You might have a good one.
Or I might disagree with it .
It would great if you just say whatever is on your mind.
It is all a learning curve.
We all have different experiances to draw from.
As for me, so far I have run with a passion from the Twinks!
It seems the net is overwhelmed with out of phase wheels, cam chest that is good for about 30K.
As I always say "no matter what HD you choose they all come with congenital defects and it is a matter of what you are familiar with and what you want to fix.
The M8 has already had a ration of problems.
My favorite engine case would be a Delkron 4 cam Big twin .
Albeit I have never owned one it would seem to be the best of all worlds.
They are just not available anymore.
Having fully rebuilt both engines, while also not being a professional engine builder but I am a mechanical engineer, the following is exclusively my opinion. I believe the TC is a better overall engine design for the following reasons (in no particular order):
The oil pump is on the inside of the engine
The breather system is actually filtered before it leaves the engine
The cylinder base gaskets aren't gaskets at all but o-rings
The engine actually comes with piston cooling oil jets
The pushrod angles are in better alignment with the rockers
The aluminum casting of is more porous and more prone to cracking and failure on OEM Evo castings
There is more integrity in the mating surface between the engine and transmission
The ignition system is self-contained (no timing cup to adjust)
That's all I can think of right now. Granted there are a couple of small pros with the Evo, but they pale in comparison to the faults.
Just keep in mind, the Evo is based heavily on the Shovel, which was originally designed in the 60's. The TC is new from the ground up (even though a LOT of Evo stuff bolts right onto it).
