Which plug wires do I use for a BBC w/Dynomax headers. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Pretty sure I'm going with MSD 8.5's but I don't know which ones to get. They have under headers, above headers, 90deg, and multi angle. I've got an stock HEI. I don't care if they go above or below the headers. I just want them away from the header tubes (I hear the rear tube is the worst).

HEY 70 JIMMY IVE GOT DYNOMAX HEADERS ON MY BIG BLOCK ALSO AND I WENT WITH THE UNDER HEADER TYPE(MSD 8.5) BUT THEY SEEM A LITTLE SHORT. IF I HAD TO DO IT AGAIN I WOULD PROBABLY GO WITH THE 45 DEGREE ANGLE OVER THE HEADERS TYPE JUST MY .02 WORTH HOPE THIS HELPS.

On mine I just used a set of Accel wires with straight boots and they've been working fine for me.

(I forgot to add that I have HEI)
