oh that looks nasty. Not addicted to chirp and burn (yet), but that does look like a fun little set-up.

Bias ply's are way better for traction on any surface that is not prepped well for drag racing
Been their, done that
My old 3450 lbs. with me in it and a full tank of gas, pump gas Duster went 9.993 at 134.7 MPH once at Woodburn Drag Strip in July several years back, the track told me to not race it anymore as it was NHRA legal to 10:00 at or below 135.00 MPH. I staged it a little deeper and shifter it a little later to run several 10:00 that day in completion on the brakes
That car exceeded all my expectations every time I changed something on it to run faster or quicker

That's my old B&M/DLI blower I ran in the early 90's on my 446" RB Charger I sold to 6BBLFlash I don't remember how many years ago. So glad he's still having fun with it since back when I bought it directly from "Dandy Dick Landy" Hisself!!

I remember I drove it (without a hood) to the Mopar Nationals in Columbus from Charlotte way back in I think 91 or 92?

I really miss that "Mad Max" sound it made going down the highway. And passing gear was....well lets just say passing me was by permission only!!!!

I'm glad to see it in the 10's now! That's so awesome! To run 10's with such amazing street manners is really hard to beat for the $$$ and fun factor. I know you had it running mid 11's for a long time I'd love to know how you got such a mildly geared B body turning those kinds of times!

I'd love to find a smallblock version of the 174 Kit and put it on my 414 in the Rocky.... but I'd need to take a bunch of gear and converter out of it.


As for the bigblock vs smallblock debate , with today's stroker kits and heads it's all a bit blurred. The issue with a smallblock for me was there's not really a whole lot of lightweight Mopar bodies to start from, But I generally prefer driving a light car/small motor over a big car/big motor, ...except for just cruising with my buds, and for that you can't beat a big block 2nd gen B body!!

The sheer torque of a stroker BB is so much fun on the street and I love the "potato, potato, potato" sound it makes.

Third gear pulls on the highway just easing into the throttle are a religious experience. Nitrous is the cherry on top.

It's fun to blow past modern "supercars" that think they're going to gap your old dinosaur. They get kinda upset when you tell them you had another 300 in reserve that you didn't even turn on.

Hey Bobby 👋🏻.

Lots of trial and error in getting a 10 out of this thing.
9.1 cr,,Stage 6 heads, 2" Hooker headers, Comp.236/242@.050 solid.504 lift..I think 🤔.
4150 Chinese Holley 1050cfm .,Turbo Action tight 10"converter.
3.33 Dana out of a Ford truck.
Blower is pullied 2.72 x crank speed...it's humming along.
Have seen 9lbs in cold temperatures.
6 lbs is normal...
It doesn't like to be shifted above 5,000.
Boost doesn't fall off ,but it really hits a wall at 5,000.
Might be valve train. Want to try more seat pressure on the intake valves to counter boost.
Want to explore E85.
Want to make my own intake manifold.
Want try 1.6 rockers on the lean cylinders only.
Want .....to push the crank out of the block before I am happy 😊 lol....

I always toyed with just porting the manifold and making a short phenolic spacer between the blower and the manifold using the gasket as a template, the blower gets hot and transmits that heat right into the manifold and the air density (mass) suffers. Any increase in the air mass below the blower increases power. Yeah I would want to try a stiffer spring, but really if you're only getting 5K...5K at that kind of pulley ratio you're really building a lot of heat do the efficiency of the blower is going way way down. 5K at the crank is like 14K in the blower and I think it's only rated for ~ 10K continuous and 12K for short bursts.

I figured If the spacer helped power, fabbing some kind of water/methanol cooled intercooler (with a small electric pump recirculating through a chilled reservior in a closed loop) would really help, then you might actually slow the pulley down and still make more power.


I've learned a lot from watching Gale Banks videos on Youtube, he speaks mostly about diesels but it's all applicable to N/A as well.

I miss that little blower I was fun and OMG did it make instant torque through the middle!! To me It felt like a strong street 440 with a full time 100 Nitrous shot any time you hit it.

FROM my experiance with a screw blown 4.6 mustang, a blower with positive displacement is the way to fly. I am wondering how a stroked 5.9 magnum wirh EQ or aluminum heads at 408 cubes, and blown, would hold up. Rpm could be kept pretty low and torque could be very good from off idle on up. That Mustang was a blast to drive, and a little 281 made 475 hp at the crank on pump 92.

Haha.

Same!

I agree with the station wagon analogy.

Any pics of what the OP's car looks like? If it's "stock-ish", then the blower under the hood maintains that appearance. The extra weight of the big block will likely change the handling characteristics of the car on the street, if that's of any concern.

FWIW, I checked out the specs of the blower mentioned and it says it needs "premium" grade fuel; does CA 91 even qualify?

I’m thinking since I have time this week, went down and checked out the duster. If I remove the 37lbs of rat turds and pull the a/c parts off, the added weight of the supercharger assembly will be pretty close to what is was prior installation. Going to start another thread on small block build-ups.

Turbo big block.

Our gas is crap, worse it the winter. We are at sea level and have access to liquid power adders and have blended a few types of fuels before, so I don’t think that will be an issue.

The ultimate street car runs a blown HEMI!

I have a B&M 162 on a 408. It’s too small. It’s overdriven the most I can get it, makes 4-5 psi. It’s fun in my ‘74 W-200, it really moves out. It’d be even more fun in a car.

So I’m building another 408 with a 671. TBS billet blower, high helix, Teflon stripped. For the cost of the blower alone, had I known they existed for carburetors, I woulda went with a Whipper screw blower for a couple thousand more.
