Taking my 68' 340 std bore block in to get sonic checked and see how the bores look this week and need to start ordering parts. This is going to be street/strip type build. I'm looking at a few different forged cranks. K1 heavy but cheaper, Scat and Callies which are lighter but more $$ Is 10-12 lbs savings worth the extra $$$ I plan on going with scat 4340 I beam rods.
