Price range: $5,788.08 through $8,810.07
-
Current build time: 4–5 months on most rebuilds. Times may vary based on parts availability and build queue — we’ll keep you updated throughout the process.
EMS EcoBoost Long Block Rebuild — you send us your engine, we tear it down, keep your cylinder head, and build you a fresh long block around it. Available in two configurations.
Budget Rebuild — built for up to roughly 550 WHP. Forged H-beam rods, MAHLE pistons, ARP CA625+ head studs, balance shaft delete. Cams and upgraded springs are optional add-ons. Despite the name, nothing here is stripped down — it’s the right parts combination for the power level, built to the same EMS machining and assembly standards as anything else we make.
BadAss Rebuild — built for roughly 700 WHP and up. Wiseco BoostLine I-beam rods, keyed rotating assembly with pinned OEM crankshaft, ARP CA625+ head studs, balance shaft delete. Cam and spring upgrades available for higher boost. The right choice if you’re planning aggressive boost, track use, or more power down the road.
Every rebuild includes: new EMS-spec block, keyed OEM crankshaft, King main and rod bearings, new oil pump, new oil squirters, new intake and exhaust valve seals, new OEM head gasket, and a new Ford OEM rear main seal. Your timing cover, oil pan, timing components, and oil pickup tube are inspected at teardown and reused if they’re in good shape — replacements are available in the options below.
Parts disposal: damaged, worn, or unusable parts removed during the rebuild are disposed of by EMS unless you request their return before the build starts.

HOW DOES AN EMS LONG BLOCK REBUILD WORK AND WHAT IS INCLUDED?
You transport your car or ship your old engine to us in East TN. When received at EMS, we will tear down your engine while keeping the cylinder head. Your timing cover, oil pan, timing components, and oil pickup tube will be inspected during tear down. If in good condition, they will be reused in the rebuild unless replacement options are purchased (available below). If your engine is blown, we recommend new timing/oil components in the drop downs. (Camshaft and springs /retainers upgrades are available in the dropdown menu below.) EMS will build a brand new block (or used if provided) using EMS spec standard comp or high comp Mahle pistons, keyed OEM crankshaft, Weisco Boostline Rods, King Main & Rod Bearings, balance shaft delete, new oil pump, and new oil squirters, and new intake and exhaust valve seals. EMS will then marry your freshly decked core OEM head to the new EMS block using EMS spec CA+ 625 head studs and an OEM head gasket. We will install the oil/timing components and covers provided with the core engine to the rebuilt engine and time it. Lastly, EMS will install a new Ford OEM Rear Main Seal. From here, EMS will either ship your engine to you or install it in your car. Shipping and Installation charges are not included.
Important Notice: Damaged Parts Disposal Policy: Any damaged, worn, or unusable parts removed during the rebuild process will be disposed of by Engineered Motorsport Solutions (EMS) unless the customer specifically requests their return prior to the start of the build.
