I had an '84 El Camino with a 350 small block, and I could get all 8 spark plugs changed in an hour. It had some Hooker headers on it, and those slowed me down a bit, but still, an hour.

no joke. i used to not need a swear jar for changing an air filter...

Yep, they used to put them right on top. Unscrew one wing nut, take off the lid, take out the air filter, blow the dead grasshoppers out of the pan, bang the air filter on the pavement, hold it up to the light, say "hey, it's good for a few more miles", put it back together. A 30 second job.

:iono:

even better, flip the lid, and let the motor roar!

my dad showed me that with his silverado when i was 8.

he also ran that silverado with a hole in the exhaust for 2 years because it sounded like glasspacks.

What size m40,m45 our the m50 plug?

I am running M50 which is one step colder. M40 is one step hotter, and M45 is oem heat.

I picked up the m40’s I guess they should be okay I’m running E85 and with the colder plug is everything running good?

M40 is hotter. I use one step colder plugs because I spend all my driving in the higher rpms. I need the extra protection benefit from the plug.
