Welp??? Will it work? The short block is basically stock, just a thin hone job. The cylinder heads have been ported and polished, with stock runners and diameter valves. I was wondering what type of carburation I would hafta run on the blower. Nothing drastic, just enough to run healthy.Any help would be appreciated.

 

Why would you want to put such a huge blower on such a small displacement engine? The blower would cost more than the rest of the engine.

You could probably make the same amount of hp as a well built 400.

 

point of his project is probably to build something different. go with a dual 450 four barrel setup, that should be good enough, if you were to do anything big with it then you may want to go with a set of 650's. i was going to build a 305 with a 6-71 and camp stanley (nmca's blower guru) told me that's what i should go with...

 

anything will work, just a matter of enough time and money to sort it all out, hell you can run in the 4s with a 9v radio battery if you had enough time and money. it sure would be hard to move very much air in a 283. i'd at the very least consider soemthing with a 4" hole and large valves.

 

6-71: 6 cylinders, 71 cubic inches each (Detroit Diesel). 2-cycle, so one power stroke per revolution per cylinder. 426 cubic inches.

You'd have to underdrive that thing something fierce.

There are reasons why some things are "different", and why some different things don't work.

 

Nothing like the sound of a detroit. Oh course I'm going deaf in one year from working on them so much in the 80's.

The number of the blower doesn't mean much since it's the amount of air it can push that makes the biggest difference. If you look at the little Weiand street blowers, the SBC versions are 142 CID while the BBC ones are 177 CID.

671 blowers are usually 12% underdriven on SBC and 9% underdriven on BBC.

For an extreme you could even put an 871 blower on a SBC but the pistons would probably have to be about 6:1 compression.
