Good time to buy ecu and coil packs and you can go fuel injection later on. Just a thought.

DUi

The old school thunderbolt works fine with rarely hearing of failures but with that said I was starting from scratch and purchased some DUI's for the simplicity and again very reliable and good for practically any NA build within reason. Many including myself have went the Daytona sensors route for reliability over over the MSD. Not to mention you can map out your timing curve to your specific build. Ideal for SC or NA and I've yet to hear of a failure. If you go MSD plan on keeping an extra ign box onboard. Plus the distributors corrode quickly unless you coat them with crc or something similar.

In a nutshell I guess it depends on what your doing or have for power and where you might plan on going in the future. DUI is hard to beat for the price, simplicity and reliability. If your looking at over 650 hp go the Daytona sensor route. Your engines will like it.

Here ya go. Btw OT ck out the old thread that recently got ttt. Good info especially for your SC builds.

i don’t think locked timing is the best option. That’s where a box like Daytona comes in handy. With delayed starting, idle stabilazation, and custom curves. Don’t think it’s necessarily a good idea to have 36° of timing coming on plane. You can get defiemiely get a better tune to the engine with a custom setup

thats why I’m advocating the Daytona’s. I’m carbbed also. They helped my idle dramatically. The idle stabilization throws timing at it as needed to keep it above a certain rpm. Fun to watch on a timing light. I think they would perfect for you. Go to their site and you can check out the software and parameters. Really cool stuff.

Are you still using the t- bolt distributors? If so and in good shape I'd use them in a heartbeat. I used them years ago on some 454-SC mega blower builds and worked flawlessly. regardless of what you choose to do with distributors the Daytona will be a great addition and much appreciated to your hawks and future SC builds. The cranes were no doubt a nice piece also however not available if I'm not mistaking. Not 100% certain but seems like I either read or heard Daytona bought out or had something to do with the crane tech. Don't quote me on that but both very reliable. I do not believe the hi-6m ign boxes are being manufactured anymore.

I dont think there is an obsession with DUI rather just an OPTION for some builds. Over the years I've seen many stock GM hei in boats. Ya not cool but true nor coastguard approved. At the very least handy for troubleshooting.

l like them because they’re simple and easy just one wire. I would like to hear about the one’s that failed.
