I agree on both statements. Camshaft LSA is sometimes not about the most power obtainable. If it doesn’t idle the way a customer likes, it’s the wrong cam. Even if it is a proven power maker. The customer must like what he hears as well as how the car performs.
I’ve done some jobs where the car own hates that chop chop chop sound. Others just want that smooth idle and high vacuum for there power brakes and easy pedal driving response. There not after max power, just a feel good drive.
When the 128 formula came out, the only thing I put down in print was it’s a formula that doesn’t cover everything and can’t. It’s because of individual taste and likes. Nothing about it being correct, the best, etc….
Nothing more, nothing less.
