Big horsepower 318 builds

a 318 turning 7500 rpms needs more air than a 390 turning 5800,..id go ahead with them R/T's!!
If not for the moderate probability of me destroying the whole thing during the tuning process once turbocharged; I’d go that route now, but it runs good as is and I don’t want to go too crazy as it’s kinda ready for boost now-ish.
