Discovery 3.9 v8 - rebuilds, reliability, options….

You can have a Rover V8 rebuilt to any specification you like. They were installed in TVRs with displacements of 5.0L and well over 300hp (I dont remember the numbers exactly). The standard carby 3.5 came as mild as 135hp, and 155 with EFI, or 190hp in TVR 350i flavour. The 3.9 made 275hp in the TVR 390se, but only 182hp in Land Rovers.
If youre starting with a dead engine thats sat around for years, and everything needs refurbishing or replacing, then you "may as well" build it exactly to your needs/taste. If youve got a decent engine which already runs decently, youll spend a lot of money to improve what is already vastly superior to whatever old diesel lump youre removing.
Pretty sure the rv8 in the stage 1 was detuned to 90hp 🤯🤔
 
If you worried about over-heating, I cannot recommend oil coolers enough. Worked great, even at 50° C, I kidd you not, ambient temp, engine never got even close to over-heating despite running very lean due to boiling carbs. Easy to install as well.
 
Oh yes, I sprinkled some water on them, evaporated immediately. The engine was perfectly fine so. I think the carbs evaporated more fuel that day than the engine burned. Luckily, fuel was, for us not so much for the locals, dirt cheap. Only time I had in my life, that the outside air will driving was hotter than the air inside the car. Drank almost 7 liters of water, did have to go pee once. Now I know why the forst Paris-Dakkar RRCs had fuel injection instead of carbs.

It was a fun trip, have to do it again some day! But maybe a little earlier, like February or around Easter instead of late May.
