MMMmmm, John I really like that. Do you think it would be hard to make/find a Carrera style fan shroud for a Type 1?

The guys who build these engines must be old, because there don't seem to be any digital pictures of them by them selves on engine stands. WTF?

I have seen a book on these engines and only Chris Reale could appreciate them. They are built more like a watch than anything else, a true work of art by Dr Ernst Furhman. He also was in on the building of the 2.0L engine in our little cars.

I tweek on them as well. I have a ton of pics. email me @ info@aircoledtechnology.com and I'll give you a zip file full. Post what you like here. All my pics are digital, most of them not even 2 months old.

I just got finished with a 59 Carrera GT that raced at Lemans in 60-61..... pulling the engine from a 300K buck car is a true experience.

They sound cool, but they are no fun to work with. I have paid 8,000.00 for a set of pistons and cylinders for one!!! A typical engine build is 25K, can be more.

They are slow- compared to even a 1776 TI engine! The powerband is useless on the street, nothing before 5,000 RPM.....

All they have is a cool factor to me, but after you work on one at least you can add it to the resume.

BTW, someone above mentioned a Carrera style shroud for a TI........

I know of two people currently doing it. Both have contacted me for dyno work on their pieces. One will sell for about 2K, the other is authentic as hell and will sell for around 4K.

$$$$$$$ and these engines go hand in hand. The fan alone is 700 bucks at wholesale.

Pics are on the way....

If you notice some engines have distributors on the upper cam boxes, others have then crank driven. The early engines had roller bearings on the crank and are even harder to work with. These are the engines that have the dizzys on the rocker boxes.

The later engines (starting in 59) had "Plain bearings" like a normal engine. These engines have the dizzys that are driven off the crankshaft.

Either engine is a bitch to set up, even the timing. On the dash of 4 cam cars you will find 2 push/pull switches. These switches disable/enable each distributor. When setting timing you must ensure each dizzy has the exact same curve, as well as initial and full advance. When the dizzy starts to wear this is near impossible.

While the engine is running the distributors are disabled one at a time and the timing is set independantly. This must be done a few times to get the engine to the point that you can disable the dizzys and the idle doesn't drop any noticeable amount on the tach (about 50 RPM)

Sometime in the Spring I plan on visiting Mr. Bill Doyle in Wyoming. He is the modern day expert on these engines and a super nice guy to boot. He has agreed to let me come learn even more about these engines, since he is almost ready to retire. I'm looking forward to it!

Hey Mark,

You might want to look at WWW.KAMMotors.com, it's my old man's shop and he has doing the 4 cam engines since I was born! He's one of the factory trained 4 cam engine builders and if I understand right, there isn't that many out there that can build a damn good engine.

Jake's right...it's sometimes a bitch to build but once it's build right, it's a BALL to drive her...yes, the rpm range isnt great for street driving but hell, try drive her faster, i bet you'll need more toliet papers if you're not careful with your warp speed driving....

There are three different 4 cam engine types, 547, 692 and 587 with it's own version of improvements indicated such as 547/1 or 692/1 to 692/3A etc. The 587 are the street car version and much easier to drive on the street but still not quite easy to take off on low rpm....wait till you get over to a certain rpm range, bang there she goes flying away!

I'd love to drop a 4 cammer in my teen but I just don't have the money to buy such a engine...even in basket case....last time I saw the sale transaction in the '99, a used 692/3A (off of a 904) were in the upper $25K! And it needs to be rebuilt...more moola!

Yes, Jake is right about setting the timing up ....the process of setting the timing right can run anywhere 8 to 16 hours alone! It's matter of experience and understand how it's being set up then when you do more than 5 engines, it becomes bearable....I have done at least 2 myself and it was something...but once it's running, BIG SMILES and more wet pants rides!!!

I don't know how I would be able to even run that motor, the valve noise makes me cringe. (IMG:style_emoticons/default/icon8.gif)

Yes the cam noise is something thats scary the first time that you drive one... especially when you are going up and down through the RPM range without a gearshift. The cams have backlash on the gears so you can definately hear it...

First time I worked on one I thought that the engine was gonna come unglued!

I'd like to build one up with a set of Big Bore Nickies, drop some bigger valves into the heads, bump up the CR a tad and match it to a set of reground cam profiles...

I bet the sucker would make 200 with no problem at all, especially since the rev range is so high!

Hi Rick,

It would be very time consuming...not for those with thin wallets....I include myself in this group. The prices Jake mentions sound about right for custom work.

I'm making a skullcap type piece for my Bergmann POS fan shroud to hide the mounting strap that will give it a similar look. I'll post a picture when I'm done with it.
