Bville intake

[Ol' Ron]

Sometimes things don't work the way you think they should, Developing this manifold, I inlisted the help of my grand sm Ben, He was studding "Solid works: so we came up with some numbers that could be easiely be changed to follow the air floe using the computers flow at 20" inches Vac we mad aover afew dizen shapes. Some Good shapes were beyond my ability to make them. Posting is a problme for me but i got this on our in just a few minutes, I will post the one we decided on and the results of the finished product.

I am not an expert engine builder, but I always thought the problem with Ford flatheads was getting air thru the block, not a problem with intake manifolds. The more knowledgeable folks will chime in from here

Well, I think your right, almost, Most stree intakes make poor race, or preformance intakes as they are in some cases just estic. However the Offy 1076 is one of the best. WE used them with 2gc an late for truck carbs on the Hydro engine. And there are probably others. With that all said the top engines at Bvill usually make a special one, as it only has to work right at the top end. Working with JWL and my drandson we came uo with the next version. I'll post them tomorrow. Might need sone help

Thanks Ron for posting your research findings.

What your grandson's simulation might be trying to point out is that a small diameter nearly straight pipe might actually flow better than a big fat bendy port by eliminating most that big turbulent dead zone and backflows presumably caused by that big fat 90° elbow. You should be able to make a straighter port out of tubing or sheet metal that'll fit inside that big bendy port Ol'Ron. You can do it.

Ron Main and a couple others already did that several years ago.
It works keen.

This was just the first of many computer models to find the best one. Also I had to make it when we did, some times that was beyond my capable hands. However, The computer programing was much faster. Ben could make small corrections just to see what happpened to flow/ Before I started frabracating we made dozens of these. I'm putting that together now.

PS I really appreciate the help I get from others that can inlarge the photos. This makes it easier for others to see the details.
