Is it really worth it?
Discussion
Having run-in the rebuilt engine and had an initial tuning, I took the car down to Torque Developments International at Lakeside. See this post as well - Re map in ESSEX. The improvement that they made is illustrated in this printout. There is still the matter of the secondary throttle not opening fully.
I can understand you may be disappointed - is that hub HP or flywheel calculated? If it's hub then it's none too shabby.
Personally I'd go to ACT rolling in Rayleigh - the guy in there know his carbs whereas the guys you've been to on first impressions from website look more set up for ECU mapping than traditional tuning - just perception from website.
ACT deal with a lot of american muscle and track cars - definitely worth a look.
That said if the carb isn't opening properly then that needs to be resolved before you can get a real idea of performance - that's where all the power is on 4 barrel carbs. Can't remember whether you were running Edelbrock or Holley carb - having run both on my 302 engined Cobra replica I'd go Holley every time. Either way the secondaries are vacuum so weird they're not opening - or have you got a double pumper? 600cfm should be good. It's all spring strengths and needles with Edelbrocks.
Go to someone who knows proper oldschool carbs (ACT!)
I know it'll be hard to believe bearing in mind how much I appear to be defeated by my wedge issues but I put new heads, roller rockers, weiand inlet and edlebrock on my cob and tuned it using Innovate wideband AFM. the procedure I got of the web was wiring the secondaries shut to start with, set up the primaries and then bring the seondaries back in for final WOT calibration. I must've dialed it in pretty well cos the 350 chevy boys coudn't drop me.

Scott, you are spot on. The set up at TDI appears very professional. The figures were taken at the hubs; wheels off. I thought the top hundreds was a bit weak for a 450. 220+ seems more acceptable. I am told I should get more when the second butterfly opens properly. I am going to have to get replacement Edelbrock carburretor springs from the States. Watch this space.
Hi Henry...I remember Ralph having issues with his Elderbrock carb and that was the springs and the jets that needed replacing, From new.
The jets that came with it were no good for his set up so hopefully once you get yours sorted and set up properly you should see a good power increase, Ideally you want someone who can tune the carb on a rolling road so that its set up properly, TD are ok with modern Japmap crap but not so good with carbs!.
Cheers...Ziga

Henry - I'm pretty sure Real Steel do the calibration kit which comes with various jets needles and springs. That was the kit I used to dial my one in with. Not sure how viable it is but if you can borrow a Holley and try it - I know, I know, we took my mates off his cobra and tried it - it felt much more urgent down the bottom end than the Edelebrock which always felt to me just a little "laggy" at low to mid rpm although better economy.

EDIT - yes they do see section S6/11 here http://www.realsteel.co.uk/section6.pdf

I managed to open it up this morning. It don't 'alf go. Like the proverbial clappers. Dare I say, more like my Griffith 500. 
Now I am beginning to believe it has all been worthwhile.
Hopefully, these are the graphs that you are looking far. Interpretation for us poor amateurs would be nice.

Henry I think you're going about it the right way - it's probably much better to buy a wedge that needs a little tuning, get used to driving it while the power is on the low side, then improve it. If on the other hand it was 300+ bhp when you first jumped in you'd probably be a bit scared of it! At least for a week or two... ;^)
Results from ATSpeed, which are calculated as being at the flywheel:
These two sets of figures leave me somewhat confused. I am content having spent the money that I do not wish to spend any more. I'll leave the readers to assess whether the whole rebuild over the past six years has been really worth it. Now, I will just enjoy the drive.
