Thanks guys.. I have been fighting with my car for a while on timing and fuel issues.. I have a code 41 now that means lean mixture at all times with no change. I have a 155lph fuel pump, AFR set at 40lbs with line off and still lean as can be.. my plugs look like i never fired the car up. I also have a code 67 engine tempurate out of range.. I have the 160 degree thermostate in
my car. could that be causing my lean condition?

What mods have you done to your car?

First I would throw out that 160* stat. It's not allowing the car to get up to the proper operating temp! I have a 1958 stat and it has worked the best out of any other temp stat I have used.

When you got the code 67, how did you go about doing that? KOEO, KOER? Was the engine cold, or warmed up?

When I bought my adjustable FPR, the instructions said that the stock regulator is set at 43psi, but I had always thought it was 40psi. At any rate I would try upping the fuel pressure out of the regulator some more. I have mine set at 46psi at the moment and it definitely helped keep my top end from falling off.

Oh and I have my timing set at 15*.
