Dave sorry to have seemed to p you off-----

OK tho, do you want to discuss these items for a street car or a race car????to me a race car is where you want to as fast and quick as you can, not a dial in or index----

And a higher performance street car that you occasionally take to the track to see how quick/fast it is must still have street handling manners----

I am ready to respond to any item you want to discuss/compare and I believe that my experience with racing, street cars and machining/building engines won't take a back seat to anyone

I am now going to read the gm perfornance link you posted and see if there is any thing relavant to this topic
