I have a 41 Chevy with a 46 engine and its been running a bit rough so I've taken all the plugs out to look at and replace them.
The manual and Jim Carter site says they should be 10mm plugs but they are 14mm AC45 plugs - well 2 AC45 and 4 AC45s which won't be helping.
Anyway I plan to get AC46 plugs as the AC45 are a bit black so thought the hotter plugs would be better - but why do I have 14mm plugs in what should be a 10mm head?
Thanks in advance.
For those who believe, no proof is necessary. For those who don't believe, no proof is possible. 41 Chevy | | | | | Joined: Dec 2006 Posts: 1,464 Shop Shark | | Shop Shark Joined: Dec 2006 Posts: 1,464 | Someone probably slapped a later head on there sometime in the past (not unusual at all). Look at the casting number on the head and look on the Inliners site or post them here and someone can ID it for you. | | |
