Plug Gapping on a Lump series 1 chevy 350
 

Hello all,

Once again I come to the wise men for advise on my 73 conversion. I am replacing the spark plugs but have no idea what to gap them to.(OR if I should gap them at all) I know there are some things that matter, i.e. compression, etc. So I will give you what I know. If you could tell me what you think the gap should be, I would be grateful!

Chevy 350 bored .60 over
9.6-1 compression
last used autolite #26 spark plugs
pistons hypereutectic 4.060
Edlebrock 600 cfm carb
electric choke
performance HEI ignition and wires

You mentioned having HEI ignition, not points and coil.

0.045" gap is standard.

Thanks Mikey!!
