I used a Holley "black" pump with a BG regulator and it was enough to get me into the mid tens. Not noisy at all. No return line needed. The Holley regulators are all junk.

The people who designed the holley regulator a
number of years ago were not fluid engineers. A
Holley Blue Pump regulator has a .220 orifice size
which is exactly the same size as two .110 needle
and seats. Interesting! The problem is the needle
and seat design helps transition the fuel to the
float bowls whereas the ball and orifice design will somewhat block the fuel flow. The effective
orifice size is .188 which is below the flow size of two STANDARD needle and seats and therefore
will never keep up with the .120 needle and seats
used on many 600 hp combinations. "Grumpy" Jenkins
figured this out years ago (A mechanical engineer
from Cornell) and if you look in his book you will see that he hooked up two regulators in parallel to supply his fuel requirements. NOT
because he had two carbs! The overall fuel damand
requirement is what you are trying to satisfy.
The New Holley Regulator is an inexpensive design
with the large orifice. 7/16" (.4375) which will
handle any fuel requirement of a single carb in
the 1200cfm range. I can say this because I can calculate the airflow divided by the air/fuel
ratio and come up with a fuel flow (lbs per min) and then look up what the maximum fuel flow in lbs per minute through that sized orifice is and compare it with the Holley regulator .4375 size.
As Goatman says there are many other regulators
which have better machined finishes, possibly
better flow capability, more ports, and are more
expensive. Tom V.

Larry, still interested in those headers?

[Jim Yanoski]

Hey Larry,
Where did you get the nice intake?
Looks really familiar!! [img]/infopop/emoticons/icon_wink.gif[/img]

[Larry Navarro]

yeah jim....looks real familiar doesn't it? [img]/infopop/emoticons/icon_biggrin.gif[/img]

[Jim Yanoski]

I think you will be very happy with it!!
Let me know how it works out?

Jim

[Skip Fix]

Ok Larry the challenge is on . I've got the new tranny in my 78(man was the old one trashed) and its poor performing E head motor. Lets see if we can go heads up at the Southern Nationals!Since you've got thet bigger Dominator compared to my little 850 and Torker II you'll give me some lengths won't you?

[Larry Navarro]

good one skip, so the new tranny won't be an excuse for the mild performance of that less than stellar e-head motor??
[img]/infopop/emoticons/icon_biggrin.gif[/img]
go and get a dominator/victor top-end just to make it an even match, or maybe i should install an automatic in my car, eh?
even with the short time frame till PSN, i'm hustlin' to get this motor done, and if i'm not ready by then, i'm sure dave "torqjunki", will give you an E vs.D challenge.

[Skip Fix]

Now Larry, it is a Larry Navarro - Skip Fix combination challenge,even if you have a round port motor in it.Not a totally D port E head challenge. There are plenty of better E head combos out there that can give Dave some competition. Dave's had a whole lot more than the 15-20 passes my E head motor has on it to dial his in.

You have consistantly made comments how poor MY E head combo runs. Lets see what a Larry Navarro combo can run, not a Dave Sober combination. I think even my little 400 has been down the track faster than any of your 455 combinations.Lets line them up buddy and see!

As you've got the only tall Shaker scoop still in existance its kind of hard to use a Domiator/Victor .

If you think one should use factory heads, I'll say see if you can run fast using the FACTORY Shaker!Mine is.

[Larry Navarro]

whoa skip...on the contrary...this has always been a D-to-E head debate between us, so don't start with the round port "challenge" business.
daves only been running pontiacs a couple of seasons....you have plenty more seat and track time(with all that NMCA stuff) than dave has, so your "lack of track time" excuse won't work, besides 15-20 passes is plenty of time, especially for a "magical E-head" car!
yes...i have made comments on how poorly a S.Fix combination runs, but hey...you haven't given me any proof to say otherwise.....is it some sort of secret?
C'mon Skip, are ya running 10's yet...?!?!?! [img]/infopop/emoticons/icon_biggrin.gif[/img]

[Skip Fix]

No Larry it started out as an E head -iron head. I'll go heads up with any IRON head motor you have in YOUR car vs MINE. Mine with electric windows, stereo amps etc is just running in the mid to high 11s, what's you best? Even 12s?
Even my little 400 was running 12 teens with mufflers and passing a vaccum rule.

