Smog thoughts

[JBswth]

Had a shop do my 1985 K20 4x4. No big deal to the them.Removed the smog pumps,hoses and plugged the engine and i took that nasty converter off.Really cleaned up and simplified my 350 motor. In my mind i want to say it runs better but other folks will say it does not make a difference. In MD. i had to register it as a 1 ton farm vehicle to be exempt from emissions.

Getting rid of the converter MIGHT help with top end, (less back pressure, lower pumping losses), getting rid of EGR will GREATLY help part-throttle performance, re-working your advance curve can give a good boost, but removing the AIR pump won't do much that you can feel, but it will reduce under-hood heat.

I'm not so concerned about HP, I hate how it looks, I don't like removing stuff to repair something. I don't like a spider web of vacuum lines running all over the engine.... its just an annoying problem.
