#1 Just bought a 72 GMC K2500, what gears would be in it, 4.57 or 4.10???
#2 I was looking up info about 2 of my 350's; one is a TBC (1970) and the power ratings come up as 255hp as expected. The second is TRK (1972) and it comes up as 175hp? Are my sources wrong or was there a power drop?
#3 I’m picking up another 350 (part of the K2500 deal) its block casting 3970010. I’ve been told its high nickel (it's got the 010) and 4 bolt mains. Thing is it’s a 2 barrel? Was this custom ordered or standard in 69 or something?
