MK III Camshaft

Hi all,

Anyone know the spec's of the MK III road car camshaft ?

Also when they were sold back in the day, what color was the engine block painted ?

Thanks,
Scott

Scott,
The block was painted early Ford USA pale blue.

I haven't located the specs yet, but in an old road test of the car, the description (306 hp) leads me to believe it was a regular Hi-Po 289 cam.

Scott,

I agree with WDZ. Still a good overall cam, but if you are going to want to go beyond 5K RPM with a little seriousness, go for the LeMans cam.

Thanks Guy's,

Gary, don't worry it's going pull right to 7500. Oh and by the way the margaritas were great

.

Woodzy if you come across those spec's in your spare time I'd sure appreciate it !

Best regards,
Scott

The Ford Tractors of the 60/70 era were painted a light blue ( 3000-4000 etc), when first applied it looks too dark and bright but once its had a couple of heat cycles it seems to adopt a similar shade to the colour your looking for, I do know its what the Aussies used for the GTHO Falcons back in the early 70's.
I have a gut feeling that the 306hp version may have a different cam,but I could be wrong.

In the MKIII GT40 it may have, although the 306hp GT350s used the Hi-Po cam(271hp). The increase to 306 was attributed to the single 4bbl Aluminum intake, 715 Holley and headers. So I lean towards the Hi-Po cam. Now that I'm off the Caterpillar for the day, I'll search a little more.

The engine paint I use is.
Duplicolor DE1601 - Ford Blue
You can just about see the original block colour in this photo

After going through the old article, British magazine Autocar 1972 (Richard Feast,writer), it states that it is the Hi-Po 289 (4.7 litre in Brit talk) equipped in the same manner as the GT350 I referenced in an earlier post. Basic specs for that cam(from an old O.H.O. book) are 310* w/.460 lift( the first Muscle parts book says .450). I would probably get one of the "cheater" or "blueprinted" cams that many cam grinders make for the engine so it can be run as a stock or Super Stock in NHRA competition. The LeMans cam referenced in another post has specs (from the first Muscle Parts book) of 318* in./304* ex. and .510 lift. Odd that within a year or 2 after it was made (C7FE #) they moved to split duration cams that favored the ex., while this one favors the in. These are advertised specs and not at .050 lift as is the standard practice now. If you want I can post all the relevent data regarding the events. I do know that several of the prominent cam companies offer the cheater/blueprinted cams I mentioned earlier and I'm sure they perform better than what the originals did.

This is a D2, a little older than me and runs really sweet....now the starter engine is quite raucous and it's hard to hear the diesel fire up over the starter engine exhaust. It has made moving 30 + truckloads of dirt around much easier than with the little Yanmar :-).

Scott Calabro · 06-10-07, 07:26 PM

Thanks woodzy.

No need to post full valve timing events, I get the picture.

I tease my buddy who has a Komatsu 40 ton excavator all the time.

He gets pissed !!

Cheers,
Scott

Woodz428,

No experience on a D2, but I have run a TD-6, quite smaller, but still a kick in the pants. Amazing the amount of power it has over my 30HP Kubota.

As far as the LeMans Cam, I bought mine in 1972, and the specs were with the cam in the cam box from Cobra Performance.
