My next one I am going to block the bypass hose completely. I fail to see how bypassing that amt of coolant is for a good purpose even though it must be or it wouldn't be engineered that way but I am going to see for myself(in a street car). We blocked it on our (circle track) stock car & no problems. would anybody care to comment?

The hole they`re talking about is just for preventing airlocks under the stat while filling the system.
I used a 1/8" hole on my 2.5 shadow and it would not warm up on really cold days. Since all that needs to go thru the hole is air 1/16" should be plenty.
