Ford small block "302".
Discussion
Probably right.
I have a tweaked 4.6 RV8 in my TVR Chimaera at the moment.
I love track days and it is on those that the old 4.6, even though it is pushing out 320ish Brake gets a bit out classed on the faster circuits.
Ideally, close to 400 brake at the rear wheels would be epic, is the realistically achievable?
The ford engine with the correct spec sounds like it's up to the job, stronger, slightly smaller, bell housing available to fit my T5 box and lots of tuning stuff out there.
Like a lot of guys, £ isn't endless and I need to seriously keep that in mind.
From my very limited knowledge there is a lot of variations and a lot to learn out there.
I could and probably will build an engine to suit eventually although if the right engine with a bit of history came along, that would be the far easier/quicker option!

I don't know about the niceties of it but an LS1/2/6/3 is a smaller and more compact engine than the Ford and crate engines are cheaper. I know one guy here has a TVR with one in it (jellison).
Also when you say a 302, you're talking about the old cast iron engine (presumably) that was replaced by the all-alloy 4.6 2v back in the 90s and became the 3v in 2004 with the advent of the 2005MY Mustang GT (with 300hp as standard). That's obviously a 281 but has many supercharger options. The modern 302 in the new Mustang is going to be very expensive.
Would it not be easier to supercharge what you already have?

I was thinking about the older engine on the basis of cost.Unfortunately, I can't really afford to go LS, (I think) I really don't know the costs involved.
The ford option sounds attractive as there wouldn't be any gearbox issues as far as mateing is concerned.
S/C? Don't know, I'm sure it would tick the power box, is the engine strong enough for sustained track use, probably.
Again, how much for a S/C kit + add a full MS or Emerald type kit, is that a better option?
to be honest a 4.6 RV8 doing 300 bhp is mild, I would keep what you ahve and spend a few ££ and clear the 400 mark with out any engine swaps
as previously stated cart ford lumps are not light on the scales so you may get the bhp but will the handeling be off ?
track cars are not always about pure power but how the car goes especialy round the bends
just my 2p worth

400 bhp rover v8 will cost a arm and a leg, be unreliable and a nightmare on roadUnless I've been doing it all wrong
I got
4.6 top hat block, high comp pistons, ported heads with large valves, large inlet, large mech cam etc if im very lucky I will be at 330-350hp
With out going throttle bodies for another £3k+ to gain 20hp it's not going to get much faster with out building a full out race motor and that wont be usable on the road
Where as the Ford lump, there's a unlimited after market parts supply out there to make a piss easy 450bhp with road manners and half decent mpg in a 1 ton car, it mates up to the existing gearbox its a no brainier if you ask me,
As for the weight? its going to be at worst 20kg's more, its no different than having a fat bloke driving vs skinny guy
The Chevy is better and cheaper
But it's wider which will stop routing the exhausts down the side, so you can add £1500+ for exhaust
Also going to have issues bolting it on to existing box,bellhousing clutch etc
Where as the 302 bolts straight on the Tvr box
Making it at least £3k cheaper to do with the ford

True, but put ally heads on it and a scattershield bellhousing and you are well on your way.... http://store.prestoliteperformance.com/gm-sb-to-un...
