Anybody run an aerospace components vac pump? How do you like it?
Also, does anyone use an oem smog pump to pull vacuum and how long do they last?
Yeah, it's got a smallblock.

I would be happy with 12 inches. I don't like those horror stories associated with 20 inches. And it's not like it's gonna make your car a whole lot faster.

Love my aerospace vacuum pump.

I have an Aerospace vacuum pump and I do NOT recommend anyone else getting one. Mine pulls 6-8" at WOT and that's w/ the regulator maxed out. My first one lost vacuum, rebuilt it, then it later destroyed itself (shaft seized). I got another one only b/c they cut me a good deal on a replacement and the cost to change to another brand of pump was real high at the time. Aerospace's drive mandrel sucks too. No way to lock down the pullies good (just a little set screw) so they'll work loose, then they gall the shaft. When the pump locked up, it tweaked the shaft on the mandrel and caused a vibration. I have a mandrel setup from CV products now...MUCH nicer and stronger. When my current pump fails, I'll probably get one from GZ.
