LT-1 Replacement Carb Suggestion

[GaryH]

It was a Holley kit for the 3310. I purchased two 8.5 power valves and the blue bowl gaskets separately. I matched all the holes in the new gaskets with the old ones and they all appeared to be correct. I did not replace the floats. They are brass and appear original. I'm lucky if there is more than a thread or two sticking above the bowl on the needle & seat. You have me thinking I should pop this back apart and double check things on the floats and try some different needle and seats....
