I think it would depend on what modifications had been done to either car. B20 vs B18, engine work, carb set-ups all make a noticeable, but not amazing difference to the behaviour.
I suppose the '72 model would have dual-diagonal system brakes, would it, like the later 140s? B20 gives you better grunt in the low/mid range but no real gains at top end. Gear-box is stronger in the later models and also check where the body parts were assembled. No dissing the UK but I fear the Olofstrom cars would probably hold together longer.
