Not really. The impellers can be used in aftermarket cases but that's about it. Nobody makes intakes for them but if you're inventive you can cook one up yourself.
Cut out a plate that bolts to the bottom of it with counter sunk screws and to standard 6:71 manifold hold downs. Not hard I think. Never done it though.
I have several, when I can dig them out for a picture, I will try to get one of the pile and post it. I don't know if they are complete even.
Good blowers! Get youself a piece of 1 in. thick alum., sit the blower on it, after you have put dykem on the plate, get out your sharp scribe and trace around the bottom of the blower. On you engine that you want it to fit on, pull off the carb, remove the carb studs, and water inlet on the front of the intake. using a flexible machinists ruler, center the plate between the valvecovers, and give yourself a little clearance for turning the dist. (Use a small dist., if you can!) Make a mark, both front and rear on the plate marking the centerline. Be sure to doublecheck all measurements! Now, peeking over the valvecover, looking under the plate, scribe a line eyeing the front of the carb. mounting surface, on the side of the plate. Do the same for the rear surface. You now have 2 marks on the side of the plate, using a machinists square, scribe these 2 lines across the plate, going valvecover to valvecover. Now, you have some reference lines so you can lay out a carb. base gasket that fits your intake. Now, look under the plate agian, measure the gap between the bottom of the plate and the top of the intake ahead of the carb. mounting surface. You will want to mill that much off the carb. mounting surface, so that the plate will sit flat on top of the intake runner. Write this dimension down, and don 't lose it! Pull your intake off, indicate the bed in on you mill, mount your intake up on 1x2x3 blocks, indicate everything in to at least .003" At this point, you must make a decision. You can either mount the plate where it mounts like a carb plate, mill out a hole where a carb gasket will go. You can mill the carb mounting surface down to the top of the runners, to give added support to the blower plate. Of course, you will have to layout countersunk carb pattern mounting holes in the plate, and a couple of countersunk bolts up at the runner area for added support. This is the route to go if your using a cast iron intake! Now, you can choose, if you have a alum. intake, mill the hell outta that sucker to sit that plate down in there, tig it in, mill out your blower airfeed slots that line up with the bottom of the blower and the mounting holes. And you'll have to block off the thermostat housing area, mill out a area on the extreme front of the intake under the blower for your water intake OR you will have to tap into the heads at the front. Its extreme, but its good. Blowers are good. You just don't throw them on and cruisin' , yu have to do a little work. 8-71's are great blowers, I ran one for 5 years on a 455 pontiac.
