Tunnel rams are intended to shorten the intake runner length so the engine has a higher rpm power band. The problem is that the tunnel increase the area as well as the length. The area is so big, it effectively eliminates the distance from the point the intake runners enter the plenum to the carb. The organ pipe pressure waves operate only in the relatively short intake runners. Great for high speed tuning and performance but deadly to low speed performance.

HUH?
Proper tunnel rams increase the power across the board.

You have been dealing with waaaay overcammed engines= bad combinations. cam not matched to induction system.

4 days ago we just put a brand new set up with 500s (bought as a set) on a 360 Mopar.
