340 dyno chart thoughts

There's literally no chance in hell a 241/241 with 106 LSA is going to have the same vacuum at idle as a 231/231 with a 110 LSA.. He'd be looking at a loss of 3" vacuum at idle MINIMUM. You need to stop.

I would agree with the above statement. Looking at the data I see an undercarbed, overcammed, low compression engine IMHO. Would love to see what a compression test reading would be.

If the OP is happy though just run it as is--it will be just fine I'm sure. J.Rob
