What trans do you have? I don't recall if I saw it but then I didn't go back through the info. 336's are good street gear. I moved up from 308 to 336's with my 325hp 350 with th400= little rpm difference in that jump. You will feel it more going from 273 to 336. If automatic it won't be a problem, with M20 Muncie or ST10 it will be good, if you should have a M21 CR it won't be too good. 5 Speed will be good although OD gear may be low.
Still Running the factory 4 speed. It's a Borg Warner Super T10 from what I can tell. I guess this it the ST10 from above.
