Need cam help for 340 Duster

If the heads aren't off or look in the spark plug hole, to see what you have for pistons. Pop ups will make street driving difficult. Once you know the baseline you are working with, you can make a good decision about parts choice direction.

5.13's... they didn't twist it too hard. LOL I hope you are changing that out.

You have a good pic of the broadcast sheet. Always interested in 340 car info.
