • Includes 6,000, 7,000 and 8,000 rpm modules
  • No MSD ignition control box required

547-8728 Instructions (PDF)


Notes

  1. IMCA approved for use in Northern Sport Mods using a crate engine and original HEI distributor, but must be used with a 6200 chip to be legal.

This rev limiter is not compatible with any CD ignition boxes such as MSD 6 series. You will need rev limiter 5478738 if you have an MSD 6T, 6TN, or 6HVC ignition box. If you have a 6A box it will not accept any add on rev limiter.

Two suggestions, 1 we offer part #5479615 which is a 163 page book with all types of diagrams and tech notes. Second, got to MSDHELP.COM. This is a great support tech line. The instructions with part should be able to walk you through
