I currently have a LO3 all stock and im getting ready to do a carb intake cam and possible heads swap. To go to carb do i need a different distributor?

 

yes, you will need a non computer controlled distributor

the easiest way to go would be to use the older style hei distributers that dont require a computer

 

Go here for an EFI to Carb swap:

This is the route I will be going if my 454 TBI will not work with the Vortec 350.

 

The page that 86z/92rs is the same one I used. It worked really good. Just have to splice into 2 wires. Its fairly easy.

 

Jeff, you wouldnt happen to have a spare distributor would ya?

 

Ill check and see. I got the stock one, but it want work. May have one.

 

i would look into the Mallory direct replaecent HEI units. They cost about $160.00 are billet and come with all the advance weights you'll ever need. I had my old HEI recurved and rebushed. I like it, but I went back to the Mallory.
