Re: [AMC-list] exhaust ports...

[Frank Swygert <farna@xxxxxxx>]

Just the opposite -- sounds well within reason. I don't think I'd worry about the furnace cement though. Since the insert will stay in place by shape, don't worry about a little exhaust gas or heat rising into that well. You main concern is flow, right? At anything above idle exhaust gas velocity will be increased to a point that a small "crack" along the leading edges of the insert won't matter. Fit the insert as close and tight as you can and it should work well. Some heat will transfer above it into the cavity, but that should be a plus -- it will still warm the intake tract and especially the critical area right below the carb. That's where the intake charge hits the floor of the intake "trough" first and would tend to separate on a cold intake floor, vaporizes better on a hot one.

Anyone see anything totally hare-brained about this idea?
