balancing. / Shot peening my rods?
Ok so if a grind them smooth (the sides of my rods) i dont really need to
shot peen? Hmmm maybe a wont bother anyway then. Just figured lighter rods
are easier on everything as well.

I wouldn't bother with shot peening unless you plan on making more than
300hp.

Yeah i just have stock pistion (1mm overbore though), ARP head studes,
ARP
conrod bolts. Crank, is shaved done .25MM. I was thinking of grinding
the
rods a little bit like they show in the performance VW book. Then you
need
to shot peen it. I was just wondering if i can shot peen with me
sandblaster
cabinet. Do i need too just buy shot peen pellets? If so where can i
find
them. I tried princess auto but they didnt carry anything like that. Any
ideas anyone?
