Hey all,

I have a lot of experience with Type 4's. I know these are fairly similar. Just trying to get some info on this engine.

I recently had a lead on a $50 type 1. Been sitting in a garage alone for years. I grabbed it no questions asked. She is clean and turns free, no end play. I will throw a carb on it and see if it runs.

AE engine code, Single Port.

Everything I can find says AE would be a 1971 dual port. Does single hint that it came out of a bus?

Also:
Just a few questions, maybe to confirm the source, and year. I will likely keep this, and rebuild it for a reliable heart for my 912.

What is the hot ticket, reliable, cool running and good MPG build out of these?
I assume 1776 or 1911 with a "cheater cam", dual carbs, etc.

$50 is a great deal.
Check out the engine builds thread for ideas.

1970 bus was 1600cc single port, engine number starting with B, like a 1970 Bug. AE case means likely is 1600cc and someone swapped out the dual port heads, intake, shroud, oil cooler, etc for a different engine.

I did somewhat opposite in 1976: I made a 1600cc single port engine into an 1835cc dual port.

Interesting.

To me... at least with my research, it seems a bit oddball to swap out everything and go TO single port. I see they are popular among dune buggies, though. And have some of their own benefits. (as opposed to DP)

Might be beneficial for me, could be recently rebuilt - probably is being as clean as it is.

From your photo showing the 12 volt voltage regulator mounted on the fan shroud, I suspect the engine WAS used in a fiberglass dune buggy.

Not many buggies use heater boxes and a stock muffler.

Don't try to read too much into it, Likely someone needed to build an engine and found a decent case to build up. The factory case number is mostly meaningless.

The single port gives a lot more low end torque. Probably used in a 67 bus.
