Ripped off by A-Bodies member!!!!

Hello. I just found out i was also ripped off by (LFR ENTERPRISES) Mark/Brian Lange. I would really appreciate it if you could give me any advise. They were suppose to build a 340 4 bolt main stroker w/ a eagle 4340 4inch crank. In the process in building the rest on the motor ( heads, crank damper, rockers, lifters, water pump etc..) I realized The crank snout was to small in diameter when the damper slide on all the way. I immediately i contacted Eagle, The specs on my crank if it is an Eagle should measure (1.530) and i measured it at (1.528.). I did think it was a little suspicious when i did get any paperwork on the crank (boxes, receipts, specs). Now! I have to question all of the parts in the motor and even if its really a stroker 4 bolt main. I was charge $4000.00

When i tried to contact them, The number was disconnected i then, looked up the address and number online thats when i ran into all of posting of other customers who were ripped off by these guys.
