The Stovebolt Site Forums The Shop Area Engine Shop NEW - Fenton Header Upgrade Kit

Just got a note from Jim Carter advising that they have developed a manifold preheater setup that works around problems that many of us have had for a long time. Most try to use the coolant to pre-heat the intake but this uses exhaust gases to do it which to me makes a lot more sense.

Here's what I got in the mail:
Fenton Header Upgrade for GMC Engines (and you Chebby guys too!)

Interesting. Looks identical to the ones which some guy used to sell on the internet (e-bay). Maybe making them for Carter now. Only thing which concerned me about those was constant heat whether needed or not. Get the carb too hot in the summer? Would like to hear from anyone using them.

It sure looks like Stovebolt Engine's heater plate. Zeke

Yes, it is like the plate from Stovebolt (Tom Langdon). I have one. The plate on eBay was machined differently.

I use water with mine because it circulates throughout an Offenhauser intake and the intake will never get hotter than the coolant temperature.

It seems to me that by using exhaust air the heat transfers by diffusion and not by circulation. Don't know if that is good or bad or neutral. The hot-air hookup sure looks nicer and is easier than running hoses to the water pump and/or thermostat housing.

There was a comprehensive discussion on heated air vs coolant in this forum during this past year.

Humm, that looks a whole lot like the one I built myself, easy to do, works fine and cost a whole lot less then 48 bucks. The onle problem I had was getting clearence between the Fenton header and the offy intake. A little work with the grinder and it was done. I'd say build it your self and sove some money. Just my $0.02

46forme,

Did you heat with water or air?

Thanks, Tim

tcleaderman: I used air. Out here in sunny Ca it doesn't much matter. Back where it gets real cold water might work a little better better. Using the exhaust looks better IMHO.
