Intake Elbow and Throttlebody
What is a good size elbow and TB to have on a stock bottom ended motor with......
ported NPI heads, PI cams, NPI intake.....
OR
NPI motor with PI swap.....
Looking into parts for my future SOHC build...the motor itself is staying pretty basic bc it will eventually end up becoming a 32V down the road. I know what works with with what on the 5.0 but the 4.6 is a new game for me.

All the aftermarket elbows are one size. Some will say a 70mm TB is all you need and some will say go bigger. If you're planning a DOHC future for this car then I'd say get whichever one you can find used at the cheapest price. But personally I lean towards the 75mm side of the fence...

Yea I just noticed that all the ones I seen were 75MM and the BBK was a 78MM elbow....
If I buy new I will probably go with the professional products 75MM TB and elbow from latemodel for $90 bucks...
