score! but i need help

If it were me, I wouldnt touch the 318, other than adding the parts that will interchange with the 360 later..Like the intkae, carb, headers, and ignition. Ignition is VERY important..Remember I said you eally need to read up on things..This is what I'm talking about. The 360 is the better choice..The longer stroke is worth much more on a street car than the .04" of pistons size. Plus, the 360 doesnt demand the same money. I'd grab Mark's engine, and give it to a reputable shop. You can and will do more damage than good if you just jump in with a grinder and go to town. Oh, and there are no templates for Edelbrock heads..Only good for factory iron heads.
