MSD 8455 with steel gear

Harper · October 30th, 2009, 05:34 AM

Hello!
Can someone help me? I buy MSD Pro-Billet 8455 distributor from summit for my 5.0 95 Cobra. There was notice on the gear:
"This distributor is equipped with a steel gear. It should be used only with a billet steel camshaft (roller tappet).
All cast iron camshafts (flat tappet) must use a cast iron gear.
Bronze gears may be used with either a cast iron or billet steel camshaft."
As i know my camshaft cast iron made (flat tappet). I need to buy bronze or iron gear to use this distributor on my Cobra?
Why everywhere wrote that
"For installation, you simply remove the stock distributor and bolt the Pro-Billet MSD in place!"
Anв another question. Why bronze gear "Not intended for extended street use"?
Thank You very much!

PS Sorry for my english, I'm from Russia.

If its a 95 are you sure its flat tappet and not a roller cam?

I don't know exactly.
I find information in internet that in stock Cobra 95 5.0 camshaft iron cast made and flat tappet:
Stock Ford roller cam specs - FordMuscle.com Forums
And another information:
How to tune & modify your Ford 5.0 ... - Google Êíèãè
list 50
Can someone tell me what kind of camshaft used in stock or how I can know it?

You need not worry. Your '95 Cobra has a hydraulic ROLLER tappet camshaft so the MSD Pro-Billet distributor will drop straight into place. The stock 5.0 H.O. GT and Cobra camshafts have hardened steel gears. If you're still not sure, look at the intended applications for the MSD-8455 distributor:

MSD Ignition 8455 - MSD Pro-Billet Ready-To-Run EFI Distributors - Application - SummitRacing.com

Bronze distributor gears are softer and have a shorter lifespan so they're intended more for racing applications where the engines are frequently rebuilt.
