Hi, Just to add a few more observations regarding past attempts to enlarge the Bristol 6 cylinder engines by the likes of Bob Gerards , Jack Brabham Mike Hawthorn ETC.

My suggestion that a modern engine and cylinder head built to almost exact Bristol original specs.needs some clarification,When i suggested that the "New"2010 engines dimensions be altered a little i was well aware of the limitations that existed in the say 50s even 60s ,and those were no modern synthetic oils no computer aided design .less empirical knowledge ,This list could go on and on.

One other area that has improved dramatically is the balancing of engine components by computer aided machinery. Some of the engine designers of the 40s50s60s era were incredibly clever futuristic engineers who in my opinion were at least 50 years ahead of their time, imagine what they could do with all the modern computer help/metallurgy that is now available.

The engine i visualise if it ever happens would be externally identical to the present engine and would be available in more than one capacity,the customer could choose standard bore and stroke at one price and bigger bore or stroke at another price.

There are endless examples of engines that have been made " big bore" and it was thought that the limit was found, using a Ford crossflow as an example at 1760 CC Only to discover later that someone managed to make them 1970 ccs.And who would have thought a 3500cc Rover V8 would eventually be more than 5 litres.
