318 4 bbl and intake upgrade

I'll never understand why people insist on spreading total misinformation. Chrysler didn't give a **** and shinola about the "port mismatch" and it didn't make a hill of beans difference. But people are gonna choke, puke and regurgitate the same old WRONG bullshit over and over. It's just that. WRONG.
Port mismatch matters. Port mismatch doesn't matter. Both are blanket statements that have exceptions. Not saying in this case it will matter but in some cases it does.
Chrysler did a lot of things based on the constraints at that time. Such as cost, availability, time, emissions, politics and performance to name a few. That caused a lot of compromises to be made. I don't think that just because Chrysler did it that way means it couldn't be done differently or even better. The OP has lots of options.
