Crankcase Evac Pump

You may want to pose that question on Yellowbullet.com , I only know of maybe 2 to 3 guys on here that run a Vac Pump... One of them is me. There are way too many stock is the way to go guys on here. Out of the box questions and scenario's its best to visit Yellow Bullet where guys actually do the stuff and use it. You are WAY past stock works best. LOL You will most likely be doing a 1 Off custom install on your set up. I had to totally modify GZ's bolt on kit for my engine. Had to visit a Lathe and machine down the Mandrel as well as modifying the pump bracket and getting a different size Cog Belt to make it all work.

Yes I'm forced to run a racing setup on what was supposed to be a street build. The area below the alternator is real tight but I think we can do it with custom everything. From what I've read a big loose engine like mine will be ok if I get the vac pump. GZ says that my cold leakdown numbers are fine with a pump and that a big cube engine that is as loose as mine must have a pump. If the pump doesn't work then I will be forced to pull engine and tear down. Honestly, it runs really very good on the street until it blows a gasket.
