Engine Rebuilding

Rebuilt engine

We have been rebuilding Jaguar engines for over 40 years. We replace the bearings, timing chains, pistons, valves, valve springs and other parts as needed. 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 price and some cost extra.

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.)
