I have 2 areas between intake runners that are hot spots. So much so that it's burning the paint off between runners 1 and 2 and runners 7 and 8. Whats the bad news?
No bad news. The exhaust runs through the intake manifold on a 428 (and almost all FE engines) between runners 1 & 2, under the carb & runners 7 & 8 to warm the carb in winter. Some people (me included) block those ports on a restored engine so the paint doesn't burn in those spots & if you don't use the vehicle much in cold weather months. You can touch up the paint from time to time if they are not blocked.
Thanks, that's a relief. The car has had an alum intake for the last 45 years so I've never noticed it. Now trying to use the cast iron itake so i see hot spots. Wish I'd known to blank the ports when I swapped intakes. How is that done?
I cut a small piece of sheet metal, knock it in with a punch. Cover with epoxy.
I live in the deep south, exhaust crossovers are not very useful here.
That doesn't sound too difficult. Thanks Drew.
If you have spilled some fuel before that will accelerate the paint loss
