Yes, don't quote me on the years but I believe it's 91-93 evo cases are prone to crack behind the lifter block. According to Hillside cycles it's because of the way they cut the cases with a sharp corner.
I called Hillside wanting to stroke my 91 FXR to a 96" he told me "he couldn't do it in good faith knowing it would likely break. Told me to buy a set of S&S cases, send the original motor and then he would send me back a built stroker in 100 hp range.
That's my understanding of it, i'm sure others in here know about those years and that crack.

In other words you will spend less money to have a 120 hp motor than you will to have a 100 hp motor.

The motor was low miles 20,XXX and very clean. It came out of a softail. I can't speak to its maintenance history but I would think if your motor is 20+ years old and hasn't cracked yet you are probably good.

Im looking to upgrade the front brakes. Front end is a dual disk 39mm narrow glide. I can run stock, Ramjet adapters with touring Brembo's, or SK adapters with Tokico calipers. Anyone have any experience or recommendations? Interested to hear if its a big improvement over stock? Thanks

That elevation ain't going to amount to any change.. a .0295 intermediate and a .072 main. Did you do anything to the combustion chambers in the head? Less CC's? And yes a thunder header would be better for that build..
