Hey folks, looking for some help/opinion on swaping my 360-3 for Pro Dominator.

My current combo is as follows;

468 ci
360-3 w/ 1050 dominator
360-1 245 rp
12.4-1
Solid Roller
724/693
277/284 @ .050
110 lsa installed at 106
1 7/8 tti

904 / 5200 stall
3.91 Gear
3200 lb a-body


I would like to run the pro dominator on this combo.
I have talked to a few very knowledgable people on this, and as expected the opinions vary.

First question is, will I see gains going to the w2 pro dominator on this combo ( I realize we will have to change to rec port)

Second question, what size carbs should I use.

Looking forward to the responses on this.

Les.
