Modified L31 with a Proflow 4 system

I like those heat shields too. Did they come with the manifolds or are they custom?

They are L31 350 manifold shields. Still available new from GM for about $5 ea. The dipstick and tube are also for a L31 truck or Tahoe. I looked up many of the part numbers on Nemiga parts.

The one thing I have not been able to find yet is a G-van 454 air duct. The 454 air cleaner and duct has an air inlet that is 2x the size of a stock small block.
