Default LS3 in 57 chevy

I am putting LS 3 DBW Connect & Cruise in 57 chevy. I am fitting parts right now & need to know if it is OK where to put map sensor .
Because of space I have to take the air tube on a 90 out of throttle body
and straight down & then on a 90 over to driver side fender were i will put air cleaner. Is it OK to put it in straight tube going straight down , will it work OK ?
I plan on using fresh air vent at headlight ,& cut hole in fender well to supply air to cleaner. Thanx Butch

The MAF can go there. I believe the MAP senses vacuum.

The wiring kit will include instructions on how GM wants the MAF positioned. If you meet those guidelines, you'll be fine.

Should not matter about level or not. The engine will suck air through the tube as needed. The only thing it will be fighting is gravity, and that wouldn't even be a measurable negligible effect.

Putting the MAF, [includes the IAT], in the fan wash, can/will create false intake air temp readings. The ECM will calculate whacky fueling/timing corrections..........
