Exhaust limits/Carb choice

The added CFM of the T-Q may be helpful, but not needed. 650 cfm is enuff to really move a powerful 318. A T-Q though larger has adjustable air door opening size and it's adjustable on when it opens making this carb fine for the 318 as well though it's 100 cfm (or so) larger, it will not be to much.

The bottom line is what ever carb you feel comfortable with is the one for you.

He recently picked up a '67 Dart with a blown 318, but the body is fairly straight and the car has an 8-3/4 Posi with 3.55 gear set and a 904 AT. I've donated a spare 360 to the project which was intended for my '37 Dodge PU. The motor is bored +.030 and is filled with KB107s yielding 9.4:1. The cam is a Crane H278-2 (222/234, .467/.494). The manifold is a Wieand Stealth which is a dual plane similar to an Edelbrock Performer RPM, but with a spread-bore flange.

Depending on the use for the car. Toy/Street/Strip/Daily, that would vary my decision. The TQ will be a much more humble daily driver. The Holley will get it done better at the track, but be more finicky.
