I am considering stroking the Cleveland to 408 CI with a Scat rotating assembly. I would like the engine to make more torque down low in the powerband. The compression will be around 9:1-9.3:1 depending on deck height and completed combustion chamber size. I think I found the cam kit too. It is a Comp Cam Magnum hydraulic roller with 224 duration and 566 lift. I am not settled on the induction yet whether we stay factory or go aftermarket.

I would stray away from the comp cams Hydraulic roller set up....... I have had nothing but trouble with my comp roller lifters in my 408.  3 collapsed so far.  Still fighting with them over it.  junk junk!

In my spare time I performed a compression check on the engine. Multiple cylinders with zero compression was not promising for a motor that was supposed to be rebuilt. I decided that I would tear it down to figure out the problem. I am pretty sure the problem is the heads. It looks like the motor has been rebuilt with new slugs in every hole. It looks as if the heads received no attention. I will completely tear the motor apart and rehone the cylinders, check line bore, lifter bore alignment, and bearing clearances.

The heads will get a complete rebuild with Ferrara valves, new valve train, bronze guides, and 3 angle valve. Thinking about some new pedestal roller rockers by Scorpion and chromoly push rods as well. It looks like the lifters are new. As soon as I finish pulling the balancer and front timing cover I will see about the timing chain and camshaft. So far it looks like someone actually used decent components on the build.

Wow those heads are terrible looking. I don't think they ever fired it after they rebuilt the bottom end, if they rebuilt anything.

No you do not have to wait. I looked it up and according to Marti's book Mustang by the numbers I can tell you the following. Your color 4C is Ivy Bronze Metallic and the interior code of GG is only in the Mach 1 Sports Interior and they made 693 of them. You can find the books on Mart's web site or look on Amazon.


When a man is in the woods and talks and no women are there is he still wrong??
