Re: Lion Speed Head
I had number 6, 7-1 it was on a much modified A engine. .155 over bore home made alum rods 1 13/16 intake valves, Stipe cam, down draft Ford 6 carb, light flywheel. This pick up would do well over 80 miles per hour. So I can not say about a stock engine. First I noticed the head was so heavy it would stay on with out bolts, well maybe not. It never could get enough spark advance with out spark knock. Probably because the plugs were in the wrong place. I changed it out for a Brumfield 7-1 it ran much better.
