Re: carb work

If it's the standard old motorcraft 2v. the only tuning screws are the idle rpm and the air/fuel mixture idle screws.
You notice and performce gain by adjusting either of these.
But if the truck is running ruff you may be able to smooth out the adle w/ these.
Hope this helps.

Re: carb work

You can really wake up the M series motors with a pre 73 351c timming set. They had a 13degree retard from the factory for emmisions(on the M motors) fixing this is good for at least 30hp! Ad an edelbrock performer intake and 600cfm edelbrock carb with the timming set and really wake it up!
