Thanx for the replys so far...that was quick!

ok...here is what I have on the engine.

On the heads----------D3VE A2A

On the block I found several numbers on the pass side front as follows---58847 and 78H317

I found a tag on the c6 tranny, might help if motor and trans were out of the same vehicle? ---PJD AN4 P14
D8VP B 07168

Hope this helps.....

Hey Stovens...I have not run the motor yet...the truck is still in pieces.....can you do me a favor on those headers.....take a picture from the top and the bottom and send them to me........my stock manifolds are really close to the frame and I am not sure headers will work. Also my steering may be in the way. As far as the Ford460.com I am still waiting for my e-mail so I can use the site....Thanx everyone...I am gonna work on the picture....
