5.3 vs. 6.0
This is all hypothetical of course..
Both engines are using stock short blocks, aftermarket cam, heads have just clean up work done, Edelbrock carb intake, appropriate sized carb. Both have properly setup valvetrains.
5.3 makes peak power at 7500rpm
6.0 makes peak power at 6500rpm
How close would they run together? I know the displacement hurts the 5.3 but the added RPM will help a bit.
At what point do stock castings fall on their face and prohibit more power?
