Re: HEI question

Ensure any resistance wire or ballast resistor is no longer present and use 12 gauge feed wire to the HEI power connection (all the way thru from ignition sw) and ensure full 12V present.

EDIT: also, recommend look at VetteVet's posts on this thread.

Re: HEI question

I have heard they should have about a 7.5 amp fuse. Have not had one blow yet and going to step it down to 3-4 and see what happens.
