you need about 305-325 cfm depending on VE to make peak power at around 6500 rpm on a 427. The comp 227 afr has that covered. to make peak power at 7000 rpm your going to need about 330-350cfm

There are very few intake choices native to LTXs. Most just convert single planes like Vic Jrs or Super Vics.

last thing I heard was Dart didn't like the way the tests came out and are retooling to get a better block before it hits the public, and it will be another couple of months now...
