The V8 Owners Forum -

Great, thanks Chris, much appreciated.

Thanks, that's really helpful.

I'm presuming this is the bypass you're referring to - from the front of the inlet manifold to the water pump housing - so I should be OK to stop the heater matrix flow?

This is really helpful Gents, I think it's answered a question for me... I've got a Rover V8 from an SD1, 3.5l carb-fed in a 7-type kit car. It has an Offenhauser dual port inlet manifold, which has coolant connections front and rear. I didn't build this car. The rear connection goes off to the heat...
