I have a Rover GEMS block with 4.6 rolling assembly I’m planning to put into my Series Land Rover, Edelbrock makes an intake for the Rover V8:

And you can bolt this too it...

!!! UNKNOWN CONTENT TYPE !!!

Sooooo... yeah, am I insane? I feel like this has bad idea written all over it, but in a really good way...

Edit: It would be bolted to an NP435 and Salisbury axles.

Doing what for ignition, you filthy-GEMS-block-and-no-dizzy-drive degenerate?

Why not keep the factory port injection and run megasquirt, Holley, or some other aftermarket EFI ? I feel like you’re going 2 steps back then one step forward.

Not a bad idea at all. Why do you think it might be a bad idea?  

It’s going to increase power, drivability, and mileage vs. a carb setup. Though it sounds like you still need to figure out ignition.

Dunno if kinja but I linked the Holley EFI

how will the flow match with your new displacement? seems like this is optimized for the 3.5

I’m thinking a Mallory Distributor system.

I meant a port injected EFI with some sort of distributor- less ignition.

Everything I’ve read up to this point seems to say it handles the 4.6 displacement fine. I have to do a deep dive to find the actual math it seems.

looks like its flowed for a 600-800 cfm carb, which would be overkill for 280 cubes so you should be good there.

Ah, okay. I don’t want to deal with coil packs I guess.

As someone who used to have a Series with a 3.5 V8 stroked out to 4.4 on twin Stromberg carbies ...this is an excellent idea. Mine also had Genie headers into a 2.5" exhaust. The stock driveline (4 spd manual into rear Salisbury) handled it fine.

My greatest concern in your case is with respect to the brakes and steering...

The axles I have are converted to disks already and I’m putting the Series 3 brake booster in. Steering box is getting a good work through so it’s tight and not loose.

I’m planning to set a Rover V8 on a project up with a distributor, but also port injection. Kind of the opposite of Bloody.

In that case...brakes are sorted. However, you may want to consider a power steering conversion. It’s not essential but it’ll make life much easier when under actual power. Mine didn’t have it and both under and oversteer w ere things. However, I did find a return to centre steering damper very useful.

So, like the stock 3.9 setup?

Diesel swap?

Good point on the over/understeer, my dad has fitted a Land Cruiser power steering box to his 109. It sits on the outside of the chassis but it fits.

My dad is working on putting a 1.9 VW diesel in his 109, I’ll see how he gets along with that. Difference being I have a good V8 short block and new heads vs finding a whole new engine. If I can’t find a way to fit the V8 in my S eries without having to move the radiator I might go that direction.

What computer are you going to use or will it be all mechanical injection?

I thought about a hilborn style constant displacement pump  for a minute, but nah - going to be the fuel only variant megasquirt, probably. '63 car with a reconstituted engine from multiple sources, epa certification or lack thereof can suck it.

Kind of, except not with the stock computer - with a megasquirt . Also not stock injection, because I have motorcycle throttle bodies x 8.

At the time, there was a mob in the UK doing PAS conversion kits for Series vehicles. Not dissimilar to this...

Did you make a custom intake for that? That sounds nuts!

RamblinRover Luxury-Yacht > razorbeamteam 10/24/2019 at 17:48

I haven’t made the intake yet, but as it happens Honda CBR600RR throttle bodies attach onto round tubing with rubber slip collars, so the only tricky part is that I can’t use flat plate for the interface with the head without some building up where the bolts go. That and putting a boss on them to fit a thermostat housing, one per side.

I do have the ability to weld aluminum and I have a mill, so... whenever I get around to it.
