Dyno is booked, it will be chassis.

No entry yet, got some family issues at the moment so may not get there, I will know by the end of next week.

I have about 120 thou on the inlet with 60 thou radial clearance.The exhaust has about 260 thou and does not register with the clay.

It worried me a little but after reading copius amounts of data it seems I have nothing to worry about in this regard.

The consensus is that checking with soft and light checker springs as aposed to the normal springs, will give you an extra 30 thou clearance. Apparently the resistance in the valve train, chain stretch, deformation of the push rods and flex of the rocker studs actually retards the timing when the engine is running. When the timing is retarded that gives you more PTV on the inlet and less on the exhaust, hard to measure that although !!

Love this video,

Thanks Greg,
Interesting video, amazing to see the residual energy in the spring after the valve closes!

Good luck. Hope you make it Greg.

Blacky can you see this ?

The heart is back in !!!

Few anxious moments and yes I chipped the firewall paint with a stupid brain fade !!!!

Oh well brush repair it is. Hook up all the stuff tomorrow, cant wait.

Will do Billy, a couple more days.
All the underneath is done, just radiator and exhaust plus a tidy here and there.

Greg

Hell that is pretty!

Can you see a reflection of me somewhere ?

Well the trip Echuca was tops but i returned with a couple of fixes that need to be done.

Post mortem, fuel starvation and vapour lock, not really bad but can ruin your day because of its unreliability.

What I need, a new tank that will support the proper fuel delivery system, I could stay with the XB but I want to have it pain free, is there any such thing ????

I have learnt a lot on this journey and the fuel injection is something i need to conquer personally !!

So initially we have a gravity fed pump that supplies the old style analogue controlled Holley injection, great stuff until you run low on fuel or take a nice left hand bend, all the fuel goes to the drivers side and starves the pump which in turn gets hot from no fluid cooling and vapourises the fuel into gas. Technical , you bet.
The modern aftermarket fuel pumps for injection are interesting because you can't just buy a pump based on psi output as the pumps vary in speed with voltage ups and downs so the psi is constantly changing. Most are rated via volume pumped at a certain voltage and the psi is a variable due to pipe size length and the amount of bends the fuel lines have.
I have chosen a holley sniper throttle body injection and am going to set the fuel delivery with a return system. This means the pump will create pressure and go through the throttle body and exit via a remote regulator then back to the tank, the pressure will be 60psi.
The decision i made today is to use a BA BF fraud pump (which you can get anywhere) it has outlet, return, swirl pot and non return valve to make sure the pump is always with fuel. The neat thing is the return line fills the swirl pot so fuel starvation apart from having no fuel is almost eliminated.
Next will be a modified aluminum tank with a sump for the fuel pump to sit in, not really required but will again make sure there is fuel for the pump to suck. I have also become fancy and have decided to use a holley fuel LIDAR sensor, supposed to be the best thing since sliced bread but afffordable compared to most aftermarket senders. The unit has no moving parts and because I will be modifying a areoflow tank will hopefully be an easy fix.
This has come about because here in NSW you are not allowed to send fuel back to the tank inside the boot so all the pump and connection will have to recessed into the top of it and under the floor. !!! PHEW.
Thats enough for tonight, I will post some progress pictures shortly.

Regards Greg

Old cars mate. It never ends. Certainly was a pleasure to finally see the beast, as well as you and the missus of course.
