STYRENE-SURFER Posted October 22, 2019 Posted October 22, 2019 (edited) Its great that this has become a pinned thread. Tho it would be nice to keep it concise without all the banter. We can all ask questions on another thread and then add any info to this one to keep it tidy. Edited October 22, 2019 by STYRENE-SURFER 1
afx Posted October 22, 2019 Posted October 22, 2019 (edited) Correct me if I'm wrong but I believe the supercharger in the Revell '57 Ford Fireball Roberts kit is a Paxton unit. http://manuals.hobbico.com/rmx/85-4024.pdf Edited October 22, 2019 by afx
Jantrix Posted October 22, 2019 Posted October 22, 2019 The AMT '37 Chevy kits come with a very nice Offenhauser? finned valve cover, dual carb intake and split headers. They definitely look like vintage aftermarket equipment if you are into straight sixes.

Greg Myers Posted October 24, 2019 Posted October 24, 2019 Let's start with this one from an early AMT '40 Ford I have no idea what type blower this is supposed to represent.
Greg Myers Posted October 24, 2019 Posted October 24, 2019 Here's another from an early AMT '57 Chevy kit
Deuces Posted October 24, 2019 Posted October 24, 2019 GMC roots type 4.71.... Any shorter on length, it would be a 3.71....
Greg Myers Posted October 24, 2019 Posted October 24, 2019 Maybe I should have started with this one from AMT's '25 Tee kits. The Latham Axial Flow Blower was kinda different from most blowers modelers were familiar with.

larman Posted October 24, 2019 Posted October 24, 2019 The one in the '25 T is a Latham blower, I believe the one in the '57 Chevy is supposed to be a S.C.oT blower, The one in the '40 Ford may just be generic, I haven't really seen a real one like it.
Deuces Posted October 24, 2019 Posted October 24, 2019 Ok.... Maybe a generic 6.71 roots type blower.... I need my glasses...??
Ace-Garageguy Posted October 24, 2019 Posted October 24, 2019 (edited) 1) Blower in first post is a generic "oval case" GMC 6-71. The junkyard cases varied considerably depending on what the blower was originally installed on. Remember...in the early days, these things were salvaged from trucks, mining equipment, military landing craft, etc. Front drives and rear covers varied considerably too. The mounting flange on the oval-case units isn't seen. 2) Yup, the one in the '57 Chebby is supposed to be a S.C.o.T blower, but it's not a very good one. The real unit has a lot more ribs. Replicas and Miniatures makes one that's a real jewel. 3) And yes, the '25 T kit has a Latham Axial Flow unit. These didn't make much boost at low RPM, and were expensive to manufacture. 4) The "doesn't look the same" unit is a bottom-flange style GMC 4-71. This mounting flange is more common than the oval-case style on old race cars, but the internal workings are the same. EDIT: For reference, the Potvin (and knockoff) crank-driven blower rigs usually...but not always...used the oval-case blower housings... EDIT 2: Here's a shot of an oval-case unit mounted like in the first post... Edited October 25, 2019 by Ace-Garageguy
afx Posted October 25, 2019 Posted October 25, 2019 Not my work but here is the R&MCoMD S.C.o.T. Blower 1

From the kit it's just popped down on the manifold where the carbs go, but theres no clear mating surface.

afx Posted October 25, 2019 Posted October 25, 2019 (edited) Latham Supercharger: https://www.jalopyjournal.com/forum/threads/latham-superchargers-registry-info-pictures.315062/ Edited October 25, 2019 by afx 1
Greg Myers Posted October 26, 2019 Posted October 26, 2019 Those Chevy Fuelie manifold bottom sections make great Man-A-Fre induction set ups
Greg Myers Posted October 29, 2019 Posted October 29, 2019 and a lot of kits came with really BIG blowers.
