450 cfm carb.

[Fordestes]

anyone on here using a 450 cfm holley carb on a 3-5/16 x 4.00 v-8 with a 1007 b cam, what jets and p.v work to satisfaction? I have had this carb on the shelf for about 10 years or so, it was a factory application for a 1974 ford something or the other, the only reason I hung on to it is to use it on a flathead, also it has been soaked in cleaner but it still has some sort of electrolisis or something on the outside I assume from setting for so long , would a soaking in vinegar remove the texture it feels like a dusty coating but it is discolored kinda dull finish, I dont like to bead blast a carb because I don't think the blast media will all come out and I don't want to get silica or glass beads in my engine, I hate to waste an otherwise nice carb, the inside looks great. also I want to convert it to a manual choke, any one here have the man. choke parts they want to sell?
Thanks,
Fordestes,
