'73 GS, more pics from engine redo
These are few more shots of sugery and completion, and plumbing for oil system which brought many changes. Rotating the Tilton starter in the mounting block to clear the scavange fitting just to show one. The shot of the feed line to the pump shows the red long Petersen catch screen housing, this will get the large debris should a failure occur before it gets to the pump. Also shown is the Earl's check valve to keep oil in the lines from running back into the pan to hold prime for the pump, newer versions of the billet block (TA and SRE) have the fittings at the top to help eliminate this problem. SRE's unit also has the mount for a Petersen belt pump which is really nice. This was a budjet job so I had to make the best of what I had, and there are two was to plumb the feed for the pump that will work and still hold prime when the engine is shut off. Also shown are the removable aluminum spacers for the ends of the SPX manifold to compensate for the taller set height on the bulldog heads, this method retained the stock rubber end seals, and allows removal for fitting the intake to another application not in need of having the intake sit higher.
