ok so i want to get a good carburator for my suburban. i was wondering which ones yall thought were the best. ive seen alot about how the holley truck avengers actually do flood alot. is this true? and i need to know where to order one and if my 88 3/4 ton sub is a r20, v20, c20? i think its a v20 but any help would be nice. Also, i saw some really sweet diamond plate mufflers but i forgot what brand they were. and if anyone would suggest a certain type of muffler.
