Thermoquad issue

AJ, you may be right about the 38* timing being some indication of combustion efficiency. The weak spot in my "formula" isn't the heads (X-heads ported and chamber work by Bob Mullen back in the day) but definitely the old #2385 TRW pistons down in the hole. Probably should have changed them when I did cam and all new bearings, but cylinders were still in good shape.

I have a cc'd compression ration of 9:1 due to pistons down in the hole. (The TQ sits on opened up LD340, 1-7/8 headers.)
Mixture screws in the 1-1/2 to 2 turns out.
Float height is set at the recommended 1" setting
Fuel pressure has been at 6.5# (may lower it a bit)
Static cold cranking compression 160#
Cam ground on 110* and is 235/243 at .050, lift is .526/.546 (smallest Lunati Voodoo solid lifter)

So, how does that fit for future story-telling information? (Love to read your posts!) :)
