The Indy 400-3 is a MW port intake. The Mopar M1 4500 is a standard port intake. The Trick Flow and Victor intakes are std port and 4150. I dyno tested the 400-3 and a Mopar M1 4500 on my 470 dyno mule. Both intakes were competition ported by Wilson. The Indy made more peak power which wasn't a surprise but we're starting to get a long way from where this thread started.
