i'll take a closer look at the bottom end again harvey for you, nothing jumped out at me to be honest, but perhaps it should do?
if the crank is stock, it will be balanced already by Alfa to their tolerances, and i can't see any gain to be had from that being redone unless you were going to be asking more revs from it, and by that i mean if you were going crank mods, steel rods, and maybe higher comp etc etc
don't forget i've got the flywheel under the knife already, just about there now actually.
i havent touched the gearbox yet Harvey, is that supposed to be a 1200 box or something? trick diff perhaps?
back to engine painting, if you doing so much of it in a block colour, i think you'd be better painting it once reassembled personally, but what i plan to do already is help with the smaller parts and ancilliaries, which can now media blast for you given the time, so things such as the pulleys and castings etc will look new, and be ready to accept the colour of your choice very easily too.
as for myself or BLS suggesting things mate, i can spend someone elses money really fast, but it might not be wisely! ha ha!!
i think i would probably go with the simplest gains first, so seeing as you've got the fast road cams in, why not consider a set of JE pistons and rings and go up to 1.8 on the block, or use a 16v block to do it so that you have the under piston oil cooling aswell which is nice?
then maybe consider crank and rod improvements, but i think for a fast road car, that'll be far enough for me, and big enough to know what you've spent your money on.
after that the gains become smaller, harder and more expensive to find, to much more difficult to justify.
finally, once your up and running again, don't forget you'll be having a ripping exhaust system to breathe through, so finish the whole thing off with a dyno session with a really tastey carb guy, and you should be onto a winner mate!
