Tunnel ram Tuesday!!!...

So, at what HP level do you need to switch to MW ports? Mine is a street car and have always heard it would kill all the bottom end. But then they also said I can't run a tunnel ram, 660s and a spool. Works perfectly to be honest. Changed the spool for a SG but not because it needed it, just swapped center chunks for better ratio.

I could run max wedge ports now.
It will raise peak torque and make more HP.
The ports I have now are from a Hughes valley pan, on my heads I blended that size in just before the short turn. It was about a .450 CSA gain and over .550 on the tunnel ram.
One thing us Mopar guys need to understand is our standard port big block heads are just about the same size as a camel hump sbc, so were way undersized.
Big block Chevy, 460 Ford, boss, Cleveland, modern LS6-7 heads all have big ports and run fine. The small cube engines just need the rpm to make them work well.
Chrysler max wedge port is just about the same as the head that comes in Chevy trucks now in 6.0 liters.
If I remember correctly I'm making 600 ft lbs at 3000 rpm, that's pretty street friendly in my book
