Not that I'm aware of. Yes, the modification you described it was I did to mine. The process is the same whether using a roots or screw type supercharger. It's not difficult. You just need to be careful how you do it and make sure that all surfaces are true and flat when you're done.

Dyers Blowers would take the available intakes and mill(?) the top away and attach the plate for the 6-71.Maybe they could modify your intake...the drive should be the same unless it's for 70 and up only.
 
thanks for the info , but i can get it done locally , i have machinist buddies , and i have some equipment that can do the job but thanks . pm

if the chevy LS intake is adaptable to the poly then just get a blower intake for an LS.

You're right, that is certainly one option. I think the member asking about the roots-style supercharger was interested in the look of the earlier models. They do look great but come at a size, weight, and H.P. hit (due to parasitic loss). My twin screw requires 1/3 of 1 H.P. to run. A traditional roots style requires 25 H.P. or more depending on supercharger size. Roots style also generate more heat.

i guess with the LS being 'modern' there are screw type blower intakes available too.

Nat: I know that Dick Landy Enterprises made a supercharger "package" for the LA engine many years ago. I hear they do occasionally appear for sale but it's not often due to their manufacturing quantities being very low. Your best bet (IMO) is to find a dual 4 barrel manifold for an LA and the supercharger you'd like to use and then have the manifold modified to fit that supercharger. The work isn't all that difficult. You have to make sure that you; 1.) Provide enough space to clear your distributor and 2.) (the most time consuming) Make sure your supercharger is "square" on the manifold and 3.) Make sure your belt to pulley (alignment) relationship is good. After these items are completed, it's all a matter of bolting on parts. You do need to be aware of the overall height of the engine with supercharger and carburetor or injection. I spent (alot) of time on mine since I wanted a "sleeper) that didn't have a hole in the hood.
