74mm TB and MAF upgrade

If I were to change the 68mm TB and MF with a "plug and play" upgrade from my local MB guy what kind of HP increase can I expect? Is it worth the time and money?

Do you have an NA? If you do a search on 74mm throttle body you should get lots of info... not sure if it will answer your question though......

The SRT6 has a 74mm TB stock......

No one has the definitive answer for that question about the HP increase yet. Let's just say 'some'.

This is my modification, a variation of the common mod. My mod uses MB parts exclusively except for the home made spacers.

On this, or really any other N/A mod.

Dyno numbers and 1/4 mile times are scarce as hen's teeth, when it comes to the nuts and bolts of "Horsepower per mod?" While they may exist, I've never seen them documented like the numbers of the SRT have.

Lots of assumptions out there though.
