Hi, im looking for inspiration on boosting my 57 ranchero. I have some Land Rover superchargers and was going to put them onto a low compression 292. im thinking about mounting them in the valley with intake going to top outlet of supercharger (m112 or tvs1320) to keep a low profile. anyone use either of those superchargers on a y block. im undecided if im using a carb of going fuel injected (needed if i go tvs). I'm not wanting to spend and wait a long time for a y-bloke and 4-71 as i the old jlr ones and means to make what i need.

I have used both the Cragar and YBloke intakes without using a 4-71 supercharger by just making an adapter to fit the particular supercharger that’s being used. The adapter plates are typically made from ½” thick aluminum plate.

Another approach is to use a blower manifold originally designed for a different engine family and then using cylinder head adapters that allows it to fit the Ford Y. Here’s a picture of a Ford Y I did using a SBC supercharger intake manifold.

"I'm not wanting to spend and wait a long time for a y-bloke "
Is the Y-bloke manifold currently out of stock?

Y-bloke manifolds are about as common to come across as Cragar's in us, also not a lot of up to date information without bothering the man directly. There's always the option of cutting the top off a 2 barrel intake and putting an adapter plate to mount a blower onto there but at that point its easier to just go scratch aluminum.

I've contemplated taking an Offenhauser tri-power and milling the carb risers off and welding an appropriate plate to it mount a blower. Since they aren't much good as an NA manifold, I figure its not much lost in cutting it up.
My buddy did a similar thing on his flathead, using a factory aluminum manifold.
Either way you cut it though, theres gonna have to be some sort of adapter plate made, mostly to overcome the hurdle of accommodating the fixed blower snout length to meet up to the crank, which on those factory Eaton blowers, aren't very long.

Ted, on those adapter plates pictured, are they open or do they keep the runner length continuously to the SBC manifold?

SBC runners are horizontal not vertical so wont transition well to y block in such a short space. A lot of blower manifold don't have the wall between runners since they're not worrying about runner length and velocity, also with horizontal port arent as effected if fuel sinks in the air charge where y block will lean out top and richen lower still showing decent reading on wideband.

The supercharger intake manifold adapter plates are open to each pair of runners. This helps the transition between the vertical ports in the intake to the horizontal (stacked) ports in the cylinder heads. Here are some more pictures of that same engine giving more detail.

Is there a photo of the engine rear available? I'd like to see how that coolant crossover (?) is plumbed.

No picture readily available but the radiator on the dragster was behind the engine which required the coolant lines exiting the intake manifold adapters to be routed to the rear of the engine. You can see the junction and coolant fill point in the picture at the rear of the engine where the two lines join up and the water is actually added. From there, an electric water pump circulates the coolant.

THANX! for the reply TED.
TECH obviously above my pay grade ...
