Came up on a deal the other day, im not real real motor savy as far as high perf. goes. A buddy has a npi block in his older sn95, wants to trade blocks. I get the npi block, keep my pi heads, get 270 cams. edelbrock intake manifold. intake plenum throttle body lt's, or/h and a catback. Obviously my compression would go up quite a bit. But is this swap a good idea? theres something about going back in time that doesnt settle quite right with me. I already have shorties catted x and weld ins. What do you guys think.
