I trial fitted one of the new rear rims today. It sit out another 2" from the current wheels.

I will definitely have to fit the new fenders.

I removed the engine and gearbox today. It makes it a simple task to remove as one piece using an engine tilter

I am getting the engine ready to pack in a crate. A mate has purchased it for his 57 Chev.

Next job is to get rid of all the vacuum hoses, heater hoses and hide as much of the wiring as possible.

For the Legend 700 gearbox I decided to use a reproduction 621 GM bellhousing. The casting is about double the thickness of my original 621 housing.
I checked the bellhousing to crankshaft alignment. The total indicated runout came out at 0.007" or a misalignment of 0.0035".
5 thou is the maximum misalignment before offset dowels are required.

To keep with the blue theme of the car I had the red anodising stripped from the MSD crank trigger bracket and done in blue.
The throttle body was originally anodised a pale purple which I also had stripped. I then polished this.

But the difference is Brad.

Your "far from" is measured in 1000th of an inch while others are in inches :-)

It's taking a lot of work and $ but it's slowly getting how I want it.

I am back at work now for another week

When I get back home I'll start pulling the vacuum system out and fit the electric headlight motors.
I am also going to replace the noisy external electric fuel pump with a aeromotive phantom intank set-up. I've read nothing but good reviews about this conversion. I'll post pictures when I do it.

I managed to make a bit more progress today.

I machined 6mm off the length of harmonic balancer boss. This was to compensate for the thickness of the crank trigger wheel and keep the crank pulley inline with the other pulleys.
Its puts the harmonic balancer closer to the engine but doesn't effect the engine balance or the timing cover seal. Its put the timing pointer away from the balancer timing marks but its no problems as I have marked TDC on the trigger wheel and have the pickup set at a 50 degree BTDC crank reference angle. The ECU handles the ignition timing from this reference.

I also fitted an Aeromotive Phantom 340 intank fuel pump to a new tank. This conversion very easy to do and only took about an hour. Basically it consist of finding a suitable spot on the deepest part of the tank. Hole sawing a 3.25" hole and using the drilling jig to drill ten mounting holes. A retaining ring with ten studs is then fitted in the tank followed by a foam and rubber baffle. A seal is fitted on the top side of the tank followed by the pump assembly. There are three -6 o-ring ports on the top plate, outlet, return and vent.
On my previous setup I had a sump welded in the bottom of the tank. This then feed an external pump. I rubber mounted the pump but this was still very noisy.

The old system.

And the New.

Top job on fitting that fuel pump Brad looks like a factory fit

where did you end up getting the new fuel tank from ?

Jethro

craigh · « **Reply #376 on:** July 15, 2014, 07:39:47 PM »

Thats looks great Brad.

Why did you need to change tanks, pump etc, just noise or ...as I thought you were keeping the same FI system or was there not enough capacity for the new motor ?

I got the tank from Ecklers, I usually don't buy from them as I have had problems in the past.
This time they had the best shipping quote and I had no dramas with them.

Thanks Craig,
I never liked the inline external pump setup. At the time it was an external pump or try fabricate an intank setup. The external was easier. If this conversion kit was available previously I would have used that.
The noise was also a factor.
Both system have the capacity, this new pump is advertised to be good for 825 horsepower EFI naturally aspirated.
The only thing I am going to do to boost capacity of the FI system is replace the 42lb injectors with a set of 60lb injectors.
I was going to use my existing tank (which is also new) but decided as I had already modified it with a sump just to get a new one. Later on I might put it in the for sale section with the external pump.

Everything on your car looks neat and surgically clean. I love it.

Have you thought about using E85 at all? IIRC you are out in the sticks, so you probably can't get it close to home anyway, but if you allow for it now at least you may have the option later. Stuff like fuel line and filter sock compatibility. When I get mine back on the road and fuel inject it, I'll be investing in a flex fuel sensor so I can run both, but I have a servo 3 km away that sells it.
