Here's the pressure pipe union at the rear end which the internal pipe attaches to.
And here's the rear bearing housing - showing the solid, white metaled rear main and the drilling modification to take oil to the bearing from the union shown in the previous picture. This housing is attached with four bolts, and one has been enlarged to 5/16" and drilled to feed the oil to the bearing.
Here's the other end of the internal pipe at the front of the block.
And here is the timing gear cover, also cleverly adapted to feed oil to the pressure pipe.
Has anyone ever seen anything like this on a SV engine? Could it have been a McEvoy modification? What advantage does it give over the standard arrangement - with the oil feed to the rear main coming through the crank - perhaps better pressure reaching the main as it is fed directly from pump pressure rather than what is left after the big ends have been fed? And presumably it would also serve to back-feed the crank, delivering more oil to all the big ends?
What is apparent is that someone has gone to a great deal of trouble to effect this modification, and it if wasn't McEvoy, then it is possible that someone was preparing this engine for competition. No competition record of the car has yet surfaced, but I'm keeping my eye out for any reference.
Finally, here's a shot of the cam. I haven't rebuilt a SV engine since I was at University, so I can't say whether this is a standard cam or not. But the cam lobes look extremely pointy to me. Is this standard? I would have thought that a 'hot' cam would have broad, flat-topped lobes - rather like the 12/12 M Type cam.
