SB vs BB who wins?
I think John said it best. The one with the best combination usually wins. I have been around drag racing for a long time.
I have seen big and small blocks run really well and I have seen big and small blocks run badly. People forget that it takes more than an engine to make a car run well.
Transmission torque converters for instance can make or break a combo. Then there is suspension if it poorly designed it can really kill your combination.
I would take a well thought out combination any day over a big horse powered motor. Big horsepower takes a lot more planning in my opinion the combination has to be done correctly if not what is the point of making all that horsepower.
