Trick Flow 440 heads, The Real Deal?

Depends on what you're doing with the engine. If it is a drag race car and you want the most power out of it then i'd go with the M1 4500 intake and a Dominator carb. Any sort of street driving or street/strip type of use I'd gladly give up the few hp and run the TF intake with a 4150 carb.

Good question on the ported intake. Mopar Performance just made this intake too small for an engine like mine. They must have designed it for a stock 400 engine. Some of the aftermarket intakes are made bigger. For example, Indy did a 440-3X intake which is designed for 572 engines. But yeah, most of the time the intakes are made way smaller than they need to be for higher power combos.
