I had a performance Pontiac engine built by another shop. When it was time to install the the engine I was still recovering from shoulder surgery and asked Aaron and his team to install the engine. They agreed but suggested I let them run the engine on an engine Dyno. After the first start up the engine developed excessive heat and the dyno run was shut down. Big 3 tore it down and discovered the cam bearings had spun. The original shop to build my motor kept insisting nothing was wrong even though the dyno run showed excessive heat.I was out the cost of the rebuild and would have lost my rear end if I had run the engine that the original builder said was fine. Big 3 fixed it up and it ran great but blew a rear seal. They pulled the engine again and fixed it. Standing behind your work and growing from experience is where Big 3 stands out.Well done Big 3.
