Lets face it... most guys can assemble a engine to specs but we dont run as many combos to get the big HP numbers... the builders have run numerous combos to find the hp.... I'm sure in the begining they didnt make the numbers but with time and combos it came around...thats way we go to the pros... I took the word of a cam guy and it ended up wrong but that was part my fault but I'm thinking about changing it..... this is JMO
