What a performance nightmare with that air cleaner! Let's suck in the hottest air possible into that engine and see what our performance looks like. And then not plumb in the breather so oil vapor sprays all over all that shiny new engine! Tranny dipstick is broke too.
Yup..definitely needs a cold air dual-snorkel set up. When I had my '72 Dodge B200 I retrofitted a trans dipstick from an '80's van so I could check the fluid without pulling the doghouse.
