Its a type 3 chassis..a flat motor with twin solex carbs.. it has cannons for the exhaust.
2 questions..
-Can someone post pics of difference size flat motors so I can try and get an idea of what engine I have. (im away and at the moment,so i cant take a
pic of it..)
- What are solex carbs like? are they sort after or not particularly?
cheers

solex carbs not particularly sort after just orig unless they are jetted etc
ure engine could be anything from 1500 to bored out 1835 depends who had it and on piston and barrel size
how long is that rubber band type question jigga lol
want any vw bits old but like me, Made in Germany!!!

i thought that would be the case.. i was told something re: the exhaust exit is a way to tell if you have a 2L or a 1700 or 1800....? eg.. if the
exhaust exits and comes down it means..etc..

if it exits ether end of the heads its a type one base.
and if it exits straight down out of the heads its type 4 but other than that they could be any size the only real way is to measure the piston size
and crank.

Type 3 Engine
Hey Jigga, I did a bit more research for you and found this fairly comprehensive description of both the history and what a type three engine really
is. Your statement that you have a type 1 is probably correct and incorrect at the same time. If it's flat (pancake) and stilll sits under the
engine cover it is definitely a T3 as described here, taken from Everything T2 ( http://everything2.com/title/Volkswagen+Type+3+Motor )
The Volkswagen Type 3 Motor, also known as the pancake motor (a name it shares with the Type 4 motor), is basically a VW Type 1/ Type 2 motor with a
rearranged cooling system. As with Type 1 motors, the engine is composed of 4 horizontally opposed finned cylinders which are cooled by air. The
engine has 8 valves actuated by a central camshaft and pushrods. The engine is cooled by the a constant supply of rapidly moving air as opposed to the
flow of coolant found in most car motors. Oil also plays a large part in cool the motor, and VW air-cooled motors all have an oil cooler. Due to its
air-cooled nature the Volkswagen engine lacks a whole system of moving parts, increasing it reliability. In the T3 motor the fan is attached to the
end of the crankshaft, where the fan pulley is normally attached on the T1/Beetle. The fan rotates at the same speed as the engine and drives a
generator via a pulley and a belt. The air is vented from the fan back across the engine over the cylinders and through a doghouse style oil cooler
that lies flat against the crankcase. Although contrary to popular belief, the T3 pancake cooling system cools more efficiently than the T1/T2 upright
cooling system and does not have problems with fan belt breakage (if your belt breaks, your generator doesn't work. That's it.)
The T3 motors came with several different fuel systems. The earliest was a single centre-mounted Solex side-draft carb. After a few years dual solex
carbs were introduced. These are similar to the Solexes used on early Type 4 powered buses and the dual Brosol carbs now sold in kit form for the T1.
These 32 mm carbs (Solex 32 PDSIT 2/3) gave the T3 an extra boost in horsepower and general improved the type 3 in many ways, including fuel economy!
In 1967/1968 the Bosch D-Jetronic electronic fuel injection system was introduced on North American Type 3s. This system was one of the first fuel
injection systems to be used on family cars. This fully electronic system derives its name from Drucke- Jetronic, as it is metered via the the
pressure/ vacuum in the intake manifold. It was a multiport injection system that later found its way into Volvos, BMWs, Saabs and Caddys. This system
provides superior fuel economy and power and was hailed by the automotive press as the introduction of a new era of fuel supply.
The actual T3 crankcase is basically that of the T1. It shares all internal components and is only different in the location of the dipstick/ oil
filler hole. The hole in the T3 is located near the bottom of the case, but can be blocked of if the case is to be used in a T1 engine application.
The other major difference is the presence of a few tapped holes for a rear engine mounting bracket that sits at the back of the case, similar to that
found in some T2s (buses). Many universal cases come with these holes, and a block off plate, allowing the crankcase to be used in either a upright T1
motor application or in a T3 pancake engine application.
T3s initially came with motors of greater displacement and horsepower when compared to T1 and T2 upright motors. T3s got the first 1500cc motors
(hence their true model name, the Volkswagen 1500) with the 1600cc motors following soon after. The Type 34 Ghia came with different motors that had
different pistons that produced a higher compression ratio than other Type 3s.
They all look basically the same, and you can't tell the size of the motor i.e. displacement (1500, 1600, -2400 cc) just by looking at them. The only
way you can tell is by measuring size of pistons etc, and to do that you need to pull them apart, and that is another story. If it's working and not
causing you any hassles, best just decide it's a 1600 and treat it as such, unless advised otherwise.
Hope this helps.

If it has twin Solex 32PDSIT which are the normal stock carbs then it is very likely the normal stock engine. 1600cc.
You can't really tell the different engines just looking but if it were changed then it would have also likely had the carbs changed too.
Since the original carbs are still there then I reckon it's stock.

type3 look like this
this ones missing the generator but with a type4 the first noticable difference is the alternator is on the opposite side
