Not sure what your issue is with people asking questions is. You make a post stating something most people have info to back up their post and can answer questions regarding their posts.

Pontiacs are long stroke engines compared to say a BBC of the same cid. They pull harder through the carb. At least Dale explained it to me when I asked him about it.
Called him up getting info on the one I have. Its a 1400cfm and asked if it was crazy to try it on a dyno test with my 461. Was told it may or may not work well but shurly would run like crap at part throttle.
The engine I am doing now, I am told wants a good 1150 carb. Not sure if I want to spring for it bracket racing but might. I have a 1050 3 circuit I turned into a 2 circuit. The fellas at Performance Carb and Speed tell me its the one to run. A 1150 might show a few HP more on the dyno but the car will pull better, ET better with 1050. They tell me they can get more fuel through the mid range fo me. Knew about it when I asked.
I have heard stuff about higher end Pontiac NA guys leaning out and burning pistons until they got the carb right. More fuel in the mid range. At least that is they way I understand it.
