Carb Swap?

I have the same cam in my 360 with 11.25. Your kind of mismatched low compression with a bigger cam and a race type intake. I have that intake on mine and lost some performance over the torqued II I had on there. If you really want a single I have my torquer intake for sale it has the a/c provision I think. Otherwise for a heavy truck like that I would go duel plane and keep a smallish carb around 650 dp or vacuum
