Street 572 Hemi, tunnel ram and dual 1150's? - 03/08/12 03:07 AM

I've collected most of the parts for my new street engine. It will be a 572 Hemi with ported Stage V heads, 2-1/4" headers 4500 stall convertor etc. I have always liked the Weiand tunnel ram and want to run one with dual 1150 Dominators.
Does this sound like a good combo? I know the engine is substantially bigger than the 426" the tunnel ram was designed for but I'm hoping it will work out if I shift it around 6000 or so?
Camshaft will be the last thing chosen but it will be a solid roller for sure.
What sort of Dominators should I be buying for this setup?

Thanks
Sheldon

i run a small weiand tunnel ram welded to fit my max wedge ported heads on my 493. it makes for a very good street combo. but a bigger intake is always on my mind and with you haveing 80 more cubes and big heads, it will be on yours also

Keep an eye on posts from my father (quickd100) he will be running a weiand tunnel ram on his 605 Hemi in the next month or two.

When I stepped up from 2 holley 750's,I went with the Pro Systems SV1 so I'm partial to Pro Systems.The new holley ultra looks real nice and Quick fuel makes a quality carb.
Will it be street & strip??

I think you'll be must happier with a set of 750's instead. The motor just can't use that much cfm. Dave

99% of the guys cant get one Dominator to run right on the street, your wanting to run two..
Just have two custom carbs fixed in a 4150 flange. It will run well... I ran two 660 center squirters on a 572 Hemi with cnc ported heads, solid roller and lots oif compression... Throttle responce was fanominal, and it run clean too...
These carbs were too small, but the car still ran in the 9's with those..

I wanted to do the same thing at one time w/ my hemi. All the hemi gurus told me the Weiand t-rams are too small for a big cube engine and that I was better off w/ what I had...big single plane and 1200 dominator.
You ought to look for an Indy t-ram and get the plenum spacer to gain some more plenum volume...b/c even it's on the small side. Or you could always get a 2nd mortgage and have someone build you a custom sheetmetal manifold.
Of course this is if you're after max power like I am. I'm not willing to sacrifice power just to have the look of dual quads.

I would imagine a pair of 4150s would be much better on the street, but a pair of dominators look so bada$$.

I have used the early Holley 9375 non HP on a 526 C.I. wedge motor with Indy 440-1 CNC ported heads with both te Indy 440-3 single four intake and then switch to the Indy dual 4500 top tunnel arm with the same two carbs I had tested on that motor earlier that day. The motor pick up 30 HP and 20 some Ft. lbs more torque, (not exactly sure now on the torque numbers).This is a bracket race motor that I have sold to another racer that wanted the single four intake and carb., not driven on the street yet

If it's the look two 750 dommies would be the ticket they come with power valves and would be more street freindly

Thanks guys: I think you guys saved me a bunch of cash. Hemi Itis, I like that setup, mine will see a bit of strip but it has to be streetable.

When I bought my Holley 1050 3-curcuit Dominator, it came with power valves in the primary and secondary. And 88 jets.

I put over 2500 a year on my junk and hope to get to the track 4 or 5 times a year.In these parts in fair weather there's a cruze in every night 'cept Sun & Mon.I knew I needed a large pair of carbs to turn the wick,so when I did my research those are what I ended up with.Took me a while to save up and pull the trigger.There are formulas to calculate how many CFM is required for any given combo.I chose the new design as a stepping stone towards EFI.

You mentioned that before, and I always think back to that. 1-1050 on the street was a lot better than 2-1050's and....ITS FASTER at the track!

I have an efi bug catcher set-up on an indy tunnel ram, and drivability is awesome...My problem is, the Nostalgia guys aren't going to make an exception to let me run it, so I have a choice to make...

-Single plane intake & either a Dominator or an SV1
-Make a tented top plate for my existing tunnel ram and put a Dominator or an SV1 on it.
-Switch my bug catcher over to mechanical injection and forget about streeting it...

I have quotes for all options, but haven't decided. You guys with the SV1's, please keep us posted. My engine is a shade over +700 and I like some of the benefits I see with those...

Jim...Don't you have a tight converter for the nitrous though? I bet the t-ram would be faster if the combo was set up for N/A...looser converter.
