I have not seen a lot of stuff made for LA blowers. Those chevy guys can just call jegs or summit and drop 4k for a nice setup. I think you need deep pockets and or a mill and a tig welder to make a 6-71 or whatever happen on your 360 LA.

Too bad- I know ever since I saw my first one I wanted a roots blower with a big fat belt on it whining and loping away. I just don't have a hemi or bigblock. Really a bigblock is peanuts $ compared to setting up a blower isn't it?

I really enjoy seeing you guys with the holes in your hoods- somebody's gotta do it! Too bad you're not feeling the love around here- you're my heroes!!

Thanks guys for all the input but I'm sure there is more info out there. The unit for sale in the "craigslist" area is a 6V-71. Would probably make a nice street unit but it's not much of a competition unit probably not much better than a 4-71. I have looked at the manifold built in Aussie land and it is a nice looking piece, I would have designed it a little differently but it was probably designed for street use. The blower sits a lot to the rear which I believe would make it very difficult in selecting a distributor. Someone mentioned the Indy manifold but it looks to me like it is built for magnum heads. Some of the other companies make manifolds but they are very expensive. I was hopeing I could use a 12-71 that I have but it looks like it is too long. I will probably have to trade it for either a 6 or 8-71. Mr P's idea is probably the best betbecause you could place the blower exactly where you wanted it.

Please continue with the discussion there are always items to be learned from experience. Thanks, Max

You would be surprised at how much pressure you
can make with a 6/71... turn it harder but it will
still make heat... thats the problem with anything
that compresses air... it makes heat(just like your
home air compressor)... but a roots blower sticking
thru the hood will always be cool
