Okay, before you all start to get the wood together for the traditional burning, I've had my shadow for a good few years now and I simply don't want to part with it. I've got another roller so I rarely use her but I want to...

As in Houston there is pretty much absolutely no point in owning a sportscar (crap driving/ pot holes/ etc.) and the modding scene is huge here, I'm seriously thinking of rodding my old(er) rolls. I don't mean something hideous but nice wheels, good paint job (one colour, no flames!), newly trimmed interior, etc. annnnnd a new crate engine/ gearbox. The current engine is the original 30 year old unit and so drowned in ancilliaries I want to get back to a simple engine and cut down on a lot of extraneous 'stuff'. The hydraulic suspension will also have to go.

My question is this: does anyone have some information on the chassis? Is it a separate unit or unibody (I think its unibody). If its a ladder chassis I'm wandering whether I could buy a running rod chassis (they're easily bought here) with say a 454 CU Chevy and (providing the wheelbase and track fit) swap one for the other.

Anyone know of anyone else having done this before? My 'model' for what I'm thinking of is my old truck I owned for a while (1972 body on a rod chassis, 489 cu engine smile ) and the chevy bel airs restoro-mods I seem to see everywhere.

Like I say, I don't want to produce something hideous but a restoro-mod that looks stunning (as shadows always do) and sounds like thunder.

I've always wondered if it would be feasable to modify a shadow to take Arnage T running gear-those brakes would need some uprating though!I think it would be quite nice to have a mint shadow,keep it as standard looking as possible,but with 500bhp

Yeah, that's what I thought. Mint, minimal mods but something more beefy under the bonnet.

No, not quite that extreme wink

I like the idea of a full(ish) length glass roof though.

So, Mr. Green, is it a separate chassis?

I'd prefer just a mint original looking shadow with no hints what lie in the engine compartment....

I'd just like to say I think this is awesome. Do it and get started on your 'Readers Cars' thread.

There are actually a few Shadows and T types around, otherwise standard looking, but with Turbo R running gear. There are also at least a couple of MKVI's too, and not just Specials.

The Silver Shadow in 1965 was the first unibody Rolls Royce. If memory serves correctly bodies were made at Pressed Steel Fisher in Swindon then shipped to Crewe.

if you've a bad road surface surely you should be looking at smart suspension?

if not hydraulic why not air.

Thanks - I thought that might be the case. Just found a site that sells workshop manuals so I'm doing to get one to see what's involved.

I agree that some sort of decent suspension is required but I'll be going with air or similar rather than a 30 year old hydraulic system! I'm not saying I'm going to be going fast or trying to corner like its an elise but Shadows handle like big boats so getting an engine with 450+ BHP is going to need better support than currently is the case wink

We all knew that. I thought the question was as to whether the rodded RR that I posted up had a separate chassis.

You don't have to buy the workshop manual. Everything about the Silver Shadow (and other Rolls Royces) can be found on this site :

Good luck.

Superb. Thanks.


There is a place in the US that provide backbone chassis that you fit beneath unibody cars (you cut the floor out and weld the chassis in place). $8K for chassis, steering, brakes and suspension.
