MG MGB GT V8 Factory Originals Technical - what Piston do I have?

Hey guys,
I bought a set of pistons for the 4.2L motor that I have in my garage, and I need to know what I have here? They're out of a 3.9L Range Rover, and inside the pistons I find the following numbers:

AE HRC 1827

HEPOLITE 22058

AM 413 75613

Any ideas? If these are the low compression 3.9L pistons (8.13:1) I intend on shaving .090" off the top and .125" off the bottom and using them with my 4.2L crank to build up a good compression ratio (I want at least 9.5:1 if not 10.5:1.)

If they're not the low compression pistons, then I spent $15.00 on ebay (shipping included!) for a set of pistons. I can deal with that!

Thanks,
Justin

A Detroit Piston?

Much better to have a Detroit Piston than a Chicago Bull. ;-)

And all that "Jazz"!

We should probably "Pacer" ourselves on this thread....

But we might miss out on a few "Nuggets" of information.

Your "Cavalier" attitude is really going to "Spur" on the competition...

There is certainly a lot of "Magic" in these posts today....and just in the "Knicks" of time, too!
