i don’t think its a blown power valve, i think my idle mixture was set alittle rich and my floats are a little off but not so much so that its over flowing with fuel. i think the previous owner set it like this because i live in Wyoming and cold morning start can be tough to say the least when its 25-30 bellow freezing. the truck runs great and has good power i think i just need to get used to big block fuel milage or lack there of. i know this is probably the wrong thing to say on this sight, but I’m actually swapping a some what hopped up 12 valve Cummins turbo diesel and gear splitter into the truck in the future. and im going to build the 460 alittle and put it into my 32 Model A that tips the scales at 1800 lbs with me in it. im hoping to have an honest 11 second street car that was built on a milk money budget
