hi, i have a 87 350 with a throtlebody on it i was wondering if anyone makes a intake to put a carb on this engine.

i Was also wondering if you guys think it cheaperor or more expensive to buy a crate enginge, rather than building one for about the same type of power as the one in the link. This link has a engine that looks like a pritty good deal to me.

Prestige High Performance Engines - Chevy, Chevy Long Block, Parts

(hope i put the link in rite i've never done that before)
