Heads and cam swap

If you get a good running 360 mag with under a 150k for miles, I wouldn't even do bearings/rings. These will push 300,000 miles without batting an eye.
They have around 245 hp (NET) hp from the factory, which would be about 300 gross. You'd get this with just a 4bbl.

  • Heads are a nice upgrade
  • Your 4bbl will add some top end power, as the keg intakes choke out the rpm's
  • In a 4wd, you may only want to upgrade the heads. You may like the cam as it has good low end torque.
  • You are correct with the manifolds, some have bigger outlets. A good dual exhaust ran off of those will aid in power too.
  • Good Luck :)

I will need to change the oil pan, so I could at least pull a few bearing caps and look..... Also, I assume a new timing chain, should be installed...... And would at least like to replace seals and gaskets before putting it in the truck. My plans are, if possible, keep it stock for now, and latter do the heads cam upgrade.
And thanks for your help!!
