I really want to have a rev limiter on the new motor for my 67 GT350. I plan on using the original dual-point distributor which currently has a Pertronix unit in it. The Pertronix has worked very well - no spark problems that I can tell. So I thought about buying one of the aftermarket standalone rev limiters. Anybody ever used one?

I know that Crane's points replacement unit has a built-in rev limiter but it says that it is for a single-point distributor. I also could go with an MSD or equivalent but that starts running into some bucks (not to mention the external box).

While this response is not exactly on point, I can say that I've installed the Crane XR-i and it works well.

I have been happy with my Mallory rev-limiter.
Its built into my Hy-Fire box and is adjustable in increments of 100.
Should the motor accidently overrev it cuts out spark to random cylinders to limit the RPM.

OK, I have to ask this one. I also have the Crane XR-i,and it runs well, but where do you guys establish the red line. I hear all the references (hype) on TV about the high-reving 289. What is a realistic limit before you damage your engine. I currently have the rev limit set a 6000 RPM. Sorry to highjack your post, but it somewhat related.

What are your engine's internal components like? (forged, cast, balnced, etc.) How old (miles) is the rebuild? And how do you drive it - put-putting in overdrive, or 1/4 mile passes?

A 289 will "safely" rev higher than a 302, which in turn will do better than a 331, than a 347. GIVEN the same internals!

I would guess knowing nothing else about your car except it is 289, that 5,500 to 6,000 would be safe - if it is an occansionally used limit. If you often redline it, then drop it lower.

I've got the Pertronix stand-alone rev limiter sitting on my workbench waiting for me to install it. I think it's a fairly new product from them. I also use Pertronix ignition and it has been flawless to as high as I care to rev the engine (or a little higher...thus the reason for the rev limiter).
