zildjian4life218 This is awesome! I wanted to do something like this to a stock 350 just to do it. Plus its always fun fabricating something from scratch and making it work. Good luck and keep posting pictures.

67MercCat Thats good to hear, I called the guy who had one and it sold quickly but I have my eyes on that machine. It cuts the gauge of steel I most often work with. I think it woul be perfect in cutting plate steel to make brackets and intricate shapes.

nine4gmc cant wait to see how you work this. my neighbor has a Spectrum 375 that we are trying to get together on the price right now...I want it like no tomorrow but my pockets say I gotta wait or sell something else I probably need...

NewInteriors(Randy) mentioned in a thread I started on this machine, that he has one and loves it. If you have ever seen his work, you'll know it must be pretty decent. Ask him about the quality.

67MercCat okay, I just found out that the compression on this engine is too high for boost, but a pretty good engine although to boot!

67MercCat now does anyone know much about the Miller Spectrum 375? I'm looking to get the tools to get this project going and I think I'm going to need some decent cutting power. Anyone here own one and can comment on its quality?


This is the victim uuh I mean engine I'm using 429 Thunderjet

reviving the ol thread

okay guys I'm resurrecting this thread because I finally found all the parts I need...from the junkyard haha So It's the two turbocoupe intercoolers and some piping from the 3.8 supercharged Thunderbird and the 2 m90's. I'm going to end up buying some more piping from my local metal supplier and off to the races I go!


Here's the general design of how I want it oriented

back to business

My original plans proved to sit up too high for any dream of ever getting the hood back on.

I got a hold of some ideas for the serpentine belt set-up from an old Fox Body mustang I just picked up recently. I took all the accessories including the power steering pump, the alternator, Idler pulley, the water pump pulley and crank pulley to match the S/C (6 groove set up).

I plan on mounting it like Mike but his plates are designed for the Thunderbird 3.8 supercharger. I'll be mounting them to the heads like he did.

67MercCat here's another guy who put the juice on the 302...

67MercCat okay I went to M&K Steel Mill and got a hold of some 10 gauge steel plates I'm going to finalize the templates and trace them onto to the steel using an awl.

Since the snout has a sump the allows the blade gears to sit in the oil and kinda offset, I'm going to have to make the bracket work somehow. Maybe a cut it out or on the front side of the snout.

lowROLLERchevy I would say 3/16 or 10 gauge (.1875 or .140) Since the mounting plates are attached on the same axis as the rotational force you dont need much, Once you get some sort of a side or rear bracket that bolts to the intake / exhaust bolts it wont go anyplace.

That will keep the oil in, and vibration won't affect it since it cures to a flexible gasket.

And yes, I registered just to say that.
haha welcome to the forum! thank you for the info!

67MercCat thats a good idea, I'll take that into consideration in my design. I'm going to the steel mil today to pick up some plates. How thick do you think the plates have to be to support the S/C. Each one is at least 35 pounds and their going to be under high rpm torque.

I'm still dancing around with a few ideas about the mounting orientation though.
