Why are there so few blown small blocks?

Cope said

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.
