That depends on what plug wire diameter they used in the early 70s funny cars and dragsters.... Was it 6mm, 7mm or 8mm plug wires???..?
Just take those^^^^diameters and divide by 16.... The scale your working with and you'll have your answers...
I think it was MPC that had a Crondeck (sp) timer christmas tree in one of the early 70s annual kits... I just don't remember which one.... Anyone here know???.... Pictures would be great if possible... Thanks guys!....
The company I work for cast the prototype aluminum intake manifolds for these and I did the machine work on those... I have pictures of those, but I'm not allowed to post them... ?
