Jeff and I worked a little on the JH motor yesterday and found it has poor compression on 2 cylinders, so, I'll have to re-ring it at the least. No telling what else.

However, I did notice that the car has position adjustable cam timing gears. There are marks, of course, for various timings but you can change them. Stock US timing was each one at the 100 marks. But, I can advance and retard them slightly.

Now, stock timing is to be used, but, I noticed that in the GCR if the car has adjustable gears they can be used. So, I can set it at one of the other positions? Advanced about 6 degrees would be, from my engine simulations, slightly advantageous and I can almost get that. I would think this completely legal, but I'm the newbie and cautious so I wanted to ask.

Thanks,
