It's a little hard to tell due to the quality of the picture, but it looks like a dual port to me. Look closely at the top of the cylinder heads, There defiantly seem to be two intake ports.

To the best of my info AD code engines are 1600cc engines which were OE from 1stAugust1970 to 31July 1973.VW replacement engines usually had the code AX if I am not mistaken(not cent percent sure)

Maybe the AD code was used on replacement engines from August 1970 to July '73?
Both these sites list the AD code as replacement 1600cc engines

Example:

Information from a 5/73 USA service bulletin issued 5/73:
Engines with the re-manufactured symbol, a letter, a number and ending with X, indicates a VW Exchange engine. Before Oct., 1968 the X was not stamped onto the block.

From April of 1972 Shortblocks were sold with the VW remanufacture symbol followed by a letter. No numbers were used, you were to stamp in the old engine number.

F1 1300/1600
F2 1300/1600
DO 40hp if last digit is "X"
D1 40hp part
AD 1600
AK 1967-1974 1500/1600
AM 1600
AS Sometimes seen listed as Super Beetle case for 1973-onward

Its a replacement 1600cc engine. I had come across similar engines in various colors just recently. Each engine was at an asking price of Rs.25000/- There were about 25 Such VW Engines Maybe this one is from that lot too.

Dear PK,Sorry for the delay in reply, actually i doubt the engine from the lot mentioned by you , as i picked the engine from a lot that came from US as scarp to Ludhiana, this is a regular practice here in Ludhiana, people pik scarp engines,they are drilled painfully by the customs( or what ever related department iam not sure and didn't bother to know as my eyes were on mangoes not trees) i regularly inspect the lots for some luck and was lucky that the drilling in the only vw engine of the lot was done through the shroud, may be the the duty person considered shroud area to be important ha ha,so when i inspected the engine ,it seems to be never dismantelled or too used as u can see how fresh is the gland nut,and its a twin port and 1600 cc no doubt also samba confirms the same, also the flywheel when closely inspected shows very few marks from the starter motor,air deflectors are in super shape and are present which i personally feel that majority of Indian engines lack,so the mystery is for the block in green colour which for sure is painted before assembly as none of the nuts or the push rod tubes have any traces of paint,also the replacement and exchange i think differs a bit and as seniors and samba suggest AD code replacemnt and exchange has X in the end ,this number has a small yet neat vw logo at the number end ,so pls help to know the mystery of green and vw at engine number ending,just to add the remtec after markets too paint engine blocks green,also i got a brand new, yes brand new you can see in pics oil cooler and a external type oil filter next to the engine here are some pics and i will not be using this engine in any of my 6 vw's as all engines are perfect, this will be stored as a back up or an engine for some upcoming projects,Thanks

Sirjee.

Twin carbs can be FUN.

Imagine a Fuel Effeciency of 3 kmpl

If thats whats FUN. Then better not do that sirjee

We are already facing a 8 ~ 9 kmpl Fuel Effeciency, why do you want to further reduce that.
