Factory fitted 427, there is 6 left that I know about 1-1963, 2-1964's and 3-1965's there was supposedly 120 427's put in thunderbirds but it is very hard to document this. Click Here for an article on the 427 tbird & Hi res pics of my Bird. This is going to be my weekend kruizer, we have spent 11 years so far on a ground up rebuild, its just had a bare metal respray in a custom colour. All the chrome is NOS, new or rechromed. I am changing the upholstery from the original red to black (storing all the original red stuff). I have some mint black door panels etc, just have the dash and the seats left to get. (I still want to do it cream with rosewood veneers on the door panels but will have to win lotto first!)The car has only done 58,000 original miles and the 427 was rebuilt and bored .30 over in 1972 not sure what the mileage was then but it cant of been much! I had the 427 fully rebuilt, balanced and blueprinted in 2004. New forged .30 over pistons, 427 le manns rods, stock internaly balanced steel crank (ground and polished 10/10), Weiand Alloy Intake manifold, Holley 780 cfm carb, stock 427 cam, Melling high volume oil pump, Modified oilling system, The heads are the stock Low riser 427 ones but have had a bit of work done to them and have stainless valves, ceramic coated full length headers and Mallory twin point dizy. We start it up on the floor every second month until it goes in the car. It sounds wicked with the headers and no mufflers, but the neighbours dont think so haha!Because it was rebuilt in 2004, before it goes in the car we will pull it down, do abit more to it and check that its still good. Its going to get roller rockers and a cam with a more aggresive profile, Electronic distributor, 4 bolt main kit and/or mains girdle, Electric Fuel Pump, Canton 9qt oil pan with baffles and if the budget allows, electronic fuel injection, link computer and a vortech supercharger! (Again I will probably have to win Lotto or wait until im 80 before that happens!) If it does get a blower i would look at building a gennisis alloy block and just putting the original motor aside, becasuse of its rarity I i'm not doin anything to the car that cant be returned fully to original spec.The transmission is the stock FMX but has been rebuilt, shift kitted and had a few modifications done and has a higher stall tourque converter.I'm looking at using a narrowed diff so I can get deaper dish rims on and converting the rear to 4-link and Air Bagging.Will NOT be using all in one "Shockwave" air struts from a certain company in the USA now after problems I have had with there products failling on my Fairlane (Pm me if you want to know the details). Very unhappy with there service, the product failed twice and they will not refund or repair them! Despite it being there product design at fault (I had NZ's leading mechanical engineer look at it) Because of this i will now make my own including electronicly adjustable shocks so everything can be controlled from within the car, and it will last a hell of alot longer than the aformentioned product - 1st set >100 miles 2nd 1000 miles. The other option is another system with this electronic adj shock from Japan but my only concern is if they will work with a 2000kg car as they are only designed for 1600kg cars..The huge standard brakes have been fully rebuilt, new disks up front, the calipers have been sleaved in stainless steel, all new brake lines, new master cyl and booster, Rear drums had a light skim (I will put some pictures of the rear drums up some day, you wont belive the size they look big enough to stop a truck!) I also have a wilwood adjustable brake proportioning valve in there to lock the front brakes (opps I mean set brake bias), not that it'll need that with a 450hp 427!Im not sure what wheels to put on it but will be 18" Torque Thrust 2's or Centreline Daggers.
