The point I'm making is most big blocks of that era 73-75 suffered more power loss then the equvalent small block. a 340 was rated 275 hp a 440 same year was 375 |In 1973 they were 340 net 240 and 280 net 440. That is big diff.

Yes, but you conveniently omit the fact that in 73 the 440 had almost 100 more ft-lbs of torq and at a lower rpm. In two identical 73 RR's with the same converter, trans and gears, the 440 car will win. The extra torq at a lower rpm will perform better with the stock torq converter and give the oomph you need to get that heavy car moving.

If you're comparing a hi-cr era lightweight 340 a-body to a smogger low comp 73 440 b-body you are NOT comparing apples to apples.

To the OP, a turbo or supercharger setup would make your 340 feel like a totally different animal. If you want to do something fun on a budget, you can pickup a used centrifugal supercharger like a paxton sn2000, sn93 or sn89. They are perfectly sized for a small block and don't go for that much $$. Pop in that 268 cam, do a set of headers, intake, carb and that supercharger and you could be in the 350-400hp zone easy while giving you the bottom end torq you need.
