Thanks for all the advice. My 283 is running great and I hate to mess with something that works. It's just that water outlet. No idea what thermostat is in there and I think it's sticking open most of the time judging by the lack of real hot heat this past winter.

My quadrajet seems ok (thermo-mechanical choke). I think I'll pass on this intake.

Any advice on getting the two bolts out? Should I grind off the bolt heads on the water neck, pull it off and then? I've got a few books and they're great for replacing parts but not much info on stuff that's broken in the first place.

Thanks!
