340 or 360?

I can put a set of Icon or DSS racing .080 over pistons in that camper van engine at zero deck with some good heads and it will run at least as good as a 391 mopar stroker with the same parts. All without the Stroker crank. That same 360 camper van engine is a 340 in disguise with a stronger block waiting for someone to bring it out. If it has the premium CD or BH casting truck crank, the crankshaft is as good as a forging. And I actually love a 340. Some of the quickest cars I have been in have been 340 powered. But for the $$$ and what’s available to me, it will be an early 360 for the win.

What's the purpose of boring it 0.080"? Wouldn't that cause over heating issues? I believe in only boring a engine enough to clean up the bores. There's article's on people running 1.925" intake valve's and port work that give just as good or better flow numbers than people who use 2.020" intake valve's. Attention to bowl area is important.
