Re: Emissions problem
I have removed the entire pulse air system, and plugged the exhaust manifold, and the connection at the cat. I found that with the cat sucking air all the time, it gave too much air to the cat, and it got really really hot (the air helps the cat do it's thing - so it was burning off too much stuff (?)) Anyway, it was glowing red.
You can get adapters to adapt the weber to a standard 4" diameter air cleaner if you want, and maybe connect the orig air cleaner (?) and some more of that hot air stuff. I just left mine with the standard supplied square one.
I run the weber and a GM HEI, and I passed the dyno test on my 88.
I've still got you beat, though, 207,000 and counting (but the motor and axles are new - the tranny and transfer has that mileage, though.) [img]/wwwthreads_images/icons/wink.gif[/img]
Not saying this is the way for you to go (legal disclaimer), but it works for me. I passed the sniffer, and that's what should count, not what's under the hood.
