Comp 34-602-9 if you like a nasty idle or 34-443-9 the first will make mor power. Do a simple bowl and gain a bunch of power.

In my opinion, I would not use a 429 block because of the shorter cylinders. I would use a later 460 block.

What is this intended purpose? is this a cruiser, a drag racer, a 4x4 truck?
What fuel to use? pump gas, or race gas?
