SB stroker - looking for advice on engine builder

I am in the market to buy a new 340 stroker engine. I have read numerous negative comments about Indy so I think I will give them a miss.

Anyone had any experience with other builders? Muscle motors etc. I live in Australia so I need someone reputable as its not really practice to fix a problem with a poorly built motor.

Looking to spend around $10,000.

Any advise or horror stories appreciated
