Holman Moody intake & 750 Dominator

Post #1 by 82F100 » Sat Jun 06, 2009 1:26 pm

Has anyone used this combo before? I know triple webers or 3 deuces is the best choice for the big six, But sometimes ya just gotta think outside the box :hmmm:

Wow! That pup is going to have to flow and pump a lot of air to utilize a 750 I would think.

Hey Rich,

Put a flat adapter plate on top of the intake, then add a roots blower and the 750 dominator. The intake has the bracket cast in the under side of the manifold to add a brace down to the block for added support of the extra weight. It would definitely flow enough then!!!

Scott, I would have to do the same but because my engine sits level in the car and the intakes carb base is at an angle.

82F100: I have never run that particular setup but just to give you some feedback, I was running the offy manifold with a modified 450 holley and i had the crane(i think, its been awhile) 272 cam. The power band kicked in around 2000rpm and valve float was at 6500 rpm. When i switched to the holman moody intake i noticed a very slight loss of power at low rpm's, significant gains at mid rpm's and about the same at high rpm's, and im sure if there was a bigger carb it would deliver more power up high(and down low)(or all around!? haha). Hope this helps at all!!

I've been tinkerin with the Holman Moody & 750dp on my 272ci.. Not to bad of result's so far 11.30 @ 117 in the 1/4 not to bad, my try to clean up the carb flang on all the spacer (lots of sharp edges in there), and divide the plenum... I did a back to back with the Webers at the end of the day went 11.19 @ 119 in the 1/4, but the 60' was off,the track was going away...Maid one pass with the Webers...

Every once in awhile they show up on Ebay or you can find them at swapmeets.They are basicly a race only intake as the power range IIRC is from 3,500-7,000 rpm.

Couple of questions for you Big Six guys...

Once we get the Big Six aluminum head done, we need to decide what to do for an intake? While the head is designed to use a stock/aftermarket intake, we want to make a high preformance 2V or 4V intake to match the capabilities of the head. With this in mind, I purchased a Holman Moody intake a few years ago off ebay. I'm just wondering if it would be better to do a reproduction of it, as is, or if there are any modifications that need to be done? Or would we be better off doing something totally different, like a triple Weber intake or a twin 2V intake? Since I don't have a lot of experience with the big six (yet), I would greatly appreciate some input from those that do? What would you guys like to see?

For part throttle operation the H/M intake scares me with those huge runners - I worry about fuel drop-out.

I'm perfectly happy with my 2 x 2 intake. It uses (cheap) Autolite carbs.

Why do you think a 750 dominator carb is a good choice? It seems big for the street.

Rich,

For what it may be worth, I used 4 different combos on '75 F150 with only 140 lbs cranking comp,(milled.070) and 260 degree/410 lift on street/highway:

Homemade 3x2
OffyC w AFB
OffyC w Thermoquad
OffyC w Quadrajet

3x2 made best power (if weather was warm), was fun. The Quadrajet got best mileage that I ever obtained. AFB -about 600 cfm- was so so but hard on mileage, I didn't tune on it.The Thermoquad was amazing. I thought the Offy manifold was tops. From 1000 to 5500 this combo was very good--no flatspots,highway passing,etc.

However, the Holman-Moody shows more promise. Everyone should collaborate with Coupe and develope off that with a large carb,maybe as an option, 2x2bbls.

Try it!

FTF, when I asked the question about the 750 Dominator on the Holman Moody intake was inquiring as to me it seemed like a fiting combo.But I'm sure it's probably not the optimum package LOL. Mike had posted in reguards to a new intake possibly based off the H-M for the new head.Maybe something similar in style to some of the slant six intakes that have the same basic sweeping runners with a smaller ID than the H-M intake.

Yes, for the street that makes sense to me. Their 2 x 1 slant six intake is also a good design to copy - but w/ (2) 2Vs.

From what I'm hearing.... you guys seem to be more interested in a high velocity intake for street use, rather than maximum horsepower, so that's the direction I'll take. I've got an idea for the intake, but I need to have some testing done to see if it will work.

With that being said, Rich and I went to an open-house this week. The company we visited specializes in R&D work, including fluid dynamics, real world simulations, and prototyping (3D printing). The technology they have now-days is utterly amazing. Anyway, I'm going to chat with them next week. Should be fun.....

I"m interested in HORSEPOWER not MPG so if you can get the head to flow over 240cfm on the intake and, 200cfm on the exhaust I WILL BUY ONE!!! (my bad)

I think a good choice for a new Intake Manifold, would be like the aftermarket intake for the Slant six. An Aussie speed single 4V. But since the 300 six doesnt have the slant to it, the Runners would be a problem? :hmmm:
83 F 150 SB 4x4 300 six NP 4speed - 89 F 150 300 six Turbo (in works) - 1950 IHC L162 (1&1/2 ton?) - 87 & 88 T-Bird Turbo Coupes - 2000 Triumph Tiger , 76 Honda GL 1000 , & other toys and parts (& junk) - My Gal ? Shes gone... New rule, keep the old junk. Trade the women in as needed !!!

Mike my vote would be a multi-carb intake. A 2-4V is the most versatile. You can run 2-4V on the higher HP set up. But they are also very easy to adapt to run just about any 2-2V set up for street use.

Fcat,
truck looks sharp! any engine pics? In talking with some of the guys who run 240/300's in their SDRA rails. A few are using the H/M intake with a 1" spacer (4 hole spacer with the cone in the center) with the bottom mounting flange trimmed off so the spacer sat lower in the plenum. They said it helped with low end throttle resonse etc.
