440: Best roots style blower

[RonnieK]

Who are the best (and your favorite) places/people making roots blowers for a 440? Doesn’t seem to be very many at all.

The Blower Shop has some nice blowers!

X2 on The Blower Shop. A friend has a BDS on an early Hemi, after 10 yrs they didn't want to do any customer service or updates. TBS was very helpful and offered rotors in 90* and 120* twist.

I'm running a BDS 8-71 with a TBS 4" spacer. Dealt with both companies with no problems or hassles so far. Both were very helpful with advice on motor build.

We’re using an old GM blower going to look like this one when done. But mines more of a vintage type build

With a street car just about anything will work. My small block has a prehistoric 6V 71 Dyers unit. The lower clearance is pretty loose. It's mounted on a modified single 4 barrel intake. It'll still run 11.0x@122, 3880lbs thru the mufflers. The motor is very mild. 344", home ported factory iron heads, .550 solid cam, 8-1 compression.

Mert Littlefield Blowers
Don', Hampton Blowers
BDS
The Blower Shop, when Al Hoffman was alive
(IIRC) at the time they were the only people still
(Now a few do, INDY is one)
making a blower manifold, with a pop-off valve for a RB/B engines
'not the burst plates'
(if you ever run it in the cold you will wish you had one)
But all the above have or had great blowers/roots style
may different rotor angles & sizes etc.

most all of the org. founders are no longer with us
either family or another ownership completely etc. now

I used to use a shitload of Mert Littlefield blowers (top-notch)
they were in SoCal too, so my shipping
or my ability to go down & pick stuff up was way easier, & cheaper
over the years, 6:71-8:71 to 10:71-14:71,
from 10% undriven to 50% overdriven in either 8mm or 3"
they ain't cheap, don't even attempt to bargain shop there
mostly for racing, Methanol (or Nitro) 'lots of boost',
not much streetcar wise, take a lot of power to spin them
hard anodized cases & timed/hardened gears, Hi-helix rotors &/or Teflon strips,
better billet materials
but it was/still is the quality stuff

good Luck

I have a 1071 BDS on my HEMI. If I were to do it again I would go with the blower shop as their case is billet and polishes up much better and choice on rotor twist.

I can never live in the now.. i squirrel my money away and go as cheap as possible.. i think growing up broke sticks with you through life Am considering throwing down my CC for a 408 or maybe a 400>500 stroker though.. i don't need more than 500hp for stoplight fun

Yep I know what you mean. My GTX has the 350hp 440, I’d love to at least put a little more cam in it, get at least 375hp. But it does burnouts the way it is, and it’s loud, that’s all I really need.

A blower would be nice too, I’ll just drool over y’all’s, if y’all don’t mind.

It’s a 63 dodge engine compartment the same as your Plymouth’s.
