400 cubic inch Pontiac buildup: Part 4


  The Pontiac engine buildup resumed once a replacement timing chain was procured. I was lazy and installed the cam "straight up" without degreeing it. I installed the fuel pump eccentric and torqued the bolt with threadlocker.
  I next installed the valvetrain. The pushrods and roller rockers are from Comp Cams. Posi-locks are used to keep the valves adjusted. This is a real basic build and the roller rockers are the only real "trick" pieces on the engine.
  With the valves adjusted I installed valley pan,valve covers and intake manifold. The intake is a vintage Edelbrock P4B (pontiac four barrel) it was kinda grungy so I painted it Dupli color aluminum blast paint. The Valve covers are Moroso anodized gold held in place by the wing nut valve cover bolts.Most of these parts are to give off the vintage 70's vibe.
 Here is the finished product with the front cover and water pump installed and the Hooker super comp headers. The ignition will probably be a HEI although I would like to use a Pertronix ignitor kit so I can use the old points distributor. Once I get the transmission squared away It'll be time for installation and startup......I can't wait
