The car was built years ago and came to me robbed of parts, needs welding, but will be a nice car once finished i reacon, its still running on the steering box front end but has gt struts etc. I am looking to put in a narrowed 2.8 special rear axle, i have been offered a TVR 4.0 motor in good cond but what should i look out for regarding probs with it?, this isn,t the first car i ve built like this i also have a yb powered 105e, but any comments will be greatly appreciated, oh and wiil post some pics soon, cheers, Simon.

Bigger is allways better, but do not think tuning a RV8 is a cheap exercise, its deffo not!!!!
All blocks share the same bore except the 3.5. so engine capacity is not a problem, even using a later 4.6 crank is feasable if you want to get the crank machined, Real steel offer stroker cranks,
For me as a starter point, I would be looking at a 3.9, ARP studs top and bottom, arp rod bolts and a decent set of pistons, with this combo the engine is safe to at least 7k, you can get away with stock pistons and I know of a couple of people who do, Heads are the key to HP on the rover, and to get good HP you need good heads, especially in the exhaust area, personally I like a lot of compression Im runnig 14.1 static, but with my cam it works out about 12.1 dynamic,

Does that include the new coscast blocks?CastleMGBV8 wrote:Simon.
Welcome, just to let you know the TVR 4.0 engine is actually a rover 3.9
so not cross bolted mains like the Rover 4.0 and with other differences with the crank rods and pistons.
Also the Rover 4.0 had the worst grade of blocks and are prone to problems. as are the 4.6 engines.
Kevin.
I have a 4L cross bolted coscast engine and I was led to believe that it was very good

The Coscast blocks are of a higher quality. Whether that means any better is anyone's guess.
Simon, welcome to the mad house. First piece of advice is watch out for Cortina owners......they all want a zillion bhp at 12,000rpm
Second piece of advice is watch out for Capri owners.....they to all want a zillion bhp at 12,000rpm
Third piece of advice is dont listen to Range Rover owners........especially the ones that have abandoned the Rover cause for a Buick 455
Oh and by the way did I mention I just happen to have a spare one
Honestly though in respect of your question you need to decide how deep your pockets are because the Rover V8 needs very deep pockets if you are going to get any serious power out of it.
My advice would be to find a nice 3.9 and start with that. Most of us started with a base engine and over the years we've acquired the bits and knowledge to push the limits a bit.
All the best
