Location: Dalveen, Queensland, Australia | There's a bit of a move to try and get Edelbrock to make one of their new-ish RPM Performer Air Gap manifolds to suit Poly 318s.
This would mean that a much higher performance manifold would be available for the whole range of Polys, would it not? Not the very earliest ones, but the 313s, 318s... 303s as well? That's a lot of cars in the Forward Look years, true?
Gary Pavlovich is approaching Edelbrock following my nephew's suggestion that it could work. Gary thinks there's a market for them that would make it worth Edelbrock's while to do it.
Here's an article about testing such a manifold, which shows that it has a huge torque spread on other engines:

Here's Edelbrock's page on the present range:
http://www.edelbrock.com/automotive/man_chrysler.html
Can we have some kind of indication what interest there would be from members of this forum in such a manifold? With power from 1500 to 6500rpm, it sounds good for both street and strip. |

Both are IEIEIEIE designs. The SBF is narrower than the A-poly, so the runners could be extended into a new flange design.
Might save some design/development time for Edelbrock.

Location: WHEELING,WV.>>>HOME OF WWVA | RAY---------if i'm not mistaken-EDELBLOCK should have intake design specs. from their old line------anyhow-i wrote them a letter about 2 yrs. ago-about presenting new intakes for the poly------at the same time-i asked about the possibility of their finned aluminum v-covers being reproduced---------------got no reply----------maybe they're too busy with the chevrolet and fomoco products---------------later |

Location: Dalveen, Queensland, Australia | That sounds interesting... though I'm not sure what IE IE IE IE means...
One of the obstacles I see about this design is the need to get the water tracts below and forward of the two leading runners without blocking the air or transferring the heat.
I gather by looking at the pics that the Henry engine has the right hand bank staggered ahead of the left (ie the foremost rod on the crank is for the right bank) while the 318 is the other way round.
Chuck, like I said, Gary Pavlovich has dealings already with someone in the company and might get their ear... anyway, it can't hurt for others to be chasing them up.
No doubt they have plenty of detail on hand to make it all happen.

You could be correct that the Henry engine is leading with the other bank. Hadn't given that a thought in the previous post. IE translates into Intake/Exhaust, IE IE IE IE would be a poly (or Fomoco) valve layout. A SBC has the 318LA pattern of EI IE EI IE on a bank. |

Location: Dalveen, Queensland, Australia | Ah, I would never have thought that way about the IE IE business because I regard the Poly as a hemi-type head, I would have just said 'has even spacing'... which, of course, the IE IE IE IE arrangement give as well.
Not forgetting that a lot of this stuff is done on computer, it wouldn't be hard, I wouldn't think, for them to mirror the F**d design to get it right for the Chrysler engine. As far as the runners go. |

Location: WHEELING,WV.>>>HOME OF WWVA | i would think if there was to be one person that could possibly get the ear of the EDELBROCKS it would be GARY
i get a kick out of watching one of the EDELBROCK sisters-CAMMY(yes her real name)on one of the car rebuild shows-helping and getting her hands dirty-with the installation of one of their crate engines----------------later |

It would be nice to think this would come off... I've posted similarly on the vintage section of the Moparchat forum today, might do something at the Dodge Talk forum too. |

Location: The not-so-great, dirty-white North ( Michigan) | I twould be real interesting if Camille (Cammy) Edelbrock would do a manifold and they could get an episode (or more) on one of the rodding shows with a Edelbrock/Pavlovich poly buildup and dyno test.
I would be interested in what the results are (in HP/in^3) versus the standard crate Bowtie SBC or similar displacement, CR and camming.

This chart is quite demonstative:

Location: Dalveen, Queensland, Australia | Gary Pavlovich reckons they'd sell twenty a month... so maybe more than a hundred...
I doubt that they'd run a batch of 10,000, and in this computer age the patterns etc will be very easy to set up.
Let's be a little bit optimistic for the moment, eh?
Frankly, I reckon I could make the patterns for these myself. Though I simply wouldn't have the knowledge to ensure the flow rates they can give. |

Location: Dalveen, Queensland, Australia | Well, I gather there's no word back from Edelbrock...
If nothing happens there, I think I'll make up patterns to cast something myself. |
