I run Accel 300+ wires. The problem with an automotive set is one of the plug wires will wind up being short. I had to return one to Accel and they exchanged it for a longer one N/C. If you get a marine set the wires should be longer. I have been looking and DUI distributors and I noticed they have a nice set of wires. http://www.tpmarine.com/index.asp?Pa...S&Category=196

I've been running the MSD 31489 (pretty certain that's the number, but I can check tommorow) and they fit great and I have had zero problems. I'd call Tech support to see if it is the same for your application. My engines are Gen 6 502's.

msd's seem to stay on better to me..you have to look carefully to find the set that runs low and has 90 deg ends....well with my headers anyway...Rob
