RE: Spark plug question

[Paul Lennemann <pjlenn@xxxxxxxxx>]

Don D. recommended an Autolite 2974 as a replacement (for 85's I think). 
 I ran a set for awhile.  It is a small lawnmower style plug so I had to 
cut down the boots on my plug wires or they would not go on all the way. 
 I could see how they would work well with some headers due to the small 
size.
