Hi Mark. My points distributor was already converted to a Crane XR-i & used with a digital HI-6 box when I bought the car, but never had a problem with that setup. With turbo I run MSD pro-billet distributor and MSD digital 7531 box, which I really like. Neither setup went above 6700 rpm however so not familiar with how well either would work approaching 8000 rpms, but should be capable without need for crank trigger. I had issues with my points in the 80's & went to HEI to solve the problem. I was using the cheap points which may have been my problem, but I feel there is a reason they are all but extinct, esp. for high perf. applications. I feel why risk problems using something that MAY work when there is an option that WILL work. Not saying it CAN'T be done, that's just the route I'd go. Hope this helps with what you were looking for, & feel free to contact me with any other questions & I'll help if I can. Also, let me know what you decide & I'll watch for updates.
