Bang for the Buck Thread

The bore and stroke of the engine matter little in where the power is made since it is the cam that ultimately dictates where the power is going to be. The better the head the higher rpm and more powerful the engine will be.

displacement has a huge effect where power is made, I say heads and displacement has more effect where the powerband will be obviously cam has a role but heads and displacement set the boundaries. Eg.. A comp xe285hl gonna be very different in vastly different combos of heads and displacement from a 273-572, there not all gonna operate in the same powerband.

If stroking with a 4 inch are is a limitation to rpm, then please explain why a NHRA 500 cid engine will spin 10K.

It can displace enough air to do so.

Generally speaking, in hot rods and many race car engines, the longer stroke for a bigger engine will have the power leak earlier in the power curve. This is seen with an otherwise apple to apple comparison. An example would be 340 vs a 408. But to use this example as a rule of thumb and to rpm limitations is not wise or in stone.
