Dont bother going GM unless you have lots of money and a lot of time
Its a lot easier to stroke the Rover V8 out to 5.0 link above

And you dont need an engineers approval cause its the factory engine

Yea don't do it, cause I've never tried it

Downfall is, no adaptor for the auto to transfer case, can mount the 5L infront of the ZF, it'll handle it stock, but if you plan on upping the HP after that, it won't take to well and are big bucks to build tough

They are an easy engine to use in a conversion

I'd suggest 6L 4L80E

Brilliant combo, if you can afford it the 6L80E would be more brillianter

What did the 4L80E come with? Was that the 6 litre tranny or an HSV part etc?

The 4L80E you need comes from a Suburban . Im doing the same , sticking in a Holden V8 engine , The rover 5 litre is gutless pile of crap compared to the Holden and by the time you have built it will cost more than the Holden V8 . and last a quarter of the time/Kilometers . THe only way you get any sort of Half decent power out of any rover V8 is to supercharge/turbo it . As has been stated forget the T700/4L60E they simply dont fit . (easily)

Are you talking about the Holden 4.2 or 5 litre V8? From what I have read, both and especially the former were regarded as being rubbish engines. Poorly designed and in need of a rebuild after 100,000 miles or less. There was also a problem with the 5.7 litre Gen III where piston slap resulted in large numbers of engines requiring a rebuild while under warranty.

A well maintained Rover V8 will run for more than 30 years so add another and that will drive you till your driver's license is revoked.
