Ford Y-Block Aluminum Head Testing Part I

The much awaited for Mummert aluminum cylinder heads for the 292/312 Ford Y-Block engines are now a reality and have been tested on the DTS engine dynamometer. With no modifications these new heads were found to be worth a solid 56 horsepower increase over the stock “G’ heads with only the heads being swapped out on the test 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.

Rocker Arm Geometry

Rocker arm geometry is an area that’s very often overlooked when modifying an engine for increased power output and/or efficiency. Besides the obvious advantage of reducing valve stem and guide wear by minimizing the “scrubbing” action that can take place when the rocker arm geometry is optimized, the maximum or advertised lift at the valve for a given camshaft profile can also be obtained.

Blueprinting for an eight second Y-Block

Like any engine that’s in its planning stages, particular care must be paid to that engines intended use in  order to select the correct parts and maintain those clearances that would be considered optimal for that combination.  In the case of the blown engine for Randy Gummelt’s rear engine dragster, I’ve already covered some of the parts selection as well as the main support girdle construction in previous articles.  At this point, I’ll cover in more detail some of the specific clearances and specialized machine work that was required to make Randy’s engine a reality.
