MEANXBCOUPE engine build up.

[MEANXBCOUPE]

Hello people!
Welcome to my new thread.

I thought that I'd do a thread to cover the build up of the new motor for my '74 XB Coupe. First I'd like to thank Col and Dave for helping with the positioning of the thread.
I dont frequent the Clevo site too much, where it really should have been before the openning of this new build up section and prefered this thread to be in the Coupe Club section any ways. Got a soft spot for the club you see.
Thanks guys........


OK, so a few people may have seen my car in Street Machine presents, Australias toughest Fords.

Cover car, yeah.


The photos and artical were taken back in June last year.
I attended motorex in July, about 2 weeks before the issue hit news stands.
A few weeks later I attended the NSW All Ford Day at Warick Farm racecourse, but, with a dark secret..... (play suspencefull music).

The week previous to the All ford day, The car was back at my workshop for a few adjustments, panel gap wise. It was a Friday night and a barby wasput on at work for the boys, we were packing away customer cars for the night. Mine was the last put away, so a burnout was in order!. Long story-short. Im now bulding a new motor after I struck water.

Truth be known, The car was sounding off before the " testing" started, maybe a small ignition issue or something, so ive got only myself to blame.

Motor before big bang



So now you know, It had a blown motor in more ways than one!! That explains the tilt tray.


Anyways, Im going to follow the progress of the new motor build up and post any updates here for your enjoyment. I dont pretend to be a gun engine builder but over the last 18 years Ive allways done my own work. This is the first catastrophic failure to date. Yes ive broken down and stuff like this but never lost a motor before.
That was probley my biggest worry before the motor was pulled down, did I screw up??? What did I forget to do???. Now I know.

The car came back to my house after All Ford Day, where it has remained since.

Dont get the idea Ive slacked off and waited 9 months to fix it, Ive been busy you see. Early September seen the arrival of my first born, Lachlan, and gotta say, Both Tracey and I have not stopped (or slept) since. The coupe has taken a back seat for a short time till we settle a bit with Lochie.

OK, nuff of the dribble. Motor got pulled from the car in late December.

Empty bay. :



Here we see an engine block, You may notice a hole, this is bad, bores should not have holes!!!. Check out the wall thickness. Measured in at 0.032", good ad for sonic testing. FYI other side of bore measured at 0.250", Core shift.



Number one cylinder.

Here is a picture of the crank and rod!


And piston and rod!



Basically, too little wall thickness plus 0.030" bore plus 10 pound boost = a total loss of motor.

I kept the following parts.
Rocker covers
Manifold
Blower
Carbys
Water pump
Pulleys
Dizzy ( although its bent the shaft its custom made so I'll need to fix it.)
Sump ( 7 holes in total, kept it for the above reason, custom)

The block is stuffed ( and now land fill) Allready 030" over, no point sleaving it. Number dont match anyway and isn't a GT block
Crank is bent, wouldnt rotate in the block.
One piston shot, it "fell" into the hole in the bore, jamming it snapping off the rod.
Rods, junk.
Cam, broken in thre places due to the broken bit of rod beating the crap out of it.
Dizzy, bent drive shaft due to the cam twisting in the block putting pressure on the shaft, I'll fix it as said.
Heads, not too bad, but a few bent valves, we go into this latter.

Any way thats it for now.
Hope you follow the journey!!!
Cheers Gary.
