I brought my 93 Honda D-15 block in for work last year and could not be happier. This is one of the only shops in town that can do an engine his small and this well. After a few minor top end mods this engine Rips! We will be back for the next mod on another D-15 we have, going all out on the next one. We will be back- excellent work K!!

I found Gunn online and decided to take them my parts after hearing positive feedback from some friends. I was building a Chevy 383 stroker. The work I had done was a resleeve of a cylinder, decking the block, performing a line hone, and clearancing the block for some H-beam rods. We also balanced a rotating assembly, flywheel, and pressure plate. My first red flag should have been when they wanted to externally balance my internally balanced crankshaft. The next was when they cut into the bottom of the water jacket when making clearance for the rods. I was told it was a pin hole and that it was fixed, so they moved forward under my approval. I received all of my components back 3 weeks later then what they quoted me and built the motor. Fired it up and broke in the new cam. Found milkshake on the dipstick after shutting the car down. I figured I messed up the intake gaskets so I replaced those and fired the motor back up. Milkshake again, but this time the car wasnt running long enough to be an intake leak. Took out the coolant temp sensor and pressurized the block with my compressor and found out the block wasnt air tight. Called Gunn and they said they didnt pressure test blocks because they didnt have the equipment. Pulled the motor and completely disassembled it. Found that the pin hole was about the size of a pencil eraser and the fix was some Moroso Ceramic Engine Seal on the inside of the block. If you arent familiar, this is not the application for that product. As soon as the coolant got hot, the seal all melted out and the water pump was dumping coolant directly into the oil pan. Called Gunn to tell them they needed to fix it. Their solution, and the third red flag, was to use the same product, just more of it. They were also too busy to get to the block for 2 weeks. I left the block there and started going through the online reviews of Gunn online. There was one review about a customer having his cylinder head held hostage until he paid the shop. From my interactions with Gunn at this point, I realized they were treating me like a regular customer again and I wasnt going to give them another cent. So, I picked the block up the next morning and took it to another guy to fix it. Upon hearing my story and looking at the block, the new machinist had 2 things to say; that he had built hundreds of 383s and never cut into a water jacket and utter shock at the customer service at Gunn. Gunn took absolutely no responsibility and burnt about 100hrs of my time. They also didnt try to make things right at all. Im out 3 sets of intake gaskets, 2 sets of head gaskets, 2 rear main seals, 2 oil pan gaskets, 8 gallons of coolant, 2 oil filters, and 14 quarts of oil. Thats right around $600 bucks of consumables I had to eat. I would strongly recommend finding a different machine shop unless you would like to gamble with your money and engine parts. I will never take them anything again and have already steered multiple individuals into using a different shop. I'd give them less than one star if google would allow it.
