sym dd50 vs af16e block

[Dr_Craw]

so I've got 2 engines to work on and have a question
Which one is better suited for modification?
the sym dd50 or an af16e pulled from an elite
will probably keep the stock crank on either setup but with
with a 72 kit and pipe for either one
any thoughts?

thanks

Either one is fine.

Just make sure you do the intake windows.

Comes down to which unit you are able to get replacement parts for easiest.

I was always under the impression the parts are almost completely interchangeable?
the question is how good of a reproduction is it?

As Red EFT said: both are good for buildups, just need to keep track of the small differences between them and make allowances for it.
almost all parts with few exceptions are interchangeable, similar to the slight differences between the AF16s and AF18s as AF18s weren't really for the US domestic market
the DD50 is a good repro; there's many DD50 builds here in Hawaii, maybe perhaps more than AF16s as they have stopped making the AF16 and are still importing the DD50s

Totally agree here. If you're in Hawaii I'd say go with the dd50 because they're still being imported and there's lots of parts available. Not sure what you guys have in canada but I feel like the af16/af18 would be more accessible in canada than the dd50.

The dd50 has a weak stator side crank case. They crack easily. Personally I'd stay away from them.
You can use an af16e case with the af16 stator and flywheel I've been told by my HI people.

mkay thanks for the info folks
