Thats nice machine work !
Very Nice, This is filling in the puzzle I have always wanted to know, I have a book on overhauling a blower for street use but it stops shy of the blower drive, never been real crazy about thinking I was going to have to tear into my working 6/71 on my '32 just to see what it would take to machine a drive. I have a front cover already and a 392 laying around....Nice work and thanks for the info & great pics! Matthyj
Wonderful cad work

Got the blower case back from the blasters so set about doing some modifications to it, First the support bar in the intake side was removed, its not needed now its not hanging on its side anymore, once out the edges were milled to clean it all up.

Heres a pic of a stock scavenge pump setup incase you have not seen one.

My small mill doesnt have enough throw to flycut the intake angle out so popped into my mate Brians shop and used his. While I was there the intake throats were bored out from 1.250" to 1.500", the bottom plate of the plenum was bolted in place and both bored together to keep the throats aligned.

Correcting the intake angle meant losing the rear stud hole, we spotted it through first and retapped, Will weld a bung in here at some point.
The dividers in the throats will be ground to a knife edge so as not to disturb the flow.

The bracket bosses cast into the intake no longer serve a purpose so cut them off and blended them smooth, this uncoved a hole so it got welded shut,

Here the plenum sides are tacked in place, the tricky to get at bolts are now much easier to get at as they go through columns.
Couldn't do any finish welding as my 200amp isn't gonna be big enough as the aluminium is 1/2" thick, gonna need a fair bit of preheat on it.

Looking good. Just becareful, the critics claim those intakes don't work well................. Mine worked fine though. :LOL: You are doing awesome work on it!
.sorry double posting
More progress, I tacked the plenum together ready for final welding but due to it being 1/2" plate my 200amp machine was not gonna do the job without a lot of preheat so it was off to see Mr Miller Dynasty Got it all welded together late in the evening eventually, then had to drink numerous cups of tea while it cooled down Thanks Gary

One of the mounting lugs on the intake had been damaged at some point so this was built up with weld and reshaped.

The bottom plate thats bolts to the inlet bowed by about 20 thou over the length so it got a small fly cut on the mill. If you have never seen flycutting i've added a short video below.

I mocked it up to have a look and discovered the front plate is a little shy in 2 corners so will have to make up a couple of bits and welded them in.

Next up was the snout drive shaft, its 1.250" steel bar turned done to be welded in to the hub at the blower end, the other end I have to broach a keyway into, made up the pulley flange. the shaft has been left long at the moment so I have something to hold on, I will shorten once its all mocked up on the motor.

I was a little concerned about the mounting bolts on the intake not being very far apart, probably be fine but just to be sure I added a pair of braces, they have to be welded to the intake yet, they bolt to the 1/2" blower plate with 2 x 1/4" bolts.

Here it is mocked up in place ready to measure for the snout length.

Wow you're sporting some awesome aluminium work there, this should be a fast beast when your done!
We played around with the iphone video a bit last night and were surprised at the results we got !!!

The amps had that torch singing on that base plate eh?:)
I hope the viewers also noticed those practiced hands guiding the torch and feeding the filler...............very skillful my friend.

I'm running a MSD blaster coil and a MSD 6A ignition box behind the dash out of sight. Will paint the top of the coil black later.

Was going to make a carb plate for the 2 x Edelbrock 94's but found one of my suppliers made a nice carb plate already and not expensive, check out Dashmans hotrod parts Dashman's, Hot rod and custom speed equipment parts
