Ford Motor 292 V8 - Loss Power

By accelerating Pirde Power. I changed rings and the second day of filming began the problem. Revice the carburetor pique pump and it works well. I made platinum tune, etc. Revice the benzine pump, all good, regulation of valves, does not suck air. It goes well but when it continues to accelerate, it empies to suck, and then it is long but when climbing another one the power is declined again as if they assumed and released it, I do not know what else to review.

Hello chick.
How is the air filter? Check the exhaust tube and the multiple, which are not clogged with coal, for example, check the valve calibration. Luck.

Thanks Servilimit. The engine is cleaned complete including multiples, and valve calibration. La Revice.chisk
