Looks like fun! I would like to try fitting that under the hood of my '42 Chevy but I am way too poor for even dual carbs let alone a blower

Lock out the dis curve and set the timing at 28 to 30 or get a boost retard box for it...for the street.

The carbs will need set up including getting rid of the choke horns.

If you are worried about the rear end take power out of the motor.
Reduce the blower drive ratio. 5-6 psi is plenty for street play.
Don't make it more $$difficult$$ than it needs to be.

K.I.s.s.

Check the blower belt at a minimum, if not replace it entirely. Pop the distributor cap and take a peek in there. My friends dirt track car had a VERY rusty MSD distributor after about a season...One of the blower guys here can probably talk to you about hot start issues and blowers, may or may not be a problem for you.

NO ONE regrets getting a blower...

A GM 7.5 will take a lot of power. The gm oem posi will not.
The axles are not the weak point. Axle wrap -wheel hop must be eliminated.
This eats any axle. Its a matter of setup.

Its wheel spin and grab and wheel hop ABUSE
that kills rears, not power ,with traction and axle control.

Small update
Blower is off and sold
Weld wheels are off and sold
C3 exhaust is off and sold.

I have ordered and paid for the following
76mm GT45 Turbo
Large by huge front mount intercooler, charge piping, couplers etc.
Oil feed and drain lines.
Forward facing turbo headers.
Complete fuel system including twin Walbro 255's, sump for tank, 8AN and 1/2 hardline feed and return, aeromotive bypass reg.
Assortment of vband clamps and flanges.
I still need to order the Carb and Carb hat.
Will have the motor out of the Vette in a couple weeks, then I have the shell sold for 1500.
That 1500 goes to the CSU Carb ($1000.00 jeez us) and Carb hat.
Goal is a 700rwhp street car
Stock appearing right down to wheels
Only non stock is 2" lowering and small cowl hood.

That is one hell of a deal you made.And this is coming from a oldtime horse swapper that has changed the saddle on so many horses I've lost count.The car itself as a roller should be worth a decent amount of cash.

Have good time !

Yah, around where I live an average BBC on a small hit of gas is a huge deal, we don't exactly have many fast "street" cars....the stuff we do had that's fast gets trailered everywhere....so this should be pretty cool.

Have tyou looked into EFI. You are not too far off for what parts you have. EFI will make tuning so much more stable, i.e. the tune is only as good as the EFI tuner and dyno operator.

I did an EFI BBC 871 project for my Jet boat. After the dyno session this thing started and idled rock solid, no surging or anything. It had 12psi of boost and was a violent ride. After a hard run I would idle it to the sand bar where the hang out was. Never stalled, never sputterd or nothing.
Since sold the bolt and parted it out. To many other projects. However if I were to do it again it would be a turbo. Blowers look cool but...

I did consider it briefly, but I'm completely mentally challenged when it comes to injection.
And tuning along with the initial cost of getting started made me stick with a Carb.
For the most part I have heard nothing but amazing things regarding CSU carbs in regards to power as well as driveability. I do want to go with an injected LS at some point when this either breaks or gets boring but have a ton to learn before that happens.
