I was thinking the same as the poster who stated if you want better flow buy headers. I don't know too much about BB, but I don't see where there would be all that much difference if you are not putting together a race motor or high output motor. I would be very very VERY cautious about cutting into the frame. That is the base of the truck, and if you are using a big block with any kind of torque you run the risk of twisting up that frame, then you are in a whole lot of trouble. Just my opinion, and I am a weekend warrior at best, so take it for what it is worth. RR
