F-134 Timing

I replaced my 5-38 rear end with a 4-11 because I discovered my front end was a 4-11. I discovered this when I put it in 4 wheel drive. I have gained alot of top speed; however, it doesn't have the torque it used too. Would it help to play with the timing a bit ??? or is it just the nature of the 4-11 gears???

 

if the 134 don't have OD you prob wont see any difference by advancing timing these ole engs aren't ment for speed and by raising gear ratio to 411 will add a little strain on the eng you may want to consider maybe a size or 2 bigger tire if it will fit
I myself would have found a front 538
I have 538 in my 3b 4.3 sm465 dana 18 and love the gearing on trails

so I miss worded its fixed now

 

I also think 4.10's will be way to tall for a F head. You might get by with them paired with a set of terralow 3.15:1 gears in the D18 (what I am running with a far larger engine), but it would be marginal at best. Just plain not enough low end torque to make it work.

 

O.K. thanks guys....I am running 31 x 10 x 15 Pro- Comps.....Was sorta stuck cuz I spent all the $ to rebuild the front end then discovered the ratio difference alot later, It does pull great in 4wd low though.....
