427/390 similarities

Post by 69Highboy »

I was visiting a friend and chatting about my highboy when he mentioned he had a 427 block, ford cast headers, a twin carb intake manifold, a 390 crank, and to summarize he said all I'd need to source if I got it was a camshaft? and pistons. Would a 360 or 390 camshaft and pistons work in it? I have all of a decent factory 390, most of a 360 (at least that's what the po called it), and another 200,000+ miles 390 that may need to be retired (which is why I'm asking) to use as parts for the 427 (if I need to get it). So, could I source the missing parts from the engines I have?

I'm pretty sure the 427 has a larger bore than a 390 so, no, the pistons wouldn't work.

Does the 427 have heads with it?
