I pulled the old diff out. The centers sure look the same. Both spider gear carriers have a 3" opening. They have the same main casting number on the pumpkin. The clean/dry one is the new 3.55 geared one going in.
Looking at the service manual for the '64, it does state that the axle shafts are the same length between the sure-grip and non sure-grip differentials. I guess the only real way to find out for me is to stop reading and get it cracked open.
That's what I think I'm going to do, that way I can just go back to the 2.76 if I don't like the 3.55. I suspect I'll like the 'stoplight bandit' performance quality of the 3.55's.
The 3.55 complete pumpkin was free to me so I'd like to make that work....I could just take the ring and pinion from it and swap that in to mine I guess but that's gear setup work which I've never done. But, at least there isn't a crush washer to deal with. I'd like slightly lower gears but the...
Thanks, that's what I figured and experienced in the past with modern stuff.
That brings another question now....can I just cut the axles down 1/8" each to make up the 1/4" length difference?
I believe what is in it now is open gears, the tag on the diff is long gone....but with both wheels in the air, they spin in opposite directions. Any way to tell other than trying a burnout or the tag?
Can a complete 3rd member from a later year car be swapped into a 64 with no issue?
Would any adjustments need to be made?
Both centers are complete assemblies, open gears, stock is 2.76, other is 3.55. both cases are 741.
I didn't think about using hotter plugs. Why does the distributor need to be changed? I'll be using a hall effect points eliminator conversion kit in the distributor.
Thanks, my stock exhaust was a single. However it was basically non existent so I fabricated a 2.5" dual exhaust.
I have been searching around me for a local 383 4 barrel intake but have not had luck so far finding one. Everyone seems to be a Chevy guy around me ha.
On a 361 with a 4 barrel carb running an adapter on a 2 barrel stock cast iron manifold, would there be an appreciable power increase to switching to a 4 barrel aluminum intake manifold?
I got a free Holley 4 barrel carb from a co-worker but my 361 has the stock 2 barrel intake manifold. Would...
