Collaborative early a experiment

I have been thinking about this for some time now and finally got around to doing it. I'm looking for a volunteer/guinea pig/associate. Here are the qualifications: You must live withing 1000 miles (more or less, will explain later), you must be innovative and unafraid, you must own an early A (preferably 65/66), you must be installing or using a small block (preferably non-poly, not sure how the exhaust would seal), 70s and up smog heads are preferable (more exhaust sealing surface), you must know how to fabricate or at least solve mechanical problems, your car should be automatic (preferably console, although auto column shift may work), must have manual steering and you must have a way of taking and posting good pics here on FABO.
Now that we've weeded out those who do not qualify (there can be exceptions) I will explain. I sell manifolds, many FABO members have probably seen my ads selling 340, 360 magnum and Dakota manifolds. But this post is NOT about selling manifolds, it's about helping early A body owners. I have no problem selling my manifolds..the only problem I have is keeping them in stock. What I propose is this: I have had many, many early A owners ask if my 340/360 manifolds will fit in their cars. I tell them that I have seen posts by other members who show that "some" of these manifolds will fit in an early A. I say "some" because there are two different castings of the LARGE HOLE 340 driver's manifold, this is where it gets interesting....the late 60s 340 driver is designed sleeker and less bulky than the 70s 340 manifold (see pics). The late 60s 340 rises up quicker and higher than the bulky 70s 340. It also pulls away from the steering box more than the 70s 340 and has more clearance in the steering shaft area. For these reasons I'm looking for someone who would be willing to attempt to install and document the use of the 60s 340 manifold along with one of my "machined" 360 magnum passenger manifolds. This is a unique chance for someone to get a lot more exhaust flow with very little risk. I say very little risk because I had to spend hundreds of dollars to find the manifolds that work best for the 67/68/69 and up A bodies. I lost some of that money because some of the manifolds didn't work out. I propose to find the right person (persons) to buy (temporarily anyway) a set of these manifolds, install them in their early A, and document it as best as possible here on FABO. What's in it for you???? Good question!! If it works out you will have a set of the best flowing cast iron manifolds you can get. What's in it for FABO Early A members??? They will know, with no uncertainty that the late 60s 340 will work in their cars and what (if any) modifications are required. Yes I know, others here are going to say, "Yes, it's been done" or "Yes, I did it to my car!!". I just haven't seen it documented in a way that reassures others that it's doable without making too many changes or without having to spend unreasonable amounts of money. I can not, in good conscious, sell the late 60s 340 to an early A member and let them waste their money on a manifold that will not work. What's in it for me??? Another good question. Not much really because ALL the manifolds I sell will fit the 67 and up A bodies and I will sell them whether the EXPERIMENT works or not. My purpose is to give early A owners access to better exhaust options without having to spend a fortune on headers.
So, the person I pick would have to be willing to pay for the manifolds up front along with the shipping costs. If "FOR ANY REASON" they don't/won't work (must be documented for others to see) I will refund the cost of the manifolds and pay for shipping back to me so I can resell them to someone else (67 and up A bodies). Of course the manifolds must be returned in good condition for you to get your money back (no cracks/breaks/damage). What does the buyer have to risk??? Well, he/she will have to be willing to absorb the cost of shipping one way, JUST LIKE ME!! So it comes out even Steven, I lose the shipping back to me and the buyer losing shipping to him/her. I am willing to lose the shipping costs to help other early A owners get better exhaust. Pay Pal will allow a full refund within 30 days with no penalty, but I will not hold the buyer to the 30 day window.
The reason I'm looking for someone within 1000 miles is to keep shipping cost down for both of us. I don't like losing money any more than the next guy!!

To the FABO moderators..if my proposal is improper or violates any forum rules please let me know and delete this post!!

Lastly, I know I will get some suggestions from others who have done this before (at least I hope I will) which should give the "volunteer" some incentive. This post is only about using the late 60s 340 manifold ONLY so please keep it real. If you can show any problems you ran into and how you solved them it would be great. My only purpose here is to help Early A owners, voluntarily losing one way shipping costs isn't something I normally do.

Thank You and,
Let the games begin..............
