Engine and head case numbers
Any chance someone can help pin down the engine case and rocker numbers?
The engine case is 901.101.101.7R. Is this from a 1972 car? Assume magnesium?
Similarly, the rocker number is 901.105.111.1R. Any ideas what this was originally? Many thanks.

Re: Engine and head case numbers
Large numbers of head cases on here, probably most with engines too.

Re: Engine and head case numbers
Firstly those are casting numbers.
However, that crankcase casting number identifies it as a magnesium crankcase - could be either from a 2.4 or a 2.7 model.
To narrow it down further you would need to tell us the engine serial & type numbers - stamped on the vertical & horizontal surface to the rhs of the fan housing.

Re: Engine and head case numbers
This picture shows you where to find them:

Re: Engine and head case numbers
And there’s likely a date stamp on those cases too which identifies the casting date to the month and year. I can’t show you a picture like Andys great illustration of engine and type number unfortunately.

Re: Engine and head case numbers
As Mike said, there will also be a date code on the side of the case - just above the casting number already mentioned - see below for location & an example:
However, the numbers are quite small & difficult to see - especially if the engine is in the car - & is often obscured by oil/dirt ...

Re: Engine and head case numbers
It is best if you provide both sides (901.101.102.xR) but with 101.7R I would expect 102.7R. There was a 101.5R/102.7R combo.gturner008 wrote:The engine case is 901.101.101.7R. Is this from a 1972 car? Assume magnesium?
Earliest 7R is in 1973 that I know of. There are some rare aluminium cases with 7R. Best to know the engine serial & type #'s. The '73.5 case is the only 7R case manufactured with the 92 mm spigot diameters and that it was produced only for 6 months before the spigot diameter was increased to 97 mm. So there are some varieties of the 7R case.

Re: Engine and head case numbers
I'll take a look this evening - and let you know the engine number and serial number. I'll also have a look and see if I can see a date stamp. I have the car up on the ramp, so should be able to see it.
The crank case, I think, is from a 72 T. It then got turned into the ST engine I have in the car now. The other numbers on the head/rocker I'll need to check again. But it is possible these are from a later car - perhaps a 73. Many thanks.

Re: Engine and head case numbers
I’ve found the date stamp. It has 76 over a straight line, with 28 below. Above this is stamped three things. G4C.
Am I right in thinking August 72?

Re: Engine and head case numbers
The engine number is 6273836
Does this help identify the engine?

Re: Engine and head case numbers
The other stamped number is 911/85. So, what do you think I have in my 72 car?

Re: Engine and head case numbers
Looks like a 1976/77 2.7S engine case?
