I have a 383 that I recently built and had a couple of questions regarding the intake and carb that I think some of you will be able to help me with.

Car:
67 Belvedere II
833 4 speed
3.91 Suregrip

Engine:
.030 over 383
12.4 : 1 compression
Comp Cams solid flat tappet , 247 / 255 @ .050, .600 / .624 lift, 109 LSA, 103.5 ICL
Trick Flow 240 heads
Trick Flow intake

My two questions are:

1) The ports on the Trick Flow intake are noticeably smaller than the ports in the heads. Would there be any gains to be had from some intake work done, perhaps such as a deep port match like Hughes offers? Trick Flow must have sized the ports like they did for a reason, but not knowing why, I had to ask.

2) What size carb would you guys recommend ?

This is a mainly street car, but I would still like it to perform as well as possible. Let me know if there is any other info I can provide. Thank you for any and all help, it is greatly appreciated.
