Yea your right about the dynos and flow benches and the other guy says its laughable when a Pontiac head is on the flow bench yada yada yada but the last I checked we don't race dynos and flow benches, at least I wasn't driving a flow bench when I beat a camaro in my Dakota. Ehhhhhh, scratching head.
But we race on the drag strip for instance and when you set records you can argue all you want but the record still stands.

I know its hard to accept but the sbchevy is no longer cream of the crop and it never has been. Fact is there is always going to be someone faster and they are in some cases do it with parts that are laughable. Yea a rod does not make more power etc but why do so many sbchevy fanatics in here ask for longer rods, why do they sell them. Must be some kind of sbchevy logic that I do not understand. Maybe they don't like their skirts collapsing, thrust faces wearing, pistons separating, I don't know. Like I said, must be some sbchevy logic and sbchevy money floating around here that I just don't understand or make.
Here is a quote of sbchevy logic here:
"?Really, the mainstay engine in circle track racing today is still the 18-degree small-block, which is a subtle variation of the original 23-degree engine,? Sperry explains. ?It?s a roll of the casting to stand the valves up and get the ports up in the air a little higher. The SB2 is a bigger departure from that, it does have some compound valve angles in it on the intake side and it does have a little more reach as far as rocker-arm geometry, but it is still fundamentally a small-block Chevy. Maybe you?re taking some of the big-block thinking and marrying it into the small-block design, but it?s still the same engine.?" (Ron Lemasters, Jr., The History of... The Little Engine That Could The Chevrolet Small-Block Is Still The Engine Of Choice In American Circle-Track Motorsports,

I think I will squeeze a nut over that!
Pontiacs are inferior to the sbchevy, especially that 3 inch main that slows them way down. Must be that .350 diameter difference that sets these engines apart. Valve angles don't matter and only hinder performance when they are brought closer and closer to vertical on other engines besides the sbchevy, thats why the sb2.2 head has them so close to vertical, a head that resembles no sbc ever used in a gen 1 engine but had to have it to remain competitive. Hmmmmm :mwink: must be more of that sbchevy logic. Funny how the 23 degree heads for NASCAR racing has Pontiac cast on them, must be more of that sbchevy logic.
