as said earlier, have a driveshaft/clutch shop shorten the shaft and at that point put on the 1350 series yoke. If it were me, (and you can afford it) I would have the front changed also. No sense in having a small diameter, lighter duty u-joint in a heavy duty setup.
I'll stick a guage on it and drive it but, If I'm on the ported sie of the system wouldn't the vacuum be high through that port since the vacuum is created by the air flow through the venturi flowing past the port and creating the vacuum?

I understand the maniforld vacuum...
Interesting little experiment yesterday. I bumped the initial to 16* and disconnected the vac can. My total ran about 34* at 3000. Reset the idle and went for a drive. After everything was warmed up, I stood on it and under full load, I was getting backfire through the exhaust and black...
good point. here's a quick map:
Manifold vacuum 10-12 HG at idle
Timing:
1000 10*BTDC
1500 12
1750 19
2000 24
2250 28
2500 32
2750 42
3000 48

i also checked my vac can by hooking to manifold vac. timing went from 10* to 40*. So ~30*. Ya, if I...

Haven't mapped the curve.
At idle, none on the ported side.
Didn't check manifold vacuum.
What are you thinking as far as initial to try?

I'll go back out and hook up the test equip't and check.
ok, I dug up the cam card and double checked the timing.

anyone have an opinion on the "heavily cammed engine" and the ECHLIN dist. vac. adv. Mr. Hinckley talks about? Clearly a chebby PN. but does MoPar make one? Adjustable?
Right now I have that situation and am running off the ported vacuum side. I'll play with it this weekend.
Thanks!! They're all bias ply. This was taken when I had Hoosier 31x13.5-15 Quick-Time Pro's on the back and Goodrich 7.10-15's on the front. I now have Mickey Thompson 28x12.5-15 on the rear and it handles much better on the street with the stiffer sidewalls. I can fit 29x13-15's
