Hello everyone- I have an RCS 170" FE dragster which I have had for 30 years. It currently has a Mopar 440 with iron heads and a single 4bbl. Not a serious build, but I did get one 160MPH clocking at Redding Dragstrip a long time ago. A friend has a early hemi motor which is already machined for 4 bolt mains and will be finished by the engine builder sometime this year. My friend intends to use this motor in my dragster which I am most certainly cool with. I will need an adapter for the Hemi-to-Powerglide. We have been planning on a Gene Adams tuned Hilborn stack injection system until my buddy bought a long time languishing project from a former boat racer.
The parts he bought were two Magna chargers and a PFM side-by-side dual Magnacharger manifold, which has a base to fit on a 14-71 blower manifold. It has two blower burst panel openings, one on each end. What is cool, besides the good looking wow factor, is that the two blowers are arranged in a 'V', which should help driver visibility. We both are lucky to live only 15 miles from Magnusson blowers in Ventura, CA.
My question is about the history of the PFM dual supercharger manifold. I have done a Google search and found nothing about this manifold, but did learn that PFM has been out of business for over 10 years.
Can anyone here offer any info and history? Thanks, -Andy Carlson, Ojai CA

I moved this topic to Matt's shop and hope he can help you with this question.

I'm sorry Andy but I've never heard of those blowers or intake.
I was with you at first with the Gene Adams stack injection tune up.
Good luck

Now a days racers just swap out the bell housings powerglide to early hemi. If you do not want to go that route, I can make a adapter motorplate for that combo, but I will need your M/P to reference off of for the chassis mounts and size and shape so it will just be a bolt in on your end.
This is a 1 piece plate I did to move the engine forward .500 on a late model hemi to 'glide, a lot of work and chips besides the cost, The 2 piece style is 1/2 the cost. But swapping the Bellhousing is the least expensive

^^^^ !00% correct on lot of chips.I made a simular plate for brothers turbo VR6(VW) to glide and had about 25 lbs in chips when done.

Found a picture of a dual Whipple supercharger system, not the best photo but.....
It's also talked about on this website:

Wonder how well this worked compared to the standard 6-71 setup.
