Man, everytime I think this bird is finished..... ugh.


Had my engine out a few months ago (mechanic pulls it, I don't) to paint, replace rear main seal, coat headers, etc etc etc.

Starting a couple of weeks ago, rattling/tapping noise in the bottom end above 2k RPM.

We all suspect main bearings or wrist pins. Engine comes out next week.


My engine has been looked at, but not thoroughly thoroughly gone through in the year I've owned it. It runs well, sounds good, and moves pretty well - considering its age, its poor dyno results, and the THM400 + 3.08.

Engine, intake manifolds, heads are stock. Headers and mild cam are not.

Anyways. It is coming out.
At one end of the spectrum of consideration is repair & cataloging the parts. The other end of the spectrum is a 461 stroker kit. A different spectrum entirely is a new engine.

If you had to pull your original 400 for major surgery - would you do the minimum repair and throw it back in?
Or would you take that as an opportunity to work it up a bit? What would you change?
