Thanks Tech Ya your rite thats definetly a lot cheaper and pretty much bolt on to with no clearancing issues like with the 4 1/2 or 4 3/8 stroke.

I left out some info also. I have solid roller comp cam with .622 lift 110 lobe and 238/246 duration at .050. My heads are iron gm heads ported and polished 106cc with stainless manley valves oval port. I was wanting to go with the 4.5 stroke for more torque along with my oval port heads and longer rods for less wear on the cylinders and longer life.
