DUI Distributor Roll Pin
Ok guys, seasons over and my friend pulled the camshaft out of his 454 to make a small upgrade, I don't really know the specs of the new one and it really doesn't matter for this post.
He got the cam and it came with a distributor gear, when we went to install the gear on the DUI we knocked the old roll pin out and went to press it back in with the new gear and it didn't go in smooth, we pulled it back apart and to my surprise, DUI uses a 13/64th's??? roll pin diameter (measured the hole about .202"), the distributor gear that cam with the cam is 3/16, just like every other distributor I've ever dealt with. Why in the world would they do this? a) it's impossible to find that size and b) why on earth would you do anything but standard (maybe they want you to buy the gear from them???)? They are sending him a new roll pin and I'm having a machine shop drill out the gear so it's not really any big deal. I should have measured, but hey that's life. We can't be the only ones to ever run across this. What gives? |
What does DUI say ??

DUI is sending us a new Roll pin, they gave no reason for using a stupid size, but did say there gears would work for $75...a-holes... I had our metal shop at work drill out the gear to match...
It is funny about the Chinese comments now, when this was the recommended distributor when he asked on this site before (not sure what his screen name is on here) :) -- All we know is a stand alone MSD was looking pretty good once we found that out...it's just a 454/330 in a mid-80's formula so it's not like he needed something hi-po. Oh well, I guess the lesson is, measure because you never know when you run into Chinese garbage I guess :lolhit: |
