I have heard the 3 main bearing engines don't last as long. No real reason to
remove the head. Seems it might be simple to remove the pan and caps and
check and replace bearings and cheap. >>
I actually prefer the 3 main as it produces a tad more power and revs a bit
easier. I have one in my 62 MGA Deluxe coupe and use another one in my TVR
race car.
I'd pull the pan and clean it up, and remove the centre main cap to see how
the main bearings are doing - problems usually show there before they will at
the end mains. If it is OK, zip it up again.
I helped a guy run a 7 hour enduro with a 3 main fairly highly tuned engine -
no bearing problems. I wouldn't worry about the engine being 'weaker'.
