Used the Crane unit in three installations as of now and other than a little "fitting" of the breaker plates to make them move properly, they work nicely. Crane does state that a little work may need to be done to fit the parts so expect this.
If you don't use a vacuum advance, fitting of the parts would not be necessary.
Crane does include a rev limiter.
I have not used a Pertronix unit.

i've used both and neither have yet to fail on me. The crane unit does have a built-in rev limiter, which is neat, but like boss68 said, there is a fitment issue you'll have to get past to install it into the stock distributor. the pertronix unit bolts right in (as does the pertronix II, which is the "twice as much" price). the pertronix I unit is about the same price as the crane, but without the rev limiter....

 

I picked up the crane unit, pertronix was $107.00 & the crane was $60.00. I did some reading online and crane seemed like the better choice. The price was a bonus.

Thanks for the input

 

Perktronics vs crane

What the guys said about the two units are right. I have the Crane unit and what I like about it is that I have the old points and condenser in the trunk and if the Crane unit ever fails in nowhere land I can just reinstall the points and condenser and be on my way. You can't do that with the Perk unit.

 

I haven't used the Crane, but I absoluely love my pertronix. If you have clearance issues a possible solution is to get an air cleaner off a late 70s passenger car with the offset air cleaner. They made them with a dogleg bolt so they sit farther forward on the carb to clear HEIs.

 

Here in BC the insurance provider is really strict when they issue collector plates, if I were ever in an accident and I had anything non stock in appearance on the car they would void my coverage, I had to submit 10 photo's of the car when I applied for the plates so unfortunatley I have to stick with the original air cleaner.
