New UK Builder (West Sussex)
Discussion
Good Afternoon All,
I have ordered Stages 1 & 2 and am planning to build in stages, (Work / family, commitments). I would like some help on choosing the engine. Due to emissions law in the UK, I have been told the LS engines are the ones to go for.
From www.amerspeed.com I am quite keen on the following:
LS-3 6.2L 530hp
LS-7 7.0L 575hp
Also have come across this website www.partsworldperformance.com through this forum.
Can anyone recommend which engine?
Regards
Mus

Welcome! Good to hear from another builder, there's a few of us out here now 
LS engine route is definately a good move. HOWEVER: it's well publicised that tuned LS3s and std LS7s are very, very, very, very, difficult to make pass the IVA emissions test. Many have tried and most have failed.... do a quick forum search and take heed from other's comments.
Don't make life hard for yourself, go for a standard LS3, get your reg plates, get used to the car, then add the tuning parts later.
Are yuo doing a build diary? Would be good to see another one come together

Welcome and enjoy.
Budget will be a factor when deciding on an engine and if you have only just ordered your chassis then the engine is a way off yet. The only decision at the moment is CBC, LS or something else so you can order the correct chassis.
Plenty of good build sites and lots of threads on here. Find a few owners in you area so you can talk spec over a beer while checking out completed/part built cars.

Good Afternoon,
Thank you for all the input. Yes I will be putting togeather a build diary and will be posting bits as the build goes on. Loads of info on here which is very good.
356Speedster - I see your in IT....same here 3rd Line Network Engineer. Very tedious but rewarding!!

Your MAD - totally, totally MAD to do this... Prepare to suffer wallet-rape (many times), a rapidly declining relationship with your Wife (or GF), sleepless nights tossing and turning and not being able to switch off, terrible back-pain due to bending around all the awkward bits while building, your nuts being freezed off in the cold winters while you convince yourself that you 'gotta' just do that one extra thing..., become a total freakin' bore to all your Mates whilst you ramble on about how you did this, did that, and how it is going to do a million miles an hour, become paranoid because you worry about being caught at work when you 'just take a quick peak at pistonheads to see if your question has been answered!', and become a bit disillusioned because it is taking YEARS longer to get your baby on the road, than you thought it would! ..but I promise...it will pass!Thank you for all the input.

So...a warm welcome to our particular section of the mental health clinic - we are all very nice people here..'tick', tick'..don't worry if we occasionally repeat ourselves, repeat ourselves, repeat ourselves, repeat ourselves, repeat ourselves, repeat ourselves...(SMACK!) - sorry...
...or start talking in a strange language.... Just ignore that, and you will be fine!

Soz, missed the std factory caveat, should have said if you go off-pieste you'll make life difficult for registration as many here have found 
Keith's comments are amusingly tongue in cheek, but sometimes we all feel a bit like that You'll love the challenges of a build tho'. Oh and you'll realise we're all slightly mad here too

You'll love the challenges of a build tho'. Oh and you'll realise we're all slightly mad here too Or... SBC it first..... leaving you a multitude of options and less emission hassle's.
A GM factory recon small block on a 75 based block can be had for £1200 and gives you and future owners 4.5% CO to play with whatever engine route you wish to go (actually a selling point in my opinion).. Or you could just mess around changing cams and maps every 12 months as modern test requirements become increasingly stringent.
You'll soon run up carefully managed conversion costs in labour and downtime after 4-5 MOT's.

It is well documented in this forum that there are substantial costs and substantial labour time involved to convert from SBC to LS engines.
The MOT Test emissions will always be a direct copy of the same emissions test that the vehicle was subjected to at its IVA Test, as listed on the vehicle registration document.
We have carefully planned a solution for the benefit of Ultima customers by using an engine supplier that are able to supply emission compliant LS engines in excess of 700bhp.

That depends on the initial build and careful parts/cost management Richard..The MOT Test emissions will always be a direct copy of the same emissions test that the vehicle was subjected to at its IVA Test, as listed on the vehicle registration document.

Regards to All,
In fact you could encourage this method to boost attraction in lean times..
People could get their basic car on the road for 12-15k less with a bit of application and support in this area.. leaving you to welcome them back for a complete performance upgrade package supplied and warrantied by the factory.....retaining the range of standardized products, quality and value (current or resale).
How many new builders eyes are far bigger than their wallets.... perhaps difficult to admit but Im sure a common issue.
Most businesses have to respond to lean times... am sure the factory will do their best.
Rgds to you too.
...OOOUUCH! .................Er! ...You did!
Not got Teds mit-prints on this one IMHO!
Anyway, Ted is getting very old you know....(even older than me - if you can believe such a thing!)
Think he is casting longing looks at green pastures, and pictures of caribbean beaches...
I am already making enquiries with Age concern for him! (Dayam - that was confidential!) -
...think I will go hide now...
