Stop in for a cup of coffee

There's only one thing I've found to be at odds with Dan. That's the manifold heat argument. But I'm only at odds with him regarding performance oriented slant engines, not stock or mild. I don't care what engine it is, once you get past a certain level of performance, they all benefit from blocked intake manifold heat from the exhaust. It's a thermodynamic fact. See how I worked that big word in? Now I feel smart.

But seriously, as in my very recent battle against detonation in my hot slant 6 build, were I to remove that block off plate, the engine would detonate again and it would not produce the power it does now. In my situation, living as far south as I do, it has zero effect on how fast it warms up. One argument was the choke wouldn't work well. It's electric. Plus, it's adjusted all the way open and not hooked up. LOL

On a stock to mild engine, I'll go along with it......but even where I live, they can benefit as well. I even have manifold heat blocked of on the 351M in my Ford truck. No problem at all and it even helped the engine temp drop keeping all that heat out of the intake. IMO, it was a stupid idea for vehicles operating in warm climates.
I guess its to improve atomization of the fuel until engine is fully warmed up. My 51 flathead has one,that tells me it has little to do with emissions. Mine is wired open as it likes to stick.
