Rick do you have a link to your RTR with a rev limiter? When I went to your website there was no mention of a rev limiter for that distributor. That's the only reason I went with Pertronix. And yes it sucks to have to grind on a billet aluminum housing, it looks like crap but will be hidden against the head and I will polish it up.

Muscle Motors told me there's quite a bit of beef in that area of the head so I'm gonna take a little more off there too.
