Preparing a 375 inch Y-Block Ford for the 2009 EMC Competition.

By the time this is published, the 2009 Engine Masters Challenge (EMC) will be history and the final results very likely posted all over the internet.  Because this is being written as the engine is still being tested and before the competition takes place, I’ll do a followup article on the actual competition and what took place there.  But in the meantime, here’s the short version of what was involved to get a Ford Y-Block engine readied for the EMC competition.

Neoprene Rear Seal Installation for the Y (and others)

  Y-Blocks would appear to have garnered a reputation for marking their territory when sitting still and so one of the most often asked questions is how to stop those pesky oil leaks at the rear of the engine.  Because most of these are in the area of the rear main oil seal, I’ll go through the steps I take to insure that the back end of the engine is buttoned up securely during the rebuild thereby minimizing any oil leaks from this area.  Because I use the rubber or neoprene rear main seals exclusively in those Y buildups that I do, I’ll only go into detail on using these seals and not the ‘rope’ style of seal.  While neoprene seals are available from several gasket manufacturers for the 272/292 engines, only Best Gasket offers a made to fit neoprene rear seal for the larger mained 312 engine.

Engine Masters Challenge Y-Block Entry for 2007

The idea for entering a Y into Popular Hot Rodding’s Engine Masters Challenge competition was prompted by discussions on the Y-Blocks Forever website.  I sent off the application form and was ultimately assigned the alternate #15 position which meant as the participants within the first thirty competitors either dropped out or failed to qualify then the alternates would be moved up the list.  I realized early on that actually making the competition from alternate #15 was a very slim chance based on what I had seen in previous year’s competitions but would give it a go.  There were some heavy hitters actually placed after myself in the alternate list so that did give some consolation.

Altering Rocker Arm Ratio By Varying The Length Of The Pushrods

Fig A.A unique feature with the shaft mounted rocker arms such as those found on the Y-Block (as well as the FE, MEL,  and LYB) Ford engines is that the solid lifter or lash adjusting versions can be measurably variable in the rocker arm ratio depending upon where the lash adjusting screw is positioned within its range of travel.
