2.56 to a 3.42...... Questions

Long discussion and a lot of help on another thread talking about engine upgrades, tranny, & rear end choices for my '68 Lark 350-2. The result of which is looking at changing up from a 2.56 to a 3.42 .

I'll be getting this done at a shop but just have a few questions:

1) Will I have to change out my axle gears?

2) Would you change Oil Seals and bearings since everything is apart?

3) Any recommended sources for parts?

4) advice??

Thanks All!!

Any time you decide to change gears,or otherwise work on an original,unmolested rear,just do it right and replace all bearings & seals.Do a full rebuild.

 

Yeah that was my thought as well. It's apart so why not freshen everything. Just wanted to hear some validation I guess.

Thanks

 

Going to add a question ......

4) Would it be worth while to locate a set of F41 Bars and install them? Not planning on going crazy with the 350 but....... I see in my manual that these were stock for GS350 & GS400. Thoughts?

 

I say Yes, cheep insurance. The stock type stamped steel versions are better than nothing, and are cheeper than the tube type.

Some reading on the F41 bars:

Thanks for the link to the thread! Yeah I figured it would be better than nothing. Any extra help transferring torque to the body I guess is a good thing. Think I have a line on a set. One of the cheaper buys for the upgrades I want! LOL

THANKS again!

Thanks Larry! That had slipped my mind.
