Here is my story and opinion:…read more I feel these guys are crooked. I took TWO, four bolt main 350's in and they said both were cracked. The first I agree it was cracked. I suspected it when I took it in. The Second however was a clean unpainted block that was just cleaned and magnafluxed 1 year ago. PERECT Block, but neede to be bored .010 over. This from a machine shop I had used in Wichita KS, very frequently. I take it to E and E and they immediately sarted salivating over this block. 10 working days later they call an say it's cracked too!! Sensing I'm being scammed I go to the shop to look at the block. ITS PAINTED BLACK. I said that's not my block and he says "yes it is, t's got your name on the side" written in a marker by them! I argued and they treatened to call the cops for disturburbing the peace. MY BLOCK WAS NEVER PAINTED!!!!! I asked them if they painted it and they said "no". I striped this block down to bare metal myself!!!! Where did this painted block come from? AND where the heck is my BLOCK????? The more I tried to ask him, the more they insistedI leave their shop!!! IF I WERE YOU, I WOULD TAKE MY MACHINE WORK SOMEPLCAE ELSE.

I'm sure at some point Clay's was a top shelf machine and auto parts shop. In my experience, it's…read morenot that anymore. It's been almost a year since my dealings with Clay and JR and felt/feel completely fugged-over by them. I've since chalked it up to lesson learned and moved on to another shop. GOOD: courteous and extremely knowledgeable staff. Machine work prices are fair and the tolerances are accurate. Also, they're no strangers to classic engines - which is rare. Background: 1963 Cadillac 390. Stock, spare no expense machine and rebuild. I spoke directly with Clay and requested that the engine block and heads get hot-tank cleaned and carefully inspected for cracks or damage. If ok, check dimensionally. If ok, a quote including parts, labor, and necessary machine work. Clay agreed and recommended machining the heads to accept newer-style valve guide seals. I agreed and asked for an estimate on turnaround time but I made it clear I was not trying to rush. Clay committed to getting a quote to me the following week and that, if I approve, the work will be done within a week or two after that. I paid for the clean-and-check up front and left a deposit for machine work. Then it all went downhill from there. BAD: I didn't hear back for several weeks. When I finally called, I spoke with JR. He apologized and explained that Clay is only in the shop Tuesday-Thursday and that he didn't know what Clay was doing with this project but that he would give him the message and he'd surely call me back. He didn't. This cycle repeated for close to 4 months. Not one call from them to me. Not once. When I had a belly full of it, I called called and said I'd come pick up my parts. Suddenly, not to worry, my engine would be ready for pick up in 2 days. 2 days later, I take time off work to pick up my stuff (not open weekends and they close at 5) before they close. I do a cursory look over everything, looks good, and load everything in my work van and pay the balance. All-in the tab was just shy of $4k. Yes. $4,000 for parts, machine work, and labor - no assembly. If you're thinking part price drove this price, they didn't. A complete engine rebuild parts kit from a reputable source with quality parts is around $1500. Ok, I DID said "spare no expense" right? So I would not squeak if in return for my money and long wait I received top-notch work with quality parts. Nope. The block and heads looked great! Fresh and clean cast iron with fresh valves on the heads! So what's wrong with that? For starters, the valves were new but the springs, retainers, and seals were not. Remember those new-style seals Clay sold me on? Nope. Old style AND old reused seals were reinstalled (pics). Second, the fresh cast iron look was not because they were clean. It's because they were all spray painted with cast iron paint!!! Over grease blobs too. So now I'm really mad and look deeper at the work. Since I now know that the fresh appearance comes from a rattle can, I suspect that the block/heads were NOT properly hot-tanked as promised (and charged for). I turn my attention to the block/head expansion plugs and see that they were never removed. Just painted over with iron paint (which I now have to remove to repaint in the original color). I scrape away the paint around the perimeter of one of the plugs and my pick pokes right through - rusty from the inside. The plugs weren't checked, much less removed. Removing them revealed cooling jackets fully clogged with years of gunk and debris - the reason for hot-tanking an engine block and heads in the first place. I ended up taking my engine block and heads to another shop that fully cleaned and re inspected the block/heads before assembly work began - costing me even more money. Eventually, called Clay's and JR answered. I asked why parts were not hot-tanked as promised and he explained they don't have a hot tank at all. Just a commercial parts washer. He didn't have an answer for the paint. Oh and the new oil pump gears are two different sizes. Can't use. Another $150 I'll need to spend. Clay's never again. Ill post receipts soon. BEWARE!

Clay's it top notch. There is no one else I would trust to work on my motors. They have forgotten…read moremore than most machine / engine shops will ever know. They built the motor in my 57 vette. Instead of telling me that they could not weld my cracked blocked they took the time to not only weld it right but also helped me chase down an oil leak issue at my house once the motor was back in the car. The top rear galley plug leaked when the motor got to temerature. It would have been easy for them to tell me this was not their issue as they were clear when taking on the motor that their was no guarentee due to the orriginal condition of my motor. Instead both Roger and Clay took the time and effort to help me figure it out. They are currently machining and building my straght six 235 for my orriginal 1955 Cameo. HAPPY Customer. Lex.

I recently took a Pontiac 400 block to them after the original cast crank snapped.
