440 Engine Rebuild advice

And this is how **** hits the fan.
Nope... I would not use that cam unless I was sacrificing the power goal for streetability.
But heres the issue..
You have someone already enlisted to help you... and you go get second opinions ..which will more than likely bring to the attention of the builder helping you....and **** hits fan. Dont take this personal
... cause I don't mean any insult...but I'd tell you to kick rocks and don't ever approach me for anything ever again if you did this after enlisting me to build it.
He either knows how to do it or he doesn't.. but you cannot have more than one cook in this kitchen. It either gets morphed/interwoven into the current plan..throwing it off and ruining its overall power curve and manners.... or itll be arguing and you'll always think he left power on the table.
I had someone do this. The machine shop cyl head guy at total performce.. 'hacks' tried taking my customer... I put all his **** in the back of his truck and put it on the street and said pick it up...more like tow it.

He called back 9 months later apologizing and saying it not only cost him 2.5 times as much than I was doing it for.. but that it had no bottom end torque and he "wasn't happy with it".
If you doubt... I'm out. Confidence is key to a good relationship with a builder.

And if his machinist falls into the "doesnt know " catagory ?
