I have 2" under chassis headers in my 67 dart with 383 and can do all 8 plugs in 30 min

That's pretty damn good!

I can do all mine in about 10 except #7. It takes a bit longer and scratching paint is always the issue, gotta be carefull with that one! Booster makes it harder.

# 6 comes out from under but easy!
