May also drop in a Scat tater' sembly with a 4.375 stroke and .06 os pistons. This is an early block, (Mark IV)., and I may be able to bore .125 over. If so I will shift my bores toward the intake valve .02-.04, and the shift would be about 45 Deg toward the back of the block, and toward the intake. Helps unshroud the valves and is good for min 10 free HP. I will also deshroud the block on the intake side as well. This takes about .2 cc of compression away, but can be compensated for by gasket thickness. This is all $$$, so every essential thing that needs to be done on the truck will be done first, Engine will be the last. Would love a 572. Age and cancer may have made me a little crazy, but I was reading about a feller's dad and mom that scrimped and saved and denied themselves all there life, and then died. I have done the same, my kids got money, I will give them a bunch, but feel less frivolous about spending 10K on a motor I have wanted all my life, now 70 years. Seems my right leg is a litter weaker now, accelerator peddle sees the floor almost every time i get in.
