Dyno run parts

We own our own dyno. The engine combinations that work are the result of years of trying combinations that don't work. I read a lot of stuff on the internet and know it's BS because we have done our own tests, like Dad did.

My father used to build NASCAR engines as an independent west coast engine builder. About ten years ago I meet a camshaft grinder that said, "You're Bill LaRoy's boy? How did those camshafts work? "Your dad would come into the shop and say, 'Build me a cam with this LSA, this duration and this lift.' "He would come back a week later and say, 'Now make one like this.' "And he would never tell me how the last one ran!"

I still have his cams on the shelf from the 60's, 70's and 80's. A few years ago a cam grinder from the East Coast even wanted to buy some of Dad's cams back.

We start out testing an engine for a truck and my son will say, "Hey, what about we try this?" It may be a part from Dad's stash or something new we have the money to try and maybe use later in something more appropriate.

It's not the whole answer to your question, but it is how it happens around here.
