Tuning and Modifying the Rover V8
The purpose of this text is to give some insight into the Rover V8 engine and how to rebuild with a view to optimising for better performance, reliability and economy. There’s some useful info at the end but I’ve deliberately left out the reams of measurements of bearings etc as it’s easy to reproduce it incorrectly and it can be found elsewhere quite quickly.
What if I want more power and don’t want to go and spend lots of money or time doing all the machining and stuff?
If your engine is in good condition generally, you could just change the camshaft. Its
worth a bit of extra torque and around 20bhp on a 3.5L or 3.9L V8. Tidying the heads
and matching the ports will give further gains and accurate ignition and fueling
with a free flowing exhaust will top it off. If you had an EFI system on there instead
of the carbs, you could reasonably expect a reliable 200bhp from a 3.5, probably
