Today's Car Engines are far more sophisticated with Double Overhead Cams / 4 x Valves per Cylinder / Variable valve timing / Fuel Injection / Computer Chips / Electronic Ignition ...etc
Try overhauling that sort of engine and see how much it will set you back.
An early Holden Motor can be overhauled many times for the cost of 1 overhaul on today's complicated engines and still cover 300,000KMS and be far far cheaper in overhaul cost.... although fuel cost would be higher ( non injection ).... some of us lads in the engine build up section at the Airbase completely stripped a Holden Red Motor and rebuilt it with all brand new parts ( head cylinder re face / valve lapping / a new Crane 25/65 Cam / all Bearings and gaskets / honing the piston bores / new chrome rings / spark plugs and fitted the engine out with Twin Carby's and elected to use the standard Exhaust Manifold.. ( no extractor's ) ....put it back in the HK Belmont with 3 on the tree
(Column Change ) , ...so we took it for a lengthy run and we got 28miles to the gallon
( 4.5 liters of fuel in today's terms )...exhaust pipe at the outlet was a nice grey colour indicating it was very well turned ,resulting in excellent fuel burn
That was a big deal in those days....the average 6 cylinder would do some where about 23 to 25 miles per gallon.
I grew up in the 60's ... things were simple then .... today it's more complicated then ever .
We certainly have come a long way ....!!
