Been a minute since I have been on this site. Got busy with life. I've had a 350 Engine apart I've been building sitting on my friends workbench for a couple years now. Well he's moving and I need to shit or get off the pot on this project. So I decided I better get it put together. One thing I've been needing is a intake for the 38mm carb I bought for it. And I figured I'd keep with tradition and build what I can so I can buy what I can't build. This definitely has me motivated to finish the retrofit on my CNC mill. Still have some more work to do on it.

Looks great Pictures of the mill when you get a chance When test running keep a eye on jetting, running better might be a lean condition caused by design including increased vibration and harmonics at the carb itself causing fuel foaming = lean condition = Poof Kaboom = cuss cuss cuss...

The mill is just a regular Bridgeport. My cnc is also a Bridgeport but it needs some new electronics. I never considered the increased vibration. I wonder if anyone has done any real caculations to see how accurate the balancer shaft really is. I would think too as the belt tension increases that would also help with vibration. I personally have had fairly good luck with these engines. Most of mine have water-cooled heads. I run redline synthetic and avgas. Most are completely stock other than the heads. |

Hey jknarfal: I don't want to be the fly in the soup here but make sure the base under the rubber boot is a full base. That was the design flaw in the aftersucks intake. The boot did not have a full platform to sit on so when you tightened the boot to the aluminum, the metal plate in the rubber would flex. This caused a gap and you leaned out your Engine. How do I know ?? My brother bought one of those pieces of shyte and it cost us an Engine. I did do a thread on it. CO |

This flange is different from what I see most people have used. this is from a Polaris. It metal backed and has a groove for a oring to help it seal. It has a full area to seal against. I have not drilled and tapped the holes for it yet so if it's off a little in the pictures it won't be when I'm done. I also found a 90 degree elbow that should work with the new carb. |
