Open flame. Ohh, god, thats funny. 0.60. oh jees.

If you didn't notice. You forgot a 0

Back on topic, 0.060 for me too for pre series I n/a

CHUCK!!!! I think we all know Chuck means .060, although being a mechanic .... if he tells me he gapped a plug (ever)..I'm calling 95% of all the plugs he puts in are pregapped for stock application and have the gap protecting cardboard or plastic sleeve on them.

My gap is .045 but I don't recommend it for you

N/A should always be .060 (unless running nitrous)

Boosted 3800s should reduce the gap slightly (rouglhly .001 for each extra lb) with each extra lb of boost. 3.8 to 3.4 pulley is about 4 extra lb of boost so .060 should become .055-.056 (.055 is easier to measure for most so thats what we recommend).

Can I ask a silly question? How can you tell the difference between an L36, and an L67 engine?

Is one */C or is it the production years maybe?

L36 Series II N/A
L67 Series I or Seris II Supercharged
L26 Series III N/A
L32 Series III Supercharged

Thanks Rogue.

I'm running .057" on the 605 autolites and plan on throwing in the 104'* at .052" when i put my 3.4" pulley on.

lol yes the size is.060, the stock plugs i do put in are pre gaped for my pleasure. but i allways recheck the gap to all and any engines i work on. nice improve members.

I am now running the 104s on a .052 gap. Seem to work well. Haven't really tuned it yet. Coming next week end.
