Thermostat housing for Offenhauser 360 manifold
Hi, can anyone advise if it is possible to use the standard thermostat housing from a 3.5 SD1 manifold on an Offenhauser 360 with a four barrel Holley? I am currently in the middle of fitting the Holley and manifold on my SD1 engined Landrover.

The bypass allows limited circulation before the thermostat opens, with a small diameter hose going from the thermostat elbow to the rear of the water pump.
If my understanding is correct this is to prevent localised hot spots in the water jacket in the heads before the entire body of water is hot enough to open the thermostat. If anyone can explain it better I'm all ears (or eyes )

It's not a bodge if no one finds out!
I have an Edlebrock manifold with std housing. This setup has the same problem but I have drilled a couple of holes in the thermostat allowing some bypass flow. Works nice. (This is an old trick with A-series engines where the notorious bypass hose used to cause problems... simple remedy is to ditch the hose, plug the hose inlet/outlet and drill the thermostat.)
