I'm in the process of rebuilding the 350 in my C1500. Its a daily driver and I was looking at CFM Tech's throttle bodies. Does anybody know what the stock specs (ie, bore size for the air intake holes) on the TBI for that model? Any and all help will be greatly appreciated. I want to keep it a daily driver and don't want to burn more gas than needed.

the stock intake holes are 1" & 11/16. so in other words, 5/16" short of 2 inches.
