I had to go to Indy's site to see there is a Mod Man for smallblocks.

I haven't seen effusive praise for the Mod Man for the other engine families. Frankly it's far easier to find anger because the intake doesn't work well. Based on what I have found I would shy away from it. For one thing it has huge internal volume. So, feeding a 650hp monster motor it may work just fine. But for anything remotely resembling street use IMHO forget it.

On the other hand an old tunnel ram can work quite well. Look for an old fashioned one that doesn't have sewer pipe sized runners. 9 out of 10 people will tell you it won't work, but they are mistaken. Because of the ram effect it should improve torque all over the rpm range.
