I'm considering notching out a piece of this panel and bending it out to funnel some air to this area. Just thought I'd add my own observation!
I suppose that is why they started to add the vents at the wheel well around 85/86

GMC 454 Manifolds

I have a 1989 GMC 3500 dually that is on it's 4th set of exhaust manifolds.
I also have a 2005 Chevy 2500 HD that is on it's 2nd set of exhaust manifolds.
The 454 bolts could all be removed without breaking but the Chevy has a reputation of bolts breaking and exactly half had to be drilled out.
Happy Camping nm1oqrz

When i did mine i drilled the mounting holes out to. 437 and used grade 8 12 point bolts with hardened tooling washers and thick copper gaskets ----no problems since in 8 years. When i go to headers ill cut the flanges between the pipes for a little compliance --- works well on the test stand engines at work.

Very good indeed. I tell people that there are some very good deals on these older classics but if you can't do the work yourself, they will eat you alive!

If my frig ever fails, it will be replaced with a conventional and inverter.
