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.
I would consider changing the cam at the same time. You can use less duration to get the same peak RPM. If you don't get a cam for a TR, you will see a soft middle RPM, and a very narrow power curve. A tunnel ram can and will make more power everywhere if the cam timing is correct. I think tunnel ram intakes can run a narrower LSA to keep them from making power past peak any further than you need to. I'd do it in a heartbeat. Also, thumperdart or jmark should go through the carbs.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

Once you open the ports at the flange to match the heads, you'll need to correct the taper in the TR ports all the way into the plenum. Once you do that, it should work really well.
I would use 2 950's or 2 1000 carbs but you could try 2 edelbrock 800 carbs....believe it or not they work very good in TR applications.
The cam looks good to me, but what do I know...

I'm a big fan of tunnel rams, although not that involved with small blocks. I really liked the old 660 center squirters when I ran a 440 cube 440 block and Weiand TR. My new build is a 500 cube 440 with a TRE sheet metal manifold and 2 850's with the choke horns milled off. If you get the 660's look for the version with both front and rear metering blocks. The later ones had a metering plate style (4160).

Leave the cam as is.. open up the intake and you might change the rear gear EDIT A pair of 1000 cfm or 1050s

Thanks for the replies fella's, I appreciate it.
Bore: 4.185
Stroke: 4.250  What block? Is that a 2.0 Rod crank? Pump gas at 12.4 CR? Any projection on HP? Yours sounds nice.  I am working on a similar slightly smaller motor, but 7000 is too risky for my application
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

Will get it to the track this summer and figure out where it's at.

Gotcha...........I prefer what works over "looks" any day......... Yeah, I hear what you are saying. That's the reason I'm asking for opinions. If it's gonna make me go backwards, no point. If it's gonna work better and look cool, I'm good with that!

My high 9 second 73 Dart was a good tenth and a half quicker with the TR than a single Dominator. I loved it, seemed more streetable and the 60 foot was the same or better than the Dominator.

I have a W2 416 with the Indy-3 intake. It is fuel injected with a 1000CFM throttle body on it. It is actually pulling some vacuum on the throttle body at wide open. I bought a nice W2 Pro Dominator from a moparts member to have converted to EFI so I can add another 1000CFM throttle body.
