I had several bad experiences. I had several things did a couple of years before I actually built the motors.These are pulling tractor motors.Two separate heads. The first one was a recheck. It came back with the wrong valve springs and a bent valve, which Im sure it had when I took it.The 2nd one did not get ported out or oversize valves like I requested plus one valve seat was machined out to big and it dropped the valve and got my piston.Then there are two cams I had to replace that they ground I requested a low rpm range on the torque and I got two that sounded like drag cars when idling. They would choke out at the drop of a hat. Switched cams and it was the difference in daylight and dark. I also took a crank to be stroked, with the rods, pistons and flywheel to be balanced also. Put motor together and it shook so bad it felt like someone beating it with a sledge hammer. Every bearing in it was beat out less than two hours running. In all fairness the crank was stroked and balanced correctly.But nothing else was touched like I requested. The problem was the reconditioned rods that I bought somewhere else, they were not right. If they had been balanced like I requested the defect would have been found and easily corrected there.I don't know if the machines were not right or someone didnt or know how to set them or what.I just know it has cost me a small fortune to have to have almost everything redone not counting all the labor in tearing the motors back apart and rebuilding them again. They definitely need a quality control department because they damn sure can't have one and if they do it absolutely sucks!
I brought a 2003 dodge ram block, head, and crank there to have machine work done on it... i also PAID to have 2 cam bearings installed, i never looked at it until yesterday and BOTH bearings HAVE NOT been changed!!! BUT i was charged for services not delivered!!! How do i know this???...> before i took the block to somerset i marked one of the bearings with my punch on the rear bearing... oh sure that bearing was removed ...BUT it was turned around and reinstalled so i wouldn't notice the punch mark... so in other words Cornett Machine screwed me out of some money...i have photo proof of my engine including the punch mark i made prior to bringing it there... and here is the same punch mark on my bearing but turned around...All i can say is IF you get work done there take photos and check it good when you get it back, i rate them 1 star only since i can't give them a neg star...
