Restoring a 340 need advice

First off... Noticed you joined today .Welcome to FABO!!

Lots of great info and good people on here!

My input.. Get the valve seats hardened for unleaded fuel while the heads are off. Cheap insurance and not costly to do. Keep the LD-340 intake, one of the best Mopar intakes ever made. I agree with the above posts, Keep the factory valvetrain. Cam choice will depend on converter /rear end gears/tire size as was stated previously. Headers will work wonders!

Keep us posted on your progress!!
