ok, I was too tired to explain myself and just gave you some bullet points, so now i'm even more ticked off, so they're going to be even more brief. Someone with more time can fill in the blanks.

-thumper is bad with a TPI setup. it won't work, or it'll work really bad
-use a carb, and a big cam
-or use a smaller cam and go fast with your tpi, 114LSA, computer compatible style
-retrofit isn't used in a factory roller block like yours
-what are you building? ie, what are you replacing? just cam? everything? if everything, the block is pretty cheap, might as well pick up a bigger one.
-whoever is helping you pick parts, and suggested that thumper doesn't know what he's doing.
