Who has actually built a mild roots blown 455, 5-6 psi. I want to use a B&M 174 series so it would be as short as possible and I mostly have it figured out how to keep it under the hood. What I'm interested in is, how you made the intake, how you ran the belt drive system, how you cleared the distributor, how long was the drive snout, etc? Thanks Brent
On TA's Facebook sight there is pictured a twin blower GSX in a Lucas oil badged trailer, the manifold looked like a modified dual quad offenhauser with an adapter. Look at the picture and see if this may be the case.
Can't help you on any of this. Really interested in how you can get that under the hood because I cannot even get a good flowing carb hat under the hood. Best of luck with this.
I already dropped the cross member 3 inches and fit a Cummins. The height of the Cummins is very close to what I'm measuring up for the 455 with the blower, it'll be close though.
In the 80’s/early 90’s there was a blown blue 70 gs from Chicago that was owned and built by the Chicago land president of the gsca. I may have some pics of that car in the archives. Was a pretty nice custom / show car from what I recall. Showed it in the annual world of wheels show in St. Louis
I have built a couple of them, but both have been 8-71's from Don Hampton.. The manifolds are converted Offenhouser unit, I think Don starts out with the dual quad.. I have one here, might have to have a peek at it. I am not sure if the B/M units bolt to the same footprint. I am sure you will have to build your own manifold. JW
I've seen pics of that manifold. The 174 does use a much smaller case, so my plan is to do a similar mod to a single 4 Offy and make it as low as possible. Thanks Brent
