My 408C has 1500 miles on it. It has a Comp solid roller cam. I has an MSD dist with a bronze gear. After 1500 miles the gear shows a lot of wear. Is this normal or is something wrong??

Ray,I've got to pull mine and look at it. Maybe tomorrow. I've heard it's fairly mormal for a solid roller cam to be hard on the bronze gears, but that's better than eating up the cam's gear. H.D. oil pumps and high oil pressure create even more load on the dist gear and wear it faster. SteveW

Hey Ray, I think I saw some type of composite (?) dist gear in the Summit catalog, made by Comp and listed for SBC's ... maybe worth a call to Comp to see if they're available for Fords yet. They're advertised as a durable, long lasting alternative to the typical wear of bronze gears.------------------ 1965 GT coupe, 333ci aluminum headed/solid cammed stroker, four speed, 3.70:1 9" All Blue Oval, no blue bottle http://mustangsandmore.50megs.com/V8Thumper.html

It's normal Ray. YOu just have to keep an eye on it. I replace MM's gear once a year and I don't quite put 1500 miles on it. We change Tony's about once every two years or 400 runs.(hydro roller and 2000 less RPM) Good synthetic oil helps. ------------------ Alex Denysenko Co-Administrator and Moderator NHRA/IHRA/SRA member and licensed Superstock driver MCA member# 53321 NHRA and IHRA SS/LA National Record Holder '00,'01,'02,&'03 Fleet of FoMoCo products including 88 ASC McLaren Mustang #28 Professional Manwhore The Barry of BarrysGrrl Quote #1: "I never met a magazine mechanic I liked."

Well, Here in a couple months I will tell you how the steel gear form Crane works. I have one sitting in a box to be installed here in a couple weeks. That is going to be my choice for the dizzy gear.------------------ Larry No fast Fords at this time but one fine cruising 96 F350 CC DRW Power Strokin diesel.

Ray,I have never ran a roller cam but I have ran a solid in my .030 over 351w with .560 lift.I ran it on the strip for 2 years bracket racing put a lot of runs on it.A friend was having trouble with distributor gear wear,he was running a non roller hyd and an MSD,same part # as mine.So I pulled mine out and sure enough mine was looking pretty ugly too.I sent it back to MSD got it fixed no charge.It turns out the dist would hardly go into the engine so I pulled the pan off to check the alignment of the oil pump drive...it was so bound up it was no wonder the drive gear went to he$$.Turns out the new FORD MOTORSPORT OIL PUMP DRIVE WAS BENT from the start.I bought a new one from FORD POWER PARTS and never had another problem since and am still running the same high vol.MELLING pump and .560 lift cam since 1997...no more F.M.S. oil pump drives for me or my buddy. ------------------ This is FORD COUNTRY, where on a quiet night, you can here a chevy rusting

Dan, Everytime I change the oil I look at it in the light. It has a nice metallic paint look in the right light. SteveW

I ran my first bronze gear for 4 years before I replaced it. I checked it every winter when the motor was apart, and it always showed minimal wear. I finally changed it "just because". It didn't look any different that year than the previous years, I just felt it was time. I still carry that gear as a spare. Maybe I'm not picky enough?

Here is how I found the problem. I had a miss between 2600 and 3200 rpm. The miss was there in all four gears and even at wide open throttle. Cruising on the highway at 3000 rpms was horrible. We chase it, tried known good coil, MSD box, and wires. This may sound far fected but here goes. The gear was causing a vibration in the dist and causing the weights to fling out and back between 2600-3200 rpm. We lock the dist and set it a 38 degrees and no more miss. I have a new gear coming on Tues and we are going to unlock the weights and see. I am waiting for a reply from Comp Cams to see if the Crane steel gear will be compatable with their cams dist gears material. RAY
