Desmogging a 250? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Anybody out there have any experience desmogging a 250? My '74 has a smog pump, tubes into the head, and an egr, etc.

Here in Portland, my '74 is exempt, and the stuff can't be doing me any favors, not too mention it's needlessly cluttering up my engine bay.

Wondering who's been down this road, and if there's any pitfalls to worry about?

It looks really straight forward to me: Pull it and plug it and tune it up as normal.
