a 5.7 wil go straight in google 5.7 catera there is a mopar firm in i think its Illinois that will convert a catera to a 5.7 chevvy they even sell kits on eBay the last time i looked you could buy a 5.7 mounting kit and ecu interface kit for $700 which isnt bad but a crate hemi 5.7 is around the $10k mark so that put me off!

it does look like a p6 engine now i have seen the pix i agree i bet it sounds marvelous though

Mate of mine has a Cobra (Dax Tojeiro) with 3.5 RV8 (I believe it had a hurricane cam, but otherwise bog standard). He had a pair of side pipes made with slightly less than the usual standard of sound deadening. Went to Le Mans with him and it was the best sounding car I saw all weekend. Even the pukka Cobras with 427s and the like in them didn't sound a patch on his. The Rover V8 really does sound fantastic.  

I think he was getting 30 MPG too. Doubt they were getting half that but he managed to avoid any TLGPs.

25? I never got more that 18 out of a V8,was an auto, as all good cars should be.

Till you have had one.

the rover v8 in p6 and sd1 cars is american engine it is a (excuse spelling) beuwick engine ,my brother has a triumph tr7 with tr8 v8 conversion,has rover engine from sd1,but the car has had 17 thousand pounds restore work done to it,engine sounds well nice,with the header pipes and straight through stainlees steel exhaust,had allsorts done to engine,he had it tested and is throwing out 290 bhp,not bad for a car that weighs next to nothing 8-) 8-) 8-)

Yep. Rover V8 started out as the Buick 215 in 1960 IIRC. Bought by Rover in about '63 when it wasn't a total success in the US.

For such an old design it doesn't do too badly really.

Saw a lovely P5B Coupe yersterday.

Lets get this right, it was bought by Rover who then screwed the head design up and made the headgaskets prone to failure by fitting extra bolts (not fixed until 1994!).

And these days its still a pretty poor design thanks to the poor flowing heads (and wildcat replacements require a house remortgage!).

To get 280Bhp from a 3.5 requires masses of work and expense.........it would be cheaper to get a 4.8 and do a lighter tune.

The fella that did the work on my TR8 said the 3.9 was the best engine to go for as it revs easier, don't know how true that is, but it was very quick

Yes, that was a typical "Well, just chuck a couple of extra bolts on" BL bodgery. From the company who only rushed out new engine designs when the tooling to make the old one wore out.

They dont rev easier, thats not a fact in fact they tend to be poorer at revving due to the increased piston/rod assembly mass.

The only difference between the 3500 and 3950 is the bore, the 3500 is 89mm and the 3950 is 94mm (from memory). The one advantage you do get is that there is slightly less shielding by the bores on the valves (questionable that this is the restriction when you look at the head design!) but, the 94mm bored blocks are also known to drop liners......which is not good at all.

There are then a few other derivatives including the later (94 onwards) 4.0 (actualy a 3950!) and 4.6 (a stroked 3950) which had cross bolts on the block and the extra row of head bolts removed plus a much improved crank driven oil pump all developed as part of the failed iceburg diesel project.

TVR then took the 4.6 out to 5.0 for the griffith and some have bored and stroked it to a whopping 5.4!

Thing is that even a heavily modified 5.2 with big valve heads will only make 330-380 bhp at best.........all for about 6500+vat just for the engine (no injection setup!)

this is my little bro's v8 tr7 sorry no engine shot's though,they where takem at a show a couple of weeks ago 8-) 8-) 8-)




and his is injection aswell to add

BUT the LS1 5.7 V8 as found in the Monaro ONLY produces 350bhp, and starts at £4500 plus VAT plus all the ancillaries, so the ex-rover V8 in whatever guise (320bhp in TVR 5ltr form) is actually quite cheap, and RPi engineering aren't that cheap hence why they are asking over £6k for their 5.2!!(yep i read the same web page as you  )

Yes but, that is a new untuned engine, not something stretched to the point of breaking and heavily modified and no longer supported.

You could get a more basic small block for much less and throw a supercharger at it or get an LS1 from a breaker......all cheaper and better options than the very dated RV8.

Further more, the ancillaries for the mass produced small blocks and tuning options are very cheap and well proven.

The RV8 is not a good choice for power, its ideal for lazy lugging in a Range Rover but not for other applications.
