Although there were a multitude of Ford 272 Y-Block engines used in both cars and trucks, they are pretty much disregarded as the basis for a high performance build and for that matter, as a replacement engine when a 292 or 312 is available instead. While building a high performance 272 Y has been on the ‘like to do’ list for awhile, it has been a hard sell when the larger Y engines simply make those higher power numbers much easier to come by. That all changed recently when a customer wanted to use the original 272 block from their 1956 Ford pickup as the basis for a new engine in that same truck. In this instance, they wanted modern performance upgrades applied to it including a pair of Mummert aluminum heads.
I recently had the opportunity to assemble a pair of Ford Y-Block engines that were very similar to each other and then dyno test each. Both engines had the same bore and stroke, the same camshaft grind, and the final static compression ratio (SCR) on each was very similar. Continue reading “A Tale Of Two 330 Inch Y-Blocks”
After submitting the EMC entry form for 2010 and then the list of competitors was published, I found that I was again on the alternate list. Continue reading “The 2010 EMC Y-Block Entry Breaks The 500HP Mark (on pump gas)!!”
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.
