<DIV>just to add to the general misinformation, I modified a different british
car (TR6) with mild cam, lightened flywheel, decked the block, polished and
ported the head as well as shaved it, mild cam, electric fan, and a few other
goodies. also went from 2 carbs to 3 (it’s a 6 cylinder). running
close to 11:1 compression. also modified the suspension, tires (but not
the wheels) and the brakes. remember – more go power needs more stopping
power</DIV>
<DIV> </DIV>
<DIV>car has a somewhat lumpy idle, but other than that is a joy to drive on the
street or the occasional autocross. the wife complains about the bumpier
ride, but my son and I love it. would totally do it again.</DIV>
<DIV> </DIV>
<DIV>plan the upgrades from the getgo. redo the whole car in a consistent
manner and you will love it. do one part, and you will start buying parts
to do another part, etc</DIV>
<DIV> </DIV>
<DIV>also remember this adage – if you plan on redoing a house, car, boat, etc.,
go out and get three estimates. then add them all up and that is what it
will cost you.</DIV>

add to these replies, which I agree with, it does depend on how you want to use
the car. I faced a similar scenario with my 72B’s rebuild about ten years ago.
Although it is an 18V engine block, I went with HC +0.060 pistons that I
acquired from the UK (ebay dealer mechspec who also has an Internet site). This
put the compression ratio around 9:1. I also used a 270 cam. I did not modify
the head except to have hardened seats installed. I was looking for increased
performance while maintaining the car as a driver. I was hesitant to increase
the compression ratio too much as that would make it harder to find fuel for it,
particularly in rural areas. This was based on previous experience – with my
first MGB, a 1965 B, I installed an engine with a 10:1 compression (as I recall
but it could have been higher, this was several decades ago). It was a fast car
but back then, when leaded fuel was still available, I sometimes had problems
finding a high enough octane fuel and in those cases, the car would keep running
after I turned the ignition off. I don’t recall the octane back then but where I
live now, the highest octane rating I can find locally (within a 30 mile or so
radius) is 93 at two stations, 91-92 is typical for the
rest.<o:p></o:p></SPAN></P>

<P class=MsoNormal>Hi Jack, et al.,<o:p></o:p></P>
<DIV>
<P class=MsoNormal><o:p></o:p> </P></DIV>
<DIV>
<P class=MsoNormal>Thought I would chime in, philosophically.

<DIV>
<P class=MsoNormal>Just please remember that any engine design is a tradeoff
between power, reliability, and cleanliness. Add to that known adage,
'drivability'. Old engines have fixed cam timing. That means the valve timing is
set to the give optimum drivability - so maximum top end performance is not
achieved. But if you tune for 5000rpm, the car is beast to drive at lower
speeds.<o:p></o:p></P></DIV>

<DIV>
<P class=MsoNormal>Okay, I've said what everyone else has said, perhaps except
for this: What is YOUR goal? Decide upon that then build accordingly, and accept
the limitations associated with that solution.<o:p></o:p></P></DIV>
