SBC To Stude - V8 Intake Adapter Plates Project

[Jeff Rice]

Interesting idea(s)...
Delrin would be a tad low, as it melts at about 350f.

Polyoxymethylene/Melting point: 347°F / 175°C

Sintered metal 3D printing could bring a honeycomb matrix that would allow major weight removal from non-stress areas.
Or... CNC pocket milling of Jon's adapters could remove weight, too.

According to the specs. that I read, it starts to get soft at 350°F. I doubt the top of the cylinder heads ever get that hot.
I know of many race cylinder heads that have various epoxy mixtures in the intake ports, and they live without problems.

Hell, MANY years ago, I filled a large plenum crossram manifold with..."bondo"..! It lived for about a year before it started peeling up in a couple of the corners. I think that was more a gasoline problem than heat.

If the plates would have been shaped more like the gasket, or manifold shape, they'd be a LOT lighter. With the CNC machining, not sure why that could not have happened. I know that time is money, and the few minutes more on the mill would have been worth the money.
I suggested it at one time way back and was shot down..!?

Mike,

You are right, time is money, or in this case "chips" is money. I have a hard enough time selling them at the current cost and I don't make diddly on them. If they were selling like hotcakes I would be more inclined to improve them. Sculpturing the edges would go a long way to making them more stealthy as well. I'll take a look at it this fall when I get back to moving forward on the SBC to Caddy version. I looked into 3D printing them in "polysulfone", a pharmaceutical plastic that is autoclavable, good to over 600F. The single set aluminum prototype was $700.00 for the pair just for the material and machining. The polysulfone was $800.00 and little to no discount for multiple parts so you need to be a diehard racer to go that route. Any idea as to when yours will see fuel?

Oh, and as far as weight savings my daughter said I should go on a diet and shave 20 pounds off the car. Just a thought.

Worken in it. Details, need to do some machining.
Have the cylinder head side match ported to my heads, and roughed to the manifold side. That's gonna be a little harder to finish well.
I promise, before I die.

Anyone near me have an Avanti, 63 / 64, that could stop by with it and help me get some real dimensional data on available clearance under the hood? If someone had a car with a non-running motor I could go to it also. I get asked often if they fit under the Avanti hood and I can't say one way or the other. I am in southeast Wisconsin in Fort Atkinson.

I currently have five sets in stock for sale at the old price of $425.00 and that includes shipping. Once they're gone the new price will be $465.00 + shipping. Material cost increases over 2.5 years accounts for the increase.
