I'm hoping to avoid re-inventing the wheel with my planning for a heat stove. I've been thinking I could make up a cardboard pattern by cutting and fitting and building a device that will capture some heat from my Dutra "Dual Dual" exhaust manifolds and directing it up to the Offy intake manifold. Has anyone here done that sort of project? Or is there an easier way (like someone already building such a device for sale)?

I've seen water heated intake manifolds, but the ones I've seen do not have much eye appeal to me.

Any ideas or other solutions would be very welcome. I've done fairly well at small fabrications, but this seems like a fairly complex task. Given the chance, I'll always take the duck!

Early Dart Disorder (EDD) is real, and I've got it!

You can always weld up a box out of 20 ga Iron (galv or black iron), and pipe it into both pipes with a 3/4" fitting as sort of a "crossover" pipe that will immediately heat the underside of the manifold like the heat stove....

Did this on my clifford Hyperpak intake for winter driveability.

You can even scavenge a couple of EGR fittings from junkyard Pontiac 4 cylinders that will have a stainless steel flex hose with a bolt on fitting (manifold, can go to the box...) and a threaded end (you can weld a nipple to each pipe and use a pipe coupler for final connections).

The hardest part is drilling your pipes and welding the outlets...

Alternate method would drill a 3/4" hole in each pipe, weld up a heatstove box for under the manifold and use some 1 1/2" exhaust pipe to make the connections....
