Standard V8 mill would have been the 2bbl 318, optional 340 which i think is overrated IMHO. 340 is same as a 318 in all aspects as far as crank rods etc. Except one. The 340 has a 4.00" diameter bore compared to the 318 having a 3.910" bore. You got a better dealio with the 360. 4.00" bore same rods as a 318/340, however it has a 3.58" stroke compared to the 318/340 3.31" stroke.
For a future build you may concider wanting t punch it out to a bigger bore, add a 4.00" stroke crank and build a 408/410 inch stroker.
Nice project car though. Lots of good advice, and information on her. Lots of good folks willing to help too. Your pic of the end result you want is freakin cool. I love the gray.
A piece of advice, dump that edelbrock foam element air cleaner. One backfire pop and it will melt and fall into your engine.
