9002S Thermoquad carb
Hey Rob; good catch on the TQ to AG, being basically a no-go.
-Id like to add that some would argue that a 625 is too small for that cam, but I would argue that a .509cam is a bit big for street. The two are seldom together. I think, just my 2cents, that they can,on the street, be made to play nice together, for like, 80% or better of the time. I mean just how often is that streeter at full load/full song? (Having said that, I wouldnt give up my double pumper;theres something, just ,right about 4 barrels open right now,anytime.) And a small-primary carb can sometimes give back a little torque that the big cam gives up.And if money is tight, its kind of a no-brainer; Tune it and use it.
-I ran a 600 vacuum secondary on my H.O.360-4spd S-clone for one summer.It wasnt thaaat bad.By the end of the summer I had almost forgotten how it ran with the bigger carb.Not saying Id ever go back,tho. But a spread-bore is,IMHO, the best of both worlds, for a streeter, on carbs. Its just too bad the Airgap doesnt come in a spread-bore configuration.Some day Id like to try one of those Offy Dualports. Too bad they only come in small-ports.YadaYadaYada. Time goes marching on.
