jet hot intake manifold???
anyone jet hot their factory cast iron intake manifold ? I was thinking of coating mine on my 71 bigblock, just for looks. do you think it would affect performance? if it stays cooler that would be a plus. they coat it inside and out.

i'll bet somebody has tried it; but something tells me that it's not the best solution. you could use a ceramic rattle can paint to the top, add a shield under the intake to keep the hot oil off, restrict or block the heat cross-over.
you can do a google type search on coating emissivities (they are more a function of the type of paint or coating than the color), and also add aircraft in the search. it turns out that the type paint in the engine bay has a very significant impact on the effectiveness of any coating on engine parts in an attempt to lower engine conponent temps . . . good luck!!!

anyone try it ? I had some factory exhaust manifolds done for a customer they turned out pretty nice. I would go with an aftermarket manifold but for a 71 454 with the original big block hood there are not many choices other than single plane manifolds

i used a high temp headder coating like jet hot on my team g. it came out quite nice. i have been told by others that have done it, that it holds up very well and does help with heat. here are some pics.

before i had it done i talked to several people that had it done to theirs. they all reported a slight gain or no noticeable change in perofrmance. the main reason i had it done is for show and for ease of cleaning. i seriously doubt it will have much affect on the performance of the engine either positve or negative to a point i will be able to tell.

i was doing a little research on this some time back and came across a report (on the net) published on this matter except the subject was small engine aircraft. as i recall, the coatings used on the firewall and inside cowling had a significant impact on engine temps such that ignoring this factor could negate any gains made with coatings used on the engine. might take a while to find the link if i even saved it - if anyone were interested . . .
