52 Suburban - With a stock 261, two barell carb, headers, 3 spedd muncie trans and stock differential, how fast or what can i expect for reasonable crusing speeds? I got the truck on the highway this weekend and from the rev sounds and the 'whining' from with the trans or diferential, 45 was teh most i was willing to do - do these trucks just sound like that or is that all she has? thanks
