Interested in going supercharged...SBC or BBC ???

[DRJDVM's '69]

I'm already thinking about going a different route with the motor in my car. I'm really interested in going supercharged or turbo (probably not turbo becasue of cost but maybe)...

The motor I have right now really wouldnt be up to running much boost without changing alot of stuff, so I figure I would be best starting from scratch. That way I can really maximaize the potential of supercharging rather than just slap one on but be limited to pretty low boost levels....that seems like a waste to me.

So if I'm going to start from scratch, I'm debating SBC vs going BBC. I have alot of nice accessory stuff for the SB ( headers, oil pan, dampner, etc etc) and the mounts, clutch linkage, front springs etc are all for SB and pretty new, so I would have to change all that too.

Alot of guys seem to be building small blocks for supercharging rather than big blocks.... Scott G for example....... why is that ???? Is it based mostly on cost ???? I know BB are usually more expensive to build but not that much. I guess I'm debating whether all the of the extra stuff to convert form SB to BB is going to end up costing me alot more in addition to the difference in cost of the motor etc.
