Well the diff. between the 1350 and 1410 is the same as the diff. between the 1310 and 1330, with that said, back when my pickup was all 78 F150, i broke more 1310s than 1330s, so i upgraded to 1330s with parts i had layin around. they seemed to hold up better than the 1310s.. So with that info i would figure the 1410s are a bit stronger than the 1350s. If i start braking my 1330s in the front Dshaft i will upgrade to 1410s, one reason being i think they are a tad stronger than 1350s, and also i would only have to carry one size ujoint as a spare.

 

i think what helps make them stronger is being more angle capable.

a 1410 at 10* isnt under as much stress as a 1350 at 10*

 

To the OP, if you plan on running long tube headers on your truck, you will run into the nasty problem of the front driveshaft and header wanting to take up the same space with a 205 installed.


It's an old pic from back when my truck still had a TTB, but you can see how close the driveshaft is to the header with a 1345, move the output 4" towards the center line of the truck and you'd have serious issues.

 

my 205 will be about 8" farther back, which should help slightly, but most headers that I've seen will say "not for solid front axle" or "not for Dana 60 front axle". I'd prolly be looking for some 79' or older style headers to work with the 205 and D60 front.

 

The headers installed in that picture have that warning, and they fit just fine with my 60.... I might go grab a picture from the same angle tomorrow.
I may be putting a 205 in my truck, but, I plan on working around that issue with a 1356 doubler and a 2 piece front shaft....
