340 x-block vs. 410 stroker ?

This just isn't true.
And that is your opinion.

If jpar can't pull on you....then it must be running on 5 cylinders.
You gear that 340 for a reason...
410 cid's are pumping over 450 lbs on a bad day.
If this is a W headed, not w2's, 340 in a real race car....then aren't even talking about the same thing.
