The cool thing is that you don't have to deal with a "30 year old motor".
One of the things that have always impressed me is the quality of the
blocks in these cars. I don't think I've ever pulled the head on one (at
least the L-4s) and found a ridge. If the block's good, new rings,
bearings (if needed) and a valve job can make a big difference in how
hard you can safely push it. You'll definitely want fresh valve springs
to push 7K. This doesn't have to cost an arm and a leg either. There are
bound to be alternative sources for valve springs if the dealer price is
too steep.
While this may seem contradictory to what I said about building a blown
U-20, I don't think it is. We're talking about trwo completely seperate
directions, one freshening a basically stock motor, the other looking for
a lot more power.
FWIW,
