I tell you what, it really depends on a bunch of stuff; like'
application,application,and mostly,application,
But also on application,and application,
If you fail to take into account,application,application,
Then in your application, application, may not be a good fit.
Also if your engine is tired or worn out or just never made much low-rpm torque, then any guess is a guess.
Plus if yo have 3.91s or some other HO rear gear, you can get away with less TC..... or vice versa' if
you have hiway gears, the tired 340 might want a lil more TC.
But if your 340 is an animal at low rpm then the TC will depend on other factors, mostly like.....application,and application.
