Why are there so few blown small blocks?

-
The intake is a Weiand 7503 that I modified for the Magnuson supercharger. The pieces between the heads and headers are adapters that I designed and machined to fit the 302-351 Ford headers I'm running. Somewhere I have the manufacturer name for the headers but they are very well made, stainless headers with thick flanges and tube wall section that I picked up off of eBay for $200 (brand new).
 
Yes, twin-screw is correct. They only require 1/3 H.P. to operate during normal driving and don't generate heat like a roots-type supercharger.
 
DO THEY MAKE A OW RISE SUPERCHARGER something like the 90 92 t bird SC superchRGER ? I WOULD LIKE SOMETHING LIKE THAT WHERE i DON'T HAVE TO CHOP THE HOOD
 
The Landy kits usually but not all used an Offy dual quad 5488 manifold. This one was casted in 1984. Lower pulley was a Chevy one modified to fit SBM. Manifold is as old as me! Hahaha

I've been looking around at blown (roots style) small blocks. Lots of chevys, some fords and almost zero (small block) MOPARs.

Why is that?

I realise that they are out dated tech and now days it's all about the twin turbo, procharger ect.

As far as I'm concerned, nothing is cooler than the sound of a old school blower and the look of that big belt.

Why is it that the small blocks almost never get treated to a cool old GMC hot air pump?

I don't have a lot of knowledge about blowers, but I'm thinking that it's because mopars are just not very popular. Of the big 3, mopars have the lowest selection of performance parts that there is. Afr doesn't have any cylinder heads for the sbm's. Edelbrock has a cylinder head specifically for the small bore small block Chevys. Us mopar guys have a very limited source of performance parts. Back in the mid to late 80's the best bang for the money was the mustang 5.0's as they responsed well to the simplest of modifications.

Sure wish someone would come up with that for the LA motors for a less expensive header that would fit.
 
I don’t know how some of you guys use power steering with a 671 but I’m trying to make it all work with factory brackets. I’m having an exact copy of a factory 2 groove crank pulley made, with a flat face and 2” register to accept the blower pulley.

The hard part was trying to get a couple single groove pulleys spaced correctly, (center to center measurement of the V-grooves) to match the factory pulley. That measurement was 0.86”.

It also keeps the same diameter of the V drives. I don’t know why the aftermarket makes all the aluminum crank pulleys a different size from factory. Usually smaller diameter.

So I had this made. Still don’t know if it’ll work. Lol

I have the Hampton 6-71 kit for my 340, blower is back at Hampton's getting updated as I bought the kit back in the late 80's
Just got the carbs back from Holley, had them do the boost reference update to them
