I will have to agree with Jack and Greg the A/F needs some tuning.
Way to lean from 3500 to 4500 and a little between 6800 up.
It must be really lean below 3500 RPMs.
Next time you get on a dyno start the runs at 2000 to 2500 RPM. That way you get to see the carbs do all its transions.
You don't to see it above 14 any were on the graph
13.5 is best to keep it alive for a long time. You gona lose about 5 HP but its better than 5000 bucks!
That is the set up on the engine. Like CR, Cams, what size carbs. What size ventures, jets, ACs and emulision tubes do you have installed?
We have a 248 in ground Dynojet. It was probely the best tool that I ever bought. Go find one close and tune on it.
You have a good start it's just gona need a little more dyno tuning.
Great job Man!
