Need 318 Gurus

Matched as a set:
Red =

• Dampener,
  
• The bolt on "Timing Mark" bracket
  
• Timing chain cover
  
• Iron Water pump
• Both Crank and fan pulleys.

You can move these over to the Blue engine as a set.

Oil pans... Yes you will need a truck pan for a 318. Use a LOW volume oil pump.
But for $260 get a Kevco 318 truck pan and matching $60 Kevco pickup. This gives so much better oil control and with its scraper and baffels frees up 10 to 15 HP at 4500 RPM.
