I run an Offy manifold with 625 Carter AFB (about the same thing as an Edelbrock 1406) on my 292 and I love it. You'd have to beat me senseless before I went back to the Monojet.

I don't use water heat. But the electric choke is a wondrous thing, especially in the climate I live in where the temperatures fluctuate wildly. It's nice to be able to get in the truck, twist the key and drive off without having to warm it up (within reason) and drive it while it's cold without a lean backfire. I use a throttle pedal and bracket from a 74 C10 and a throttle cable for a 73 Monte Carlo. Works great.
