Since turbos like load
What would be a better Starting Line Ratio?

rear gear 3.23 or 3.55
275 et pro tire on 10" rim

Trans
A-999
A-500

727
518

trying to decide which Trans/rear gear comb to run
street cruiser/ weekend track car

engine is .040 over 340,
9.64 compression
ported edenbrock

Watching >>>>Dizuster<<< turbo kit post

Was thinking about this
While
prepping the floor/ trans cross member for a 518 with trans shield.
Only cause it needs the most clearance to fit.

thanks
