Default 575 sci Superchargers & Superchillers

These are all in good shape, nothing wrong with them, just thinking about moving up to bigger blowers and Eddie Young’s fuel injection. These have close to 200 hours on them now. 913-269-4748 if interested.

I believe they will fit any big Block Chevy, might depend on heads though. I am not including anything fuel related .

Are these 250's and "anything fuel related" means not including???

Also what oil are you running in them and how many hours was it changed at?

Thanks

Those are throttle bodys not carbs. They should still be pretty tight at 200 hrs. Fresh or salt? It will be easy to tell once removed. I may be interested in one set up if the price is right but new blower shop 250s new/complete are pretty inexpensive and are far superior to old weiand technology. There are a few choices on chillers.

Those are the Weiand 256 Blowers. I believe they were mainly used on those Merc 575 engines. If those throttle bodies are going to be used you will need the computers too. I dont recall seeing anyone bolting carbs on these blowers before. They are on the small side when it comes to making good power. If you are looking to make 700+ HP, you would be better off with an 8-71 blower.
