Super intakes and tins

[Tony Proasi]

Guys I’m mocking up my 2pc. super engine and have a question about the side tin. Does this gap look correct? I would think it should be a tighter fit between the cut out and the intake.

Thanks
Tony

Hi Tony
Looks like you are working with cover plates for a Normal engine.
Here are a couple pics for comparison - - - - -

Thank you I assumed the normals didn’t have the “arches”
now to find the correct ones.

Tony,
Super tins are super hard to find!
Actually you can fab a patch piece to weld to Zenith tins to create the early super tins'

Thanks for the info that might be the direction I go.

If you look at Tony's 2nd pic the side tin has a "finger" that covers the exhaust port and edge of head. Donald's pics look like that is not present. I believe Tony's is the earliest style, which should also have had a impression for the bolt to hold it to the fan shroud but we cant see that in the pics.

Do we have a clear cut reference when they went from the 1st design ( Like Tony's ) to what I will refer to as the late style ( which is very similar to the rest of production minus the split Solex style of course.

Tony, we have dies to make the late style into the early style like in your pic. We don't have a template for the small intake hump cut outs but maybe Someone could provide a template and you could trim.

Since you helped us with the hood handle for "Walt" at Stoddard a couple of years ago I'd be happy to help weld up or modify some side tins for you if you cant come up with anything.

I'll try to post some pics of the modification process.

Neil,

Thanks for the offer I will let you know. On a side note about the fingers I have also found that the rear tin "breast plate" is different. I will post some pictures when I get home.

[Alan Hall]

Although I don't know for sure, I believe the change to the tin occurred in the '52 time frame. The first 527 engines to use the 40's used adapters on the normal intake manifolds so would have used normal side tins. By the time the super manifolds came along I suspect the tin had changed so I doubt any super tins had the fingers. Tony, what year is your engine?

[Neil Schlabaugh]

Yes, breastplate is matched to 2-peice case dimensions. You can see just a little bit of that in my last pic where the oil breather goes. I should mention that the sides of breastplate has impressions that are different than late also. Fun stuff huh!

[Alan Hall]

I thought the comment about the rear breastplate changing was referring to a change in the 2-pc case engine breastplate. Early breastplates, 1950 and '51 had no stiffening rib at the sides, this was added in '52 for the rest of the 2-pc case breastplates.

[Tony Proasi]

Alan

Its a’53 engine. I understand the difference on the ribs on the sides of the rear tin. I also noticed there are a small square shaped indention that wont clear the early tins. I tried to capture it in these photos. The engine is going in my ‘52 so trying at least make it look right.

[Tony Proasi]

Neil

A couple pictures of the indention you were referring to. Maybe it will help somebody down the line.

Tony, I believe the '52 tin and the '53 tin are the same. Your breastplate looks correct and I think you should have super side tins like Don showed earlier. Have attached a couple of photos of this area on my '53 super with original tins.

[James Davies]

Yeah, the earliest breast plates on the 1950-51 cars have some small detail differences compared to the 1952-54 ones.

I can give you templates for the Super spark plug tins Tony. I might even have an extra set for you. I forgot if my spares are normal or super (or a couple of both).

Neil, the wrap around fingers that follow the exhaust manifold shape were deleted sometime in 1952. Probably early. They are pictured in the 1953 parts catalog, but I have not seen them on any late '52 or 1953 motors. These all had the later (standard?) type.
