Most use a drop base air cleaner for clearance

The 280H cam is a pretty stout cam. Might want to idle higher than the stock converter will be happy with. Only one way to find out. Run it and see. Some manifolds are higher than others and could present a clearance problem. When I had my car carbed, I was able to find a lower profile Weiand maniflold.

i dont think the stock conveter will like it.. i had a similar yet roller cam in a carbed camaro with a stock stall and you could feel it pull on the lope. not saying it won't work but for traffic its not going to be ideal

I would but i have 1/8" clearance above the carb so can't even put a air cleaner on for now but a good idea may have to go with a special hood
