Re: defect in the Merlin III block
 

Not to mention Merlin skimps on the most important ingrediant @ the foundry. Nickel... I had a DEFECT with a head and had a pinhole thru the water jacket in the exhaust port. Drove me nuts trying to find the source of milk shake.

Re: defect in the Merlin III block
 

I worked for World products [Bill Mitchell] and the blocks are no where near the quality of a Dart block big M.The problem with World is unhappy employees because you get treated like dirt, so there is a continual revolving door of different employees.Therefore the quality is in the s h i t t e r!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Re: defect in the Merlin III block
 

MY problem was a casting flaw, not machining. I found out the problem I had wasn't unheard of & decided to let them repair my block rather than replace it. If the new one was bad after I bored, honed, decked, assembled, & installed it again I would have been more than just pissed off. Thought it safer this way.
