Exhaust manifold casting numbers - help


Guest

Recommended Posts

I need help identifying several exhaust manifolds from the late 1950's or early 1960's I have the following casting numbers - for the right side 1618650 and 1634445. For the left side 2205586 and a harder number to read 1674861 or 1674661. Any help would be appreciated. I do not know what these are for and they are NOS

A few months ago, I ran across a new book at Borders that was about engine casting numbers for all makes of USA vehicles. I think it went past the normal engine block numbers and also had intake and exhaust manifold numbers too.

There might be some casting dates on the manifolds too. Generally, Chrysler part numbers were issused in sequence. The 7 digit number starting with the 3000000 would have indicated an initial use for the 1970 model year. 2000000 would have been for 1960. I suspect that 1-series numbers would be for 1950. Usually, there was a smooth progression so that the 2nd digit might indicate the year of that decade too, as 290000 might be for 1969, for example. Again, these would be for the first year's use of the particular part, not the actual later model vehicle it might have been installed on. Maybe this might help you get things nailed down a little closer as to year model?

Hope this helps,

I do not have an extensive casting numbers library nor do I really have any experience running numbers, but in my V8 engine data book 49-74;

1634445 shows to be 1957 Desoto 325 cu in; 1956-57 Dodge 315, & 325 cu in; 1956 Plymouth 274 cu in. All carry the same exhaust manifold casting number. But, 1618650 shows to be a 1957-60 Poly 318. Doesn't make sense that both numbers are on the same manifold. Is one number a casting number and the other a parts number?

2205586 no data. However if the number is 2205536 then 1958-64 350, 351, & 383 shows up.

1674861 no data

1674661 no data.
