Tuning help, please
Yes, Just like Woody said.
I looked in my 66 service manual and it has 3 different timing settings for 2bbl,4bbl,auto and manual.
2bbl manual shows 5* BTC .2bbl auto shows 10* before. Now get this,cars with cleaner air package ,2bbl manual or auto
its 5* ATC.
The 4 bbl auto or manual shows 10* BTC if it has the cleaner air package auto or manual its 5* BTC
