3.4 physical sizes

[Jim Reym]

Hi everybody. First of all, don’t you just love the internet, it’s like some super intelligence thing. Anyway the project is a tribute build honouring the Alfa Romeo Type 33 as in my avatar. At this point I’m contemplating the build and planning the bits and pieces. I’ve looked at many different engines and based on the variables seriously thinking the 3.4 is a very good match. The way the intake is mounted, being it’s transverse in the car really won’t work so that needs changing and I’m looking at ITBs. That aside the power numbers are in line with the original cars stats so the chassis will feel comfortable with both torque and horsepower. Thinking of custom building the ITBs in aluminum with a CF box on top just like the Periscopio model of the Spider version of the 33, ITBs kick ass in the looks department I think it’ll wake the engine too.

Anyways, to the subject matter. I scoured the net looking for the physical dimensions of the 3.4 and haven’t had any luck. If you can direct me or have those numbers I’d really appreciate hearing from you.
Thanks

My engine is on an engine stand. It has no intake, exhaust or accessories installed. It is 22 3/4" long from the back of the block to the face of the crank pulley ( no water pump installed). It is 22 1/4" wide with no accessories or exhaust manifolds installed. It is 22 1/4" tall from the bottom of the oil pan to the top of the cam covers (no intake installed).

There was a set of measurements on here for a project car in 2007. the member was Motoman991 and I haven't seen him on here in a long time. However if you go to the top tabs between your screen name and alerts tabs there is an inbox tab with a drop down. Click on start a conversation enter Motoman991 in participants and drop him a line. The messaging function sends an email to the email address we used when we signed up to join the forum. He might still use that email and respond.

https://shoforum.com/index.php?threads/engine-dimensions-and-some-questions.80516/ This is the thread with his measurements. They were included inside his photo with the colored lines that I can not see clearly anymore. Post #11 in this thread

Hopefully someone has an engine with the dimensions to include heads, intake and exhaust manifold space requirements

That’s great, Mucho Gracias

Just curious, have you given any thought to the ECU?

Yes I have. Using the OEM PCM has some advantages but only if theres a VIN to go with it however theres a standalone that looks pretty good. I was curious aboutMegaSquirt and wrote them and they got back to me promptly and said they can provide from mild to wild and everything in between. The price depends on the specific tune but seems reasonable. Their ECUs can drive whatever gauges I want too.

With the stock ECU you have lots of options. SCT has full on tuning to piggy back systems like STRK's TweeCeRT.

There are variations between the different years ECU's not to mention different functions existing in earlier years, that were removed in latter years.

Were you going for the A4XN or the manual tranny?

I like the Porsche 987s five speed transaxle, it’s an open diff, very light and a good match for the output of the 8 Theres a good possibility of having an engine and PCM from different cars with an unknown VIN on either. I don’t know if it’s possible to reflash the PCM without a VIN. That’s why I looked at MegaSquirt as a stand-alone. But if you know otherwise I’d like to hear from you.

EEC IV Inner Workings

Although people like to disparage the Ford OBD1 engine management system, it was good enough to make it into
F1 racing in the late 80s.

The above write up is Mustang centered, but displays its method of operation and some of its capabilities.

I am not sure these early Engine Management Systems are tied to a VIN.

There are threads on this platform that show how to manage installing the engine into another chassis.

You're posting obdI and threads about other chassis installs. This is obdII and much less common v8 swap.

I had a look at that and also googled to learn some more on the subject and here’s what I learned.
It is possible to get a generic VIN online and there are several tools in addition to Fords stuff to program the Ford PCM.
The Ford on-board computer has a few modules that interact and control different functions and the PCM is one of those modules. There are several decent scan tools on the market that allows a peak into the computer and to make light changes and read and delete codes.
I think the kicker for me is the vintage of the electronics, I’m pretty sure my IPhone 7 has the computing power of a 90s mainframe so why would I go back in time? The quality of the engine sensors too are much better now then in the 90s and because my needs are strictly engine management then I believe it behooves me to go with the most powerful ECU I can find and that points to the Aftermarket.

It is possible to program the VIN and get firmware online using the right OEM ECU programmer (forget the model / standard). Dealers/Tuners do this all the time, and depending on your local inspection requirements is needed to be matched up. I don't have the information at my disposal at the moment, but can get more by the weekend if someone else doesn't get it first.
