350 HEI Identification

The engine in my truck is a 73-74 350 with an HEI that was probably added later.. I need a new vacuum advance for it but the parts guy wants to know what the distributor is from.. how can I ID it?

 

the first vacuum advance i would look at would be from the exact same truck you have except use 1975

 

Oh, I should add that the truck is a '46, so the engine isn't necessarily a truck engine. Is there any way to id the distributor on it's own?

 

The difference in the vacuum cans is the amount of advance and when they activate. Buy an aftermarket adjustable one from Summit. They all interchange physically

 

On the skirt of the aluminum base a GM p/n usually starts with 111 ...also check the advance weights for wear on the pins

 

ok, looks like 1105246 DL 1

 

That D should be a number, which would be the last digit of the year it was made. L 1 would be December 1st.

Didn't see that dist number in the Std Ign catalog.

I second the adjustable unit suggestion...

 

sounds good, thanks for the help guys!

 

checked again.. 1103246 6L 1? I need gl***es!

 

looks like a 77 car

 

Sounds good
