A different Q on 340 Vs 416

Like you said both should be equally fast.
The 416 would be a better street engine.
340 probably a little more fun on the track.

416 has less down sides. Unless you like a radical small block while idling at lights.
That’s kind of how I see it.

Personally I go 340 3.31, or maybe 3.58 or 3.79 stroke.
Wht! This again? Make up your mind! LMAO
I’m eye balling a 3.58 stroke for a 340 block I have hanging around, pending sonic checking.
