Product Details

The MSD 8407 Cap-A-Dapt is a precision-engineered rotor adapter designed for Ford V8 applications, allowing you to use MSD's larger, high-performance distributor caps in place of the factory-style small cap. This adapter bolts directly to the existing Ford V8 distributor shaft and accepts MSD's large-diameter Pro-Cap, unlocking better spark distribution and improved ignition performance.

Key Features:

  • Enables use of MSD large-diameter distributor caps on Ford V8 distributors
  • Direct bolt-on fitment to stock Ford V8 distributor shafts
  • Compatible with MSD Pro-Cap and other large MSD distributor caps
  • Precision machined for accurate rotor phasing and reliable spark delivery
  • Durable construction built to withstand high-RPM and high-energy ignition systems
  • Ideal for use with MSD HEI-style and Pro-Billet distributor upgrades

The Cap-A-Dapt system is a simple yet effective solution for enthusiasts and racers looking to upgrade their Ford V8 ignition system without replacing the entire distributor. By stepping up to a larger cap, you gain wider terminal spacing, reduced crossfire risk, and better overall ignition reliability—especially when paired with an MSD ignition box.

Very high level of responsive customer service, wow! And the items arrived immediately, so fast I thought there might be a mistake. :D<br>thx Sean!

My first order and I must say, very impressive! Awesome prices and super-fast shipping direct from the manufacturer. Couldn't ask for more! I will return.

This was my first order with Autoplicity. Their prices were great, and the ordering process very easy. I was a little frustrated at first, as the order didn't arrive as expected. When I called, it took a little work, but I finally got the info that it was shipping from the manufacturer, and did get the tracking info. The parts arrived when tracking said it should. Would I place another order with Autoplicity? Short answer is yes!

Purchased K&N Filter. Excellent price and received filter as scheduled.
