well learned something new today, although I guess I should have know this. Got some head gaskets from Flatout with the combustion chamber and valve pocket area undersize so I could fit them to my block(flathead ford V8). I matched one up to a spare block, same bore, and then to my valve relief area on the heads I am going to run. Well, put the gasket on the motor in the car and the bores are off by .050 or more. Seems the bore spacing is just not the same. Passenger side is worse than the driver's side. I guess I would have to make the gaskets, block and heads a matched set from the start.

went to chassis dyno today and we are pleased that our motor is improving. May not sound like much to you guys but it made 223 rear wheels, still climbing at 4700 rpm. that's supercharged flathead on gas. Picture is plugs after one run, what do you guys think?

Looks a bit lean to me. What brand and heat range is the spark plug? Did you pull the plug after a clean shut off on the engine just after the pull?

Hi Ron,
NGK B7HS, backed the car on the chassis dyno, changed plugs, made one pull, drove off dyno onto trailer. EGT peaked at 1200

Considering you drove off the dyno and onto the trailer I would think the plug would have gotten a bit darker. EGT temps are not bad but best reading would be air fuel during the pull. Still looks lean but when your running at the higher elevation at Speed Week the color will certainly get a bit darker. Are your plugs 3/4 inch long?

afr during pull was 11.7. Spark plugs are 1/2 reach. We tried extended reach iridium and some hit the valves.

The air fuel ratio is very safe I think your in good shape.   cheers
