It's really important that we know if it's 3-main or a 5-main motor.
I have just completed a rebuild of a 3-main for my MGB which will be
vintage raced later this year. This is also my summer daily driver,
so my main target was to get as much torque as I could find within the
constraints of reliability and drivability. I have been driving the
car for about 2 months now and it is definitely is freeing up - it
seems to rev more freely and hits 5500rpm real quick.
I achieved my goal (although I can not measure reliability yet), but
the engine has GOBS of torque, so much so that I can out drag my VW
GTI (8v) upto about 60MPH. Then aerodynamics and gear ratios start
playing a part and the MGB start to get left behind. Both cars weigh
about the same, so I figure I have about similar HP (about 105) to the
VW but much more torque (this is a seat of the pants feeling).
Personally I think your goal of 6800-7000 redline may be optimistic
(if you don't want to build a grenade), I would stay a bit more
conservative. If you build a solid bottom end, then you can go to
6800-7000 later on.
