Jason,

Welcome to the Type 3 world.

Under the assumption that you're on the Type 3 email list, I'm 
forwarding this to the list, too. It's always best to send questions 
to the whole list, rather than just to me.  

There are many things about the Type 3 engine that are exactly the 
same as beetle engines, but there are also some significant 
differences that require you to buy the right one. Here's a short 
list of SOME of the differences that I can think of, but others may 
be able to add more.

1) The type 3 case has a different dipstick arrangement, requiring a 
different hole in the case.

2) From 69-on the type 3 case has provisions for a rear engine 
support that beetles never had.

3) The type 3 engine puts the oil pressure switch in a different 
place.

4) Type 3 engines mated to an AT have a cutout in the case that 
allows access to the torque converter bolts.

5) Type 3 cases have a different mounting stud for the oil cooler.

These are just the differences in the longblocks that I can think of. 
>From there on out, EVERYTHING is different.

If you're in the US, your '73 was originally FI and has been 
converted to carbs. It's important to understand that carb 
conversions are iffy things that most people will never get right. 
There's a lot of work that needs to be done to get the jetting right 
that most people never do, simply because it requires skill and time. 
There are people on this list that may be able to help you with this, 
but it's NOT safe to assume that it's all okay on your car.

And, if you're in Calif. I don't think you'll be able to renew your 
license with the carbs in there.
