Engine Rebuilding

We are working on revising and updating our website. Check back soon to see the changes.

Rebuilt engine

We restore your engine inside and out. We replace all bearings, timing chains, pistons, rings, valves, valve springs, cam bearings, chain guides and tesioners. We replace other parts such as valve guides and tappets as needed. We adjust the valves and balance all rotating parts. Everything is cleaned, detailed, plated, polished or painted as appropriate. If it needs to be done, we do it. We use the best quality parts available and our machine work is exacting. We offer performance enhancements and updates. Some are included in the base price and some cost extra. We also recommend that the water pump be overhauled or replaced.

Please check out our Shipping page for more information about crating and sending your engine or cylinder head to us.

*The base rebuild price covers engines that don't need excessive cleaning or have excessive damage. If your engine is excessively corroded or rusty or has a stuck piston or other problem, we will call you to discuss the extra charges.

3.8 Blocks require sleeve replacement during the rebuild process so that the cooling slots can be cleaned out which is why their base price is higher.

Special Flywheels

We offer a super-light steel flywheel for the XK engines. It comes in at around 16 pounds with dust slots and Swiss-cheese lightning holes. It will run cooler than stock and give a better grip surface for the stock-style clutch because of the dust slots which not only move the clutch dust away but also pump a small amount of cooling air. We also offer an aluminum, steel-faced flywheel for the XJ-40 3.6 and 4.0 engine. Inquire for V-8 engines.

Con Rod Matched Set

We provide a matched set of connecting rods appropriate for your engine. (The connecting rods used in an XK 120 will fit in an XJ6 but they are a lot lighter and weaker than an XJ6 connecting rod and not appropriate.)
