Is anyone using or seen the blower manifold in use that's sold by Larrowe and Sons? Curious as to how high everything sits and how well it works for the street. Looks like my McCulloch blower will need a major rebuild so looking at options.

I have referenced that manifold here many times on different posts. Here again, http://prostores1.carrierzone.com/servle...manifold/DetailI do not think it will clear the hood on any "normal car" ,except maybe a 55 Chevy & the likes or a truck. I am sure it will work fine w/a blower forcing the air/fuel charge into the engine. When I had my Paxton rebuilt IIRC,it was about $450 but that was when Paxton would OVHL them,last I heard a Co called Paradice something OVHLS them, not Paxton. MBHD

The overhaul quote I got was $754.78, about the onlything re-usable is the housing and pulley, talked to Dick Larrowe and made arrangements to meet him next week and measure the whole set-up. Then the next problem would be to find a small B&M blower for a Ford. I may run into the same rebuild problem as B&M stopped production on the 144's.

John Erb in Carson City is a McCulloch guru. He is not cheap but is very good. He has made lots of improvements on them. My son worked for him and picked up a few tricks from John. If you decide to get rid of yours let me know. Is it the one you got in Reno? Beater

Weiand blowers are still being produced & I think has the same bolt pattern. http://www.jegs.com/i/Weiand/925/7750-1/10002/-1B&M used to make all differnt length snouts that would work on that manifold. MBHD

The one designed for the Fords had the drive on the left looking from the front, the chev was on the right and they stopped production after the B&M/Wieand/Holley shuffle. They make a 174 but are really designed for a larger displacement engine. I could change pulleys but then the effeciency of the blower would decrease with impeller friction.

Would a 3 or 4 71 work?
Or are you trying to stick with the smaller huffer for hood clearance?

That would be a deciding factor, it's for a '58 Chevy, Dick Larrowe said there have been some 4-71 blowers adapted for use and after I measure one (intake) maybe an Eaton M-90 or M-112?

I have a B&M 144 sitting on the shelf if you can't find another.

I saw a Weiand blower the size of a 144 on Stacey David's Gears today.
I know it was a re-run, but it should be on the web site.
I hope that helps.
Happy holidays.:)

I kinda gathered that after measuring one, nice car, want to keep my hood closed (58 Delray) and use year round.

Looks like a Nicson dual carb intake manifold - fins removed and polished. Is that a 235? 261?

This is a 235 with an Edelbrock manifold. Carb mounts and surface milled flat. The adapter plate and manifold are cut out under the Magnacharger. This gives me carburetor/intake heat. I am experiencing some fuel condensation in the carburetor plenum with the hood removed at temperatures below 50 degrees. This project has been a learning experience for me. More details/BS at 1934chevrolet.blogspot.com. Of interest, this setup loves 110 degree Vegas temperatures.

Thank you, please understand that I am not as experienced as the rest of you in supercharging technology. I am currently operating the unit at 1 psi in an attempt to improve the breathing of the engine. Yes, it does work and I am enjoying the project. Thanks, Jerry

Obviously, we can't see the blower port/manifold discharge surface, but Eaton exhausts almost directly behind the front bearing plate. The remainder of the port tapers off. Is the port right over the front carburetor flange?

Design factors: 1. Supercharger location controlled by the serpentine crank/supercharger pulley centerline. 2. Maintain suitable gasket surface and mounting hardware for the adapter plate. 3. Mount supercharger as close to head as necessary to clear '34 hood and grill shell. 4. Use the existing exhaust manifold to insure intake heat, supercharger support, clean quiet single exhaust.
Then cut intake manifold from front carb port back to 1" behind supercharger discharge surface(yes-mp90 discharge over and to rear the front carb port). Match cut the adapter plate to the intake and supercharger cavities and flare the transition out bottom to top. I am aware of the technical drawbacks here, but this is a cruiser and it achieves my goals for less than $1k. Excellent drivability.
