BBC VS. SBC...... Whats the call?

[CrashPro993]

I recently purchased a 71 GMC LWB, My first major purchase for this thing is going to be and engine. I know there is plenty of options out there. I want to stick with carburated, mainly because i don't want to deal with all the wiring and I want to keep the cost somewhat down.

I'm looking at either doing a SBC 350 or 427 but I'm not sure on the durability of the SBC 427.

Or I'm looking at doing a BBC 396 or 454, just not sure on the power to weight ratio. And the fact that my truck is going to be almost on the ground when I'm done with it.

What's your guys thoughts on a BBC VS. a SBC?

Thanks for your help
