440 power gains/ aluminum head advantages?

I'm not speaking specifically to any of your questions but it'll speak to them all. Very unusual but wonderful to see someone young whom is pretty deeply engaged in building a hotrod. Pull and sell the dinosaur driveline and put a junkyard Eagle gen3 in it and watch your efforts pay off in larger dividends. You'll go a lot faster for less money and it'll be more reliable. People who know me wouldn't believe I'm recommending this but, in the context of everything I've read here, it's sound advice.
that's initially what i wanted to do when my 318 gave up but this is my first real in depth build outside of just re ringing engines and replacing parts with factory equipment so i was weary with a new gen swap. but i've got an 88s10 and a 5.3ls3 that's on the chopping block at some point after my 68 torino gt is done and i do something with my 66 d100. there's also this 73 challenger that brad harm in viborg SD has sitting with his hundereds of other mopars that i've really been eyeing. hoping to grab that up before he sells it because i'd love to restore an E body. but there's only so much time in each day. not sure if posting F.O.R.Ds is allowed on this forum ha but i'll include a picture of what my torino looked like the day i took it home after i got done painting it. it was pretty rusty but not a spot of rust left after i put 1/4s, torque boxes, wheel houses, trunk extensions, rocker panels, and lots of other little fab pieces where it needed it.
