RE: 250° F - is that too hot?
Im going to try and make some baffles out of 1/4 balsa sheets for the front. It seems like it is plenty strong but I will use some light glass for added strength. I already have the bottom of my oil pan cut so I cant do the lip unless I glue an extra piece on the end. I also cut out the louver vents on the sides of the cowl not sure if it will help but it was pretty easy to do.
