I was looking at a '67 Mustang 390 engine that was out of the car a few days ago and it hat the VIN stamped on the machined surface where the bell housing bolts to the block. the numbers are a bit small and they are just about an inch below the cyl. head surface. They should be visible with a mirror. Drivers side at the fire wall. I hope this helps.

Points to a pic highlighting the area I was referring to. The other area is hidden by the starter (when it's installed) so is harder to see in the car.

Like I said before though, some blocks just didn't have them.

But, that date code you have shows, respectively,
0,B,02,4 meaning 70 (0) or maybe 60?, February (B), 2nd day of the month (02), and the 4 is a change level or in-plant control #. From the sounds of it, I highly doubt you have the original engine, but it's definately not a 352 if the date code is for `70.

The specs for the '63 406 and 427 is part #C3AZ-6250-D and is .500 lift and 306 deg. duration. the higher performance cam is C3AZ-6250-K it is also .500 lift but 324 deg. duration. Both had .025 valve lash. I think there is a source for this cam through restoration suppliers.

At various times during Ford's quest for on the track power they used Isky cams. The earliest that I'm aware of is 1956 when Ford had the very expensive dealer installed 312 cid, 260 hp option. The cam was an Isky E-2 and the same cam was used again in the '57 312 cid, 270 hp rpo engines I think, or it may have been an over the counter part. These cams always had Ford P/Ns. I don't know if Isky had a hand in the design and/or manufacture of the later cams but the E-2 Isky was the base for many fast Fords. The specs are often different as they used different location to measure lift and duration as well as the lobe centers.

John, I have seen lots of info on the cruise-o-matic on the CD. It has schematic drawings, parts info and procedures. I am sure it will work for you.

Thanks for the advice.

Theres no other #s other than 9K30 by the valve stem and a Big #4 in each top corner,is it possible to go by valve sizes or maybe length, hidth, and width of the head=Wayne

Actually, I'm not sure this will tell much (it depends on the exhaust system design).

I'm wondering if one of the heads has a partially-clogged oil drainback passage at the rear of the block. This'll allow the head to fill, causing the rear cylinders on the clogged side to draw oil down the stems..

Which sparkplugs have an oily insulator?

I've recently learned of the value of a leak-down test, too. I've still never done one, but probably will eventually. If I recall, a leak-down tester is about $60.00 (I might be off a bit).

Shoe.

Basically, what a cylinder leak-down tester does is to pressurize the cylinder so you can find out where the cylinder is leaking: such as past the rings, past the valves, or past the head gasket. What have I left out?

A simple or poor boys way of doing a leak down test is to use a screw in compression gauge hose connector and test each cylinder with the piston at top dead center by locking the engine mechanically and applying air pressure to the cylinder. If you hear air escaping into the intake your intake valves are not seating, if you hear the air escaping out the exhaust pipe the problem is the exhaust valve. If you can hear air escaping at the valve cover breather or oil filler you have bad rings. If you get bubbles in the radiator the head is cracked or you have a blown head gasket. You will need to do this with each cylinder if you suspect the problem is only in one cylinder as you need to find the weakest one. Some parts houses have an inexpensive leak-down tester which is a good thing to have in your tool box if you are a budding mechanic. If you dont want to go through all this trouble you can take it to most any good shop and they will perform the test in about two hours. A leak-down test is a good way to determine the condition of an engine, race engines are good at 2% or less, 5% is very respectable for a street engine.
