The 90/10s are great for weight transfer and potential air under front runners but the compression is too little imo. My 67 would be pogoing 1-3 gear shifts. I never hit the Canton pan or Crites tubes but it must have been very close. I switched to Viking DAs on the front. Extension is nearly the same, (still tuning), but the controlled compression has car much more stable through upshifts.

On the footprint, if you make the decision to get a 10.5 tire under there the extra total 3” +/- of rubber will make a profound difference.

Been running an NGK range 8 for the last two seasons. Engine is burning oil but still running well, frequent plug changes a must. It should come apart but finances dictate otherwise at this time. Which direction, ( plug heat range), might I try?

Thanks.

That makes two of us Doug. I’ll see if I can find out anything useful.

Hey Doug,
I have a used set of Comp 930-16 springs. (1.550)

They were set up at 330/120 with a hydro roller when I used them.

Harry, how does the back side of number four intake valve look compared to the others? La Brea like?

Get stocked on utility blades for your gasket making class.

My optimism has borne out.
Thanks Doug!

Good price
