Interesting(?) Engine Number...
 

Well, it is interesting to me because I can't find anything in my reference books about it :confused:. Anyone want to take a crack at it?

Engine # = 6520824
Engine typ = 911/57
LHS case = .5R
RHS case = .4R

I guess it is the "5" in the engine # that is throwing me off, I understand the rest.

911/57 is a 72/73 911TV-E carb'ed motor type for the manual tranny and I know having .5R & .4R case halves in the same motor is not uncommon.

Any help would be appreciated :D.

Thanks!

6=six cylinder
5=Euro T model with carburetors (Vergaser)
2= 72 model year

That is interesting since I have engine # 6520935 listed with 901.101.101.4R & 901.101.102.3R cases. Must have been a transition period.

That's it? The "5" just meant Euro "T"? Guess I can call it a day as I already learned something new. Need to get a "book" that covers Euro stuff, I guess :rolleyes:.

Always curious... does that "TV-E" imply 911T, carbed, Euro? I see it now and again in literature but never focused on it too much...

Thanks,

These motors your refering to came originally with Zenith carbs.
