Instead of a V-8, please consider a GM 60 degree V-6. Narrower than any V-8 and comes in 2.8, 3.1 and 3.4 liter versions. The 3.4 liter is fuel injected and therefore needs a computer - that's why I chose the 3.1 liter version. With a Holley manifold and four barrel it is fairly peppy, but idles like a watch.

Hi Jim , one of the biggest problem I had and its still ongoing, was changing the diff from the original 3.9:1 to the 3.07:1 needed for the V8. I returned the 1st at the end of last year because it whined on overrun. The new one is just noisy all the time and will be going back at the end of the summer. All the rear axle experts I have spoken to say the quality of the modern gears is not as good as the original and no one will guarantee that they will be quiet. I hope this doesn't put you off to much. It might be worth looking for a alternative with a similar ratio's and modify to fit.Good LuckSteve Davis

Here I go again - I suggest you try using a GM rear axle, regular or Posi-Traction, as they are definitely QUIET. Yes, you will need to have both the housing and the shafts shortened by some one who knows what they are doing. My MGA has a GM 3.43 Posi-Traction rear axle that mated well, with the 3.1 GM V-6 for performance and with the GM 4L60 automatic trans for performance and economy. I wanted a license plate that said "AGMMGA" but it wasn't available.

Hi, Sorry, most of this Journal is retrospective, only just found the journal section, so just putting together the story so far, 'tis going to be a Land rover discovery 3.9Rear axle choice is still up in the air. Probably going to leave the standard 3.9 diff in until I can figure a way to choose a plentiful axle that won't be too hard to narrow.

The original 3.9 with work fine for the time being, but the engine will rev more through the gears.
