Which V8 engine?

I'm trying to weigh up the pros and cons of two different Rover V8 based long engine options for my project.

OPTION 1
5.0 TVR engine (standard) with low mileage from a Griffith.

OPTION 2
New 4.6 'built' engine. Something like a Dominator 4.6 from V8 Developments...

Option 1 will probably end up being a bit cheaper. Its going in a fairly lightweight (1000kg - 1250kg) street car, and the induction set up is yet to be decided.

I wonder if anyone has some advise on what would be the better choice.

Hi
or for a little less than the 4.6 you could have one of these crate engines ie you just connect the power and exhaust system. . .

Oh and that is 430 real horsepower not the little ones used to rate rover engines.

It's a nice idea Mike and I've given this (and the Ford Coyote V8 ) some serious thought, but my chassis and drive train are already set up for the Rover V8. Id need to change the gearbox, rear axle, engine mounts, exhaust manifolds, throttle pedal...

If it's a sporty vehicle, do you really want the low down grunt of the long stoke engines over the freer revving characteristics of the short stoke ones like the 3.5 and 3.9?

Yes!

To be honest, the Griffith 500 I have is awesome and throws one hard back in ones seat and I can spin the rear wheels in the dry on acceleration. Mind you my car is 775kg (mass in running order).

On the other hand, it is a real and gentle cruiser which is the mode I'm usually in except for the opportunity (read fun) of putting the foot down when safe to do so.

You wouldnt have to change everything.

The crates come with factory manifolds, and they're a pretty snug fit to the block so should fit a lot of cars.

But Roadcraft's prices are plus VAT, and yes there would be other work to get it running, including wiring and ecu etc unless you opted for a carb install.

Realistically you'd be into £7-8k for a running setup via a new crate....and yes things like gearbox may also need uprating.

V8D's Dominator 4.6 looks good. Wonder what cfm these heads flow? TVR 5.0s can be a bit fussy and the 4.5 went almost as good.

Turner Engineering also do a top hat 4.6 with gasflowed heads and a H180 cam for a decent price.
