Muscle motors mopar """" BEWARE"""""""

It is interesting that they ship out of Lansing, MI as that’s where Muscle Motors was located. Maybe they are still building a few.

From what I remember. IIRC, “Ken” of MM was having family issues on a large scale and wrapped up the biz suddenly to take care of the family first. What we “MAY” be seeing here is the last of there inventories being sold.

interesting read , though not the first time I've heard horror stories about MM. no sweat here, I wouldn't do business with them anyway, nor would I send that kind of money out into space without some kind of protection. as for paperwork, they could provide any kind of paperwork, that doesn't in any way guarantee it belongs to that specific engine, this is why I do and will always put together my own ****, so I know for a fact exactly what's there, and if it fails, I can't put it on anyone but me.

I haven’t heard to many great stories from people dealing with Muscle Motors myself. While there rep isn’t as bad as Indy cylinder head, it isn’t a good rep like Mancini racing or BluePrint engines.

To the OP, I’m very sorry this fiasco is taking place.
To error on the side of caution, disassemble the engine and check it out carefully. Then run it. On a dyno would be great BUT don’t get caught up in the numbers so quickly since we don’t know what dyno they ran it on or how anything else was done from start to finish.

Perhaps everything is actually OK even though everything prior sucked. Best of luck.
