Exhaust Manifolds Q'sexaust manifold paint,whats every one using?
just curious what every one is using for a natural cast finish on their exhaust manifolds.thanks in advance
I used Eastwood's brush on manifold paint. FOLLOW THE DIRECTIONS! It does work better that way! Also, I had mine media blasted clean before painting them!
Well i used POR 15 exhaust paint in 1998 on a car i rarely drive. The manifolds were beaded perfectly clean and painted and heated up by running it. I just noticed yesterday some tiny rust spots on the one side. Needless to say I am pissed since the car is kept in a dry garage and barely driven...so I guess I'll haveta touch it up
My manifolds are holding up very well with the Eastwood stuff.
I use the Martin Seynour Cast Blast, the 1400 degree one. It comes in a spray can.
I used a 1200+ degree high heat paint from Car-Quest and it really does a great job of sticking, cant rmember the brand right now, but will check in a bit. I thought it would burn off, but it didnt and I'm happy!
I use the Eastwood stuff too.The way I do it is to get the manifolds sandblasted right before startup on a new motor and brush the stuff on.The heat will cure them pretty quick,but it stinks to high heaven! I put it on the manifolds in my conv 3 years ago,and it looks as good right now as it did when I put it on!Good luck
I used the POR and it has held up great on my Demon even on two 400 mile road trips.
Ditto on the Eastwood manifold paint and sandblasting. Mines been on for four years
Who makes the high heat manifold paint for year one? It has a higher temperature rating than the eastwood paint. I have used the year one stuff and it has held up real good. I blasted the manifolds first, then cleaned them with dupont triple etch and brush painted them.
70 B Body - 440 Exhaust Mainfold Options
I put a set of MP Aluminum valve covers on my 70 GTX. The look great, but, the one on the passengers side touches the exhaust manifold. I really don't want to put headers on my car if possible. Is there another exhaust manifold for the right side that will not touch the valve cover? I have a complete 440 out of a 73 New Yorker, wonder if that one will work? Anybody got a fix?
Before I put headers on mine I had the cast manifolds with MP aluminum valve covers. The right(passenger) side casting number manifold was a 2806900. It didn't touch the valve cover. You could put double gaskets on the manifold to shim it out a bit.
Thanks, I'll check mine tonight. What headers did you use just in case I go that way?
can you remove a little metal from the valve cover where they make contact. I wouldn't want to use that 73 c-body manifold. It will be more restrictive plus your head pipe won't match up.
Mine did the same thing with the stock exhaust manifolds on a 1970 440-6 Pack. The new MPs are sitting on the shelf and I am using stock.
