I'm new here. I live in Metro-Detroit.
I bought a mystery engine recently and I have been researching exactly what kind of engine it is. I'll add some pictures.
I was seeking a modern power plant for my 1973 Mach 1 and found the Coyote wouldn't fit without severe modifications. I then investigated more modern push rod engines and found one that was advertised as a 351 maybe a Lightning engine. After some investigation I decided that it wasn't likely a Lightning but bought it anyway. More research revealed that it might be one of the rarest engine Ford produced -the 5.8 Cobra R.
The scant background that I was given:
I bought it from a man who became recent friends with a widow who's husband worked for Rousch. She asked for help cleaning out the garage. He put the intake and water pump on the long block then painted it blue for sales presentation.
The supporting material:
F4TE 6015-AA-13 block cast date 4H8 (Aug 8, 1994)
RF-3TE 9K461 EA lower intake (GT40, Lightning, Cobra R)
Rousch did the exhaust for the 95 R
94-95 Cobra valve covers (were black)
Red motorcraft cobra wires dated 1994
block was light blue before he bombed it
GT-40 heads with Crane roller cams
unchanged 3.5" stroke
Block was cast six months before the R's were manufactured on Feb. 19, 1995 which seems long to me.
He said he measured about .3 lift on the push rod when Cobra R's had .47x unless they mean valve lift after the 1.7:1 roller rockers.
No accessories were bolted on but some junk brackets came with that were van/truck style not Cobra style.
One of my friends thinks it might not be a rebuild but an original survivor. inside the crank case there is zero sludge or varnish so it is brand new or newly rebuilt.
There is a good chance that the man was making his own Cobra R clone.
I don't have cam or piston specifics. I'd rather not take the heads off to find out. I can almost get a number off the inside of the piston skirt to research.
I would love to find a 5.8 upper even though the after market ones are reported to be superior. I need to track down Cobra brackets and accessories. I figured that I would keep my thermactor since it seems all there except the pump is seized. I'll also have to change the oil pan and pick up tube to a front sump version.
Here is the link to my Photobucket account:

( Two of these pictures are of an actual 95 Cobra R owned by a friend. The two uninstalled pistons are not a part of this engine)
I'll let the pictures say the rest:
What are some of your block casting dates? Is mine plausible?
Are the came specs (.47x) at the cam or are they measured at the valve(after the 1.7:1 ratio roller rockers?
What other information is there that could help in verification?
Thank you gentlemen.
