HEI conversion question

Sorry Dart, what I said is very true & 100% correct. The pick up wires can be several feet long, as long as they are kept isolated from magnetic fields, as I described in post 32. You just repeat in post 33 many of the things I already noted in post 32.
I have on numerous cars installed elec ign systems using magnetic p/ups. One car I did about 10 yrs ago has a rear mount dist & the module is at the front of the car, behind the battery, to keep it cool. P/up wires are twisted, laid along the inner fender, several feet long, zero problems.
MSD say it is OK to lengthen the wires for it's ign boxes.
