Our rules state that must use stock HEI or point dist. What do you recomend to run on a 355 flattop engine to run in the 6000 rpm range? i.e. gm dist with ? pickup, module and coil or aftermarket dist that is stock appearing.

thanks for any help

I would use the stock HEI. However you should replace the coil and module with aftermarket parts. (MSD, Accel, etc) The stock pieces arent good over 3500 to 4000 RPM

My advice would depend on your budget. Chief4car touched on the minimum upgrade needed. You probably also should keep an identical spare, with the stock pieces. If the price of the stock appearing setup does not severely dent your wallet, I would go that route. I know a lot of guys run that stock stuff, but I also see a lot of guys thrashing to replace it at the track. Keep it in mind, even if you go the cheap route.

we run a DUI on our 355, and have never had a problem this year...we pull about 6300 to 6500 rpm, depending on track and gears

Try a supercoil with a stock HEI, then run an MSD Box into the HEI if they allow for alternate pickups or modules with a stock appearing distributor. Take care of everything.

I run a stock type HEI locked up with a DUI cap, module and coil. Recently, I wired it up for 18 volts using a motorcycle battery as shown by Sleepy Gomez in Circle Track magazine. The 18 volts made quite a difference and it only cost $10 - Thanks Sleepy.

Okay I am looking at some of these modifications in the race shop the other day and was wondering - When I do select the right combo for my ride how is the tech guy going to know if it is stock OEM or not? Looks Like I can peal off that little label and no one will be none the wiser?
What parts look the most stock and have the lowest detection rates?

thats just what i did dirt i took the sticker off the coil and you couldn't tell the msd from the one that came out of it .the same with the nodual msd mods i have seen look like a circit board so thats hard to hide but more than likley a tech guy will not take a dist and look inside these rules are basicly set up so we don't use the external boxes and such as long as it looks like nothing has been done to it they have no reason to look unless they want to be a jerk

the stock hei will work fine. get a new coil and mod. so you don't end up with the older gm mod. (it was junk) the new mods. will work graet at that rpm. i run msd mod. and coil. if your budget allows it great if not the stock stuff works fine.
