Finally finished doing this. I was kinda worried because I know that this is an older engine, and I don't want it to be to far outta spec. Thanks to those who pointed out that the ptu wire is not in fact the best place to put the clamp. Oh and timing is exactly 15 degrees.

On to the next thing...I know the engine is a replacement (first was a fire) how can I date the engine itself?

congrats not having retarded timing!

As far as exactly dating the engine alone. The short answer is: No.

But - you can get close, I believe. You can inspect the plenum and see what type it is. 90-92 plenums are the same. NA lower plenums, heads, and injector style changed in 93 - TT ones changed in 95. 94-95 cams are different than the 90-93. CAS, PTU and some other minor features can tell approximate build date too.

There is also a serial number stamped on the back of the block, but I think its useless.
