I have a cad file around here somewhere for the spacers and they come out pretty nice. You also need a lifter valley cover. I've made those from 1/4" thick aluminum before, then I think with the gaskets top, bottom and sandwiched between the cover and the spacer they would have to be about 1/2" thick but then you'd want to calculate that exactly yourself.

But then I suspect the height might become an issue. Anthony is right, the real solution would be a separate pattern.

Just to be clear. .Anthony didnt suggest another pattern ....that was my assumption as to what worked best.

He did tell me he could make anything Bill had a pattern for.. leyland P-76 and Rover were it for the little aluminum V-8s.. they also made some MOPAR stuff including some blower manifolds.

Today's exchange rate would be a little under $500 and not include shipping costs. I wonder if Anthony could find a bulk buyer/distributor in the US. T/A comes to mind. If the price was around $400 in the US they would sell like hotcakes. Would be very popular for the Fitech /Holley Sniper TBI.

Yes, the 300 has a following. It is physically smaller and lighter than the 340 and 350, can be stroked to the same displacement and still maintain a good rod ratio, tolerates high hp levels, and can use the TA Rover heads. But there is no good intake available other than the factory ones. These engines were durable and there are many of them still out there. They have especially found favor in applications with small engine bays, and as a small V8 with good power, torque and reliability. It was an economy option with mid 60's Buicks, many of which are still around and being restored by the retro generation, who think of 5 liters as being a big engine.

A year or so ago, I imported an Ford 351C intake from the manufacturer in Australia. The seller required a bank transfer and I got hit with fees on both ends. Add in the shipping cost and I think it added something like $200 to the cost. It might be worthwhile to organize a group buy with shipping to the United States. I'd be in for one with EFI bungs (and EFI rails if he still offers those).

You can also get it with injector bungs to run port injection rather than throttle body.

It's like anything else I guess ... Money Talks.
If some wealthy Buick Rover enthusiast wanted to cover the costs associated with creating a new pattern or a facilitate a bulk purchase I bet something could be worked out.

I have gone through this with some vintage snowmobile stuff that I am into. The particular model I collect had one last manufacturer making belts for it. When no one had ordered any belts for a while they cleaned house and destroyed a number of molds ...one of which was the last existing mold for this belt.
Once it was found out no one could get new ones , everybody wanted one. Right up until the point that Gates gave a quote of $10,000 to create a new mold. To date no one has stepped up with the money. But rather have found workarounds.

I also spent time research and money to send two different water pumps no longer being manufactured for these snowmobiles out to figure out how to get them rebuilt. Had a guy rebuild both types and figure out a way to do that and give a solid price . To date no one has taken them up on it.

We will see how some of this plays out with ta performance now producing aluminum cylinder heads for the Buick 350 and intakes for the Buick 350. It's easy to say online everybody wants one but it becomes a different story when people have to Pony up and actually buy it. Hats off to Mike for following through.

The aluminum 350 heads are a reality and will be here in due time. Seems to me the intakes are available but I could be wrong about that. None of that stuff works for us though because the 350 is too big to be a comfortable fit in the MG (the 455 goes in just as easily).

But the 300 is a different matter entirely. It is a drop-in swap for the later cars and almost as easy for the early ones. Plus they made half a million of them.

Anyway, making a new mold for an intake doesn't cost ten grand. The thing is made of wood fer crissake. Offenhauser used to crank 'em out by the dozen. It's how Edelbrock got their start. Anybody with decent woodworking skills could make one.

To be honest I know very little about casting other than some sand mold stuff I did in high school. I think it would be a lot of fun if someone had the time space and wherewithal.

Here is another idea instead of spacers. This is a Mopar SB intake but you get the idea. Cut the top off a 300 intake and tig the Wildcat intake to that for a prototype for casting for a 300. Dan says the ports match pretty good to the T/A heads.

Thanks to this discussion I spent two hours watching casting and Foundry videos yesterday.lol

I had always wondered how the the cores were made .All we did in High school "Hot metals" class was a flat pattern plate. Lots of interesting processes.

Tony, "visualize" a bottomless intake RV8 manifold = No cores/core box. Loose box casting, pattern is simple to make,(home grown). runners are cast without a bottom ! Heat treat and rough machine head mating surfaces= + .010" ? Port match and weld alum. sheet on bottom. Finish machine head mating surfaces, (warped at welding ?). Good Luck. Art.

Intake arrived today.
While it is a little more complicated than just buying something from Summit. They are still being made and they can be bought.
