Hi Geoff
I have a 2.1Litre engine in my '67 Roadster which was built for me by Crankshaft Rebuilders, Melbourne, about 8 years ago.
I have since covered about 15000 miles of mainly longer distance driving.
My previous car (MGA) had a 1950cc engine and I am able to offer a direct comparison between the two large bore and the standard motor - there is none!
The 2.1L engine has been completely trouble free with virtually no oil usage between services (every 3000miles) and can return in excess of 30mpg in overdrive top at 60-70mph.
In our summers I often see water temperatures in the 90-100degrees range when climbing hills or in traffic but it then settles back to 82-85degrees under normal conditions.
There is abundant torque from very low revs right thru the range and it will safely rev all day at 5000+rpm.
I have 1 1/2" SUs (probably should have 1 3/4") with Performance pointless ignition, large core aluminium radiator, Wade 240 (Stage 2) cam, 9:1 CR, Holden 308 valves, thermo fan etc.
