Technical Delco points distributor choices??

I’m replacing the stock GM HEI distributor in the ‘63 283 that’s going in my 40, mainly for the early look and the firewall clearance.
I have two stock, single point, alum body distributors to choose from.
MSD or other after markets are not in the budget right now.
Street driven, stock 2 bbl engine for now.
Probably go to PowerPak heads and small 4 bbl after some miles.

Will one offer any positive benefit over the other?
Definitely different advance weights. Don’t have advance info or access to a machine.

ID’s are from a Chevelle site.

Thanks!

# 1111152 - ‘66 327/275 HP
# 1112002 - ‘70 350/250 HP

 

With out curves to each (70's being already smog era) and a wild guess on my part I'd use the 1111153. But why would a '63 unit be aluminum?

 

The 1111153 comes up 1966 cast iron with tach drive.

 

I'd think that you would want to go back to a 57/58 style distributor. Similar to this one

My bad on the numbers, @Johnny Gee . Cold meds have me off the bubble today. Corrected.
1152 and ‘66 327

 

Please educate me, I’m getting ready to small block my 1950 3100, other than material, what is the difference between cast iron and aluminum distributors?

 

Thanks for the tip. That’s probably a good price, and a nice piece for sure.
I do like the later cap with the window for point’s adjustment, though.

 

Hmmm, and I was sad I paid $40 for 4 distributors.

Some say the cast last longer bushing wise.....besides looking older. The spring rate can be set up later unless you decode a super rare one. I would run either one.....whatever you can find in the best shape (that goes for cast iron vs aluminum also).

 

I have tried all types of distributor, MSD, Accel, HEI, dual points...I have always come back to
stock GM single point distributors. You can play with the weight springs to have the advance come
in sooner, or later, plus different vacuum canisters plus adjustable ones. Keep in mind that the
Z28's and 409"s ran single point GM's with no issues. I have spun them to 8k with no float or
failures. I also like the window cap to adjust the points while running. Look on the web for
spring kits, typically 3 pairs in a pack, dark, silver and goldtone.

 

I've been collecting nos points and condensers, plus these:

 

I happen to have a clean cast iron unit that has not been run since a fresh hot rod curve, IIRC codes to a 1965 Corvette, 327 auto
