I have been ripped off by this shop. Billy also know as William Rollins had tuned my car for a very good deal and i couldn't have been happier with the experience. About three months ago i decided to have billy build a 4.6 for me because i have heard nothing but good things about him. Boy was i wrong. It has now been three months since i gave billy the payment for my engine $1,400 and i sent him cams worth $350.00. Just half the cost of the engine. He is no longer responding to my phone calls text messages and it seems like his phone is no longer accepting phone calls. For two Months he was giving me the run around saying his shop got broken into( long story) and that the machine shop didn't machine the pistons correctly and now this. If anyone knows of a way to contact him or anything please let me know because my money and parts has been stolen from me and he is running bad business practices. Please post on other forms also to get people to stay away from this shop.