Yes that NMCA 400 made a number of passes and had alot of sorting out. This E head motor as well as me has only made maybe 30 passes in the past 3 years since it has been in the car.I'll bet Dave's been there alot more just this year. He's got a great car and fast. He's worked on alot of things to get it faster that worked.

You have been such a round port/ SD guy I have to give you grief about going with D ports.

The "advantage" of D ports over round ports or E heads is the smaller port volume keeps up higher velocity. Your ports cc almost as big as RAIVs! so where's the advantage. I've offered to provide a RAIV and a bone stock E head to airflow against your D ports on any bench even my own, still waiting. Even Dave Bisshop who ports alot of heads will tell you to go racing E heads are easier.

I NEVER said it couldn't be done with D ports, jst the extra airflow give you more cushion to have an imperfect combination like mine. Steve Coombs has been in the 10s with D ports and E heads and is alot faster consistantly with his E head motor.And gosh it too runs 9s on spray.

I got $20 that if we survey all the cars at the PSN in the 10s the D ports won't be the majority.

Shoot I'll even go heads up even with your Dominator!Bring it on guy!

oh no, before it was "gimme lengths"...now you'll run heads up!?!?
what ever makes you happy.

i don't recall the subject title of the original post as "CHALLENGE FOR SKIP FIX".
i think it had something to do with headers.....

Did someone say challenge?

[AG]

Skip, I don't know you, or could possibly have anything against you and my comment is an impartial, non-D-port/E head debate comment. I would be very disappointed if I built your motor and turned your times with the cash you have into it. Compare with Mr. Hands time in the same issue you were in and that says something to me. Again, this is nothing personal, just an unsolicited opinion.

[Larry Navarro]

.....and with that,...i'll go back to the garage.

[Stam16]

AG, Strange you say that, I have and issue of HPP Shoot Out, and the Hand's couldn't even hit the high 11's while John Hoages (sp) TA with a smaller cam, and heavier car ran consistain high 11's, not until the Hand's switched to a Holley Carb ( and on the last run ) did he get into the 11's.

Now the other side of the coin, Skip hasn't had 12-14 years to work out his combination, as the Hand's have, if you add up what he's spent in those 12 -14 years, you could buy 10 of Skips motors, there's and old saying spend enough money/ time and you can make anything run. If anyone thinks a D-port head will out run and E-head the need help.

[boozer]

i am going to go to the pontiac southern nationals. i would be more than happy to hold the cash durring the race catch ya later shawn

[Goatman]

Did somebody say challenge?

I think an interesting comparo could/should be made here. Two 473 ci's, one with D-ports, one with RAIV's. One with a Warrior, one with a Victor. One with a carb, one with EFI. Both relatively heavy street type cars. One runs 10's, one................

Anyone, anyone, Bulher, Bulher.

[AG]

Robert Stambaugh: Skip 11.92, Floyd 11.89, I don't care if it took a Holley. I am not trying to start anything, like I said, it's my opinion. I don't think you could build 10 Skip motors with the $ Floyd has in his 455, can build that motor for less than $2500 doing the assembly work yourself. Skips motor would probably cost at least in the $6000 range, you choose which one you want. I don't care what heads anyone uses, my goal is to go fast and I don't care how. I like the E heads and wish I could afford a set. I would not consider a set if I didn't intend on running 10s. I can't see the benefit of them if you're running in the 11s, any mildly ported D-ports can do that without high compression. None of this is personal, just my way of thinking.

[Larry Navarro]

hmmm.....Mr. GACH,...whos computer are you using?
