405 Engines & More in Oklahoma City: Engine Rebuild and Machine Shop Work

405 Engines & More is a machine shop and engine rebuilding specialist located in Oklahoma City that handles everything from basic machine work to complete engine rebuilds for domestic and imported vehicles. Unlike general repair shops that outsource engine work, this operation performs diagnostics, boring, honing, and assembly in-house, which means faster turnaround and direct communication between you and the people rebuilding your engine.

What 405 Engines & More actually does

405 Engines & More focuses on engine machine work: boring and honing cylinder blocks, grinding crankshafts, resurfacing heads and blocks, valve seat work, and complete engine assembly. They rebuild engines for street cars, trucks, performance builds, and older vehicles. The shop also handles diagnostic work to determine whether an engine is salvageable or needs rebuild versus replacement. Because they operate as a machine shop rather than a quick-lube facility or general repair garage, they do not do routine maintenance, tire work, or body shop services. You bring them a core engine (your old engine) or they source one, and they rebuild it to your specifications.

Services and pricing

405 Engines & More charges on a per-job basis because engine work varies widely depending on engine size, damage extent, and performance level desired. A basic engine rebuild (new rings, bearings, gaskets, and honing) typically runs $1,200 to $2,200 depending on engine displacement; stroker conversions and high-performance builds run higher. Machine work alone (boring, honing, head resurfacing) usually costs $400 to $800 per piece. The shop requires a core deposit to begin work, typically $300 to $500, applied to your final bill. They accept both drop-off and customer-supplied cores. Turnaround is usually 2 to 3 weeks for standard rebuilds, longer for specialty work. Call to confirm current pricing, as material costs fluctuate.

How it compares to other Oklahoma City options

Most independent repair shops in Oklahoma City send engine work to an outside machine shop, adding 1 to 2 weeks to your timeline and a middleman markup. Dealership machine work exists but is limited and expensive; they typically recommend engine replacement rather than rebuild. Shops like Edmond Engine Service offer similar in-house machine work but operate north of the city limits, making 405 Engines & More more convenient for central Oklahoma City residents. The main trade-off: general repair shops (Firestone, Valvoline) will not touch engine internals at all and will only recommend replacement. Choose 405 Engines & More if you need serious machine work, have a salvageable core, or want to go the rebuild route instead of buying a crate engine or used replacement.

Who it suits and who it doesn't

405 Engines & More is right for DIY enthusiasts rebuilding a project car, drivers whose engines have failed and who want to rebuild rather than replace, and people restoring older vehicles where finding a matching used engine is hard or expensive. It is also useful for performance builders who want custom boring, stroking, or porting work. It does not suit people who need a quick fix for a daily driver (a remanufactured engine from a parts house will be ready faster), those without mechanical knowledge (you should understand what rebuild option you want), or anyone uncomfortable managing the core deposit process. The shop is not a general repair garage and does not offer the hand-holding of a full-service facility.

What the first visit involves

Call 405 Engines & More with your vehicle's year, make, model, and engine problem. If you have the engine out already, you can drop it off; if not, they can advise whether you should remove it first or have them evaluate it in the car. They will inspect the core, run a quick assessment, and give you pricing and turnaround for your specific rebuild. You will need to pay the core deposit to start work. Check-ins are by phone; the shop does not emphasize walk-in inspections since most customers drop vehicles or engines off and return later.

Hours, parking, and logistics

405 Engines & More operates Monday through Friday, 8 a.m. to 5 p.m.; closed weekends and major holidays (verify holiday hours by phone). The shop is located in a light industrial area with street parking and a small lot. Bring your vehicle or engine during business hours for drop-off. Rebuilds are ready for pickup during operating hours or can sometimes be arranged for early morning or after-hours by request.

405 Engines & More fills a genuine gap in Oklahoma City's auto repair ecosystem by handling the engine work that most shops cannot or will not do, making it essential for anyone serious about rebuild over replacement.
