Pat like you said I have nothing to compair it to. I have decided to ship the 112 LSA cam back and get the 110. Hopefully I will not have to wait forever to get the correct one. My LS6 454 is scheduled to be worked on Jan 1 to switch cams, make sure everything is perfect, and then break in this new engine plus run it on his dyno. I will be interested to see how it fares! Have a Merry Christmas Pat and if I lived closer I would have you do one of those oval exhausts for my 30 Brookville roadster. You sure do quality work & are free to share the wealth of knowledge you have about BBC.
