Sbc's on cost less if your doing stock rebuilds.

Pick up a summit catalog and look how much the good stuff costs like pistons, rods, cranks, heads.

Pistons will be withing $50 or so
Rods vary as their a more choices for the sbc
Cranks will cost more because I've been told that sbc need a forged crank to live (told by the experience of racers at several tracks) Of corse the pontiac crank should be free sbc $300 up
The added cost of the crank made the descision for me to continue running pontiacs.

There are alot of options in heads for the s.b.c it depends on your goals. Of course the same can be said for pontiacs too. The 455 can make the same or more power as a sbc at 1000-2000 rpm less with less "exotic" parts.Besides the 455 fills the engine compartment better
