I don't know which TB to choose 70-75 or 90mm, i will use a EFI victor jr, 205cc AFR heads and the engine will be an NA 408w stroked 351w, does anybody has any ideas?

85-90mm would be my choice...

my buddy runs an old 86mm throttle body that Ford Motorsport used to make on his NA fuel injected 408W......he also has a custom made inlet tube..using 4 inch piping and hes got a 80mm Pro-M mass air sensor

for a motor that size, and being NA...the more air u can stuff in there the better.....
