V12 rebuilding issues

Hello All, First post on the BB wondering if any one can help with general guidance and advice.

I have a series 3 v12 which due to a number of issues is being restored,to give a brief history,
My car was a usa model but during it's history has moved back to the UK and been converted to RHD and while registered in 72 is a 73 car/engine that has been altered and was running fine for a year or so until two of the valve seats decided to take an excursion through the engine and the torsion bars detach from the floor! the car is undergoing a full restoration to replace poor repairs and hidden problems (i'm sure wee all know about those!)

I am currently rebuilding the engine and have got most of it back together. New liners/ pistons skimmed heads new valves and seats cleaning and replacing the problem I have is that being an USA Spec car it has or to be more precise should have a lot of emissions control on it... a lot has been removed (inc the air con) in it's past but a lot was left on such as pipes from the air intake box that go nowhere and the what I assume is Exhaust Gas Recirculation pipes on the back of the carbs that are in place but appear blocked.

my intention for the car is to drive it and enjoy it I am not a stickler for absolute concourse, original parts needing to be there just to make it right , and i suppose the gist of my question (Finally I'm sure you are all glad to here) is what can I get rid of/ replace and block off to make the car more English early spec give it the power it was intended to have. Also for example with the EGR system that appears to be attached to the exhaust heat shield how should it operate, what is the consequence of removing bits.

A lot of information I'm sorry but it appears to be a bit of a mish/mash and whilst some books are very helpful there appears so many changes that finding a lot of this out is quite complicated.

Anything else please ask i have some photos from when it was dismantled but need to sort through them if they will assist.

Yours Gratefully
Lawrence

Hi Lawrence

This forum is a bit quiet sometimes.

If you don't get a meaningful reply here then I suggest you try the jag-lovers forum.

Lawrence,

Your questions are quite technical in nature and although I own a V12 E I don't have the answers, may I suggest rather than ask for advice on another forum, that you ring one of the club's highly experienced technical experts - their numbers are listed on either the E Type Forum pages in the National Magazine, or the club directory at the beginning. Personally I would try and talk to either Ken Jenkins or Dave Marks, a phone call or a direct email may be needed and you might have to be patient for a reply as both have to play catch up after their work/business issues.

They should provide a reliable answer or at least give you a good direction

Regards

Thanks for the replies guys i have been speaking to a number of people and managed to view a UK car of the right year which has given me enough information to proceed with the task. Once I have carried out the work and recorded what I have done and why! I will post it on here for other peoples future reference.

For anyone attacking this job the parts list available from the shop is invaluable.
