I got the Crane hi-6M. I didn't realize they were so hard to find. I guess I got lucky.

I have seen many of the same ones as well. Just gotta luck in the right places. There are still many out there. I am going to use DUI/HEI and have them built with the correct advance curve and the modules will have a 6k rev limiter.

Patriot Performance has been excellent to work with. I would go with the Crance boxes if I still had my TB's. I had thought about that a while back before selling them however changed my mind I guess. Hopefully all works out.

john-
go to www.chevelles.com and do a search on the dui system. I remember seeing a lot of posts on that system. I don't know anything about it.

OK

I sold my stock hp dist as well went with all msd ,,boxes ,,rev control boxes ,,and new distributors. have had my msd boxes on now for 10 years no issues "knock on wood"
