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.

Oil Viscosity and Its Effect On Engine Power
It’s pretty well known that engine oil with a higher rated viscosity tends to rob power from the flywheel end of the engine. It’s this mentality that has the new car manufacturers using lighter weight engine oils in which to increase the fuel efficiency of their engines as well as pick up some additional power.

Intake Manifold Plenum Slots
In dyno testing the different intake manifolds on various engines, it’s found that the intake runner and plenum designs are main players in determining what the power curve for a particular engine combination will look like.
Y-Block Ford – Dual Quad Testing on Aluminum Heads – Part II
With the iron 113 heads on the dyno mule, the Edelbrock #257 2X4 intake that had been ported by Joe Craine did exceed those numbers generated by the stock Mummert intake and single four barrel carb combination. Now it was time to install the aluminum heads on the 312+ dyno mule and see how those same dual quad manifolds would fare.

Y-Block Ford – Dual Quad Testing on Iron Heads – Part I
With the resurgence of the Ford Y engine making a comeback as a viable replacement power plant for more than just mid-Fifties Fords, there is suddenly a demand for both modern performance and old school looks being in the same package. Continue reading “Y-Block Ford – Dual Quad Testing on Iron Heads – Part I”
Cylinder Head Milling for a 1cc Reduction
In the course of milling cylinder heads for a specific decrease in combustion chamber volume, it becomes necessary to know exactly how much a cylinder head must be milled for a 1cc (cubic centimeter) reduction. Continue reading “Cylinder Head Milling for a 1cc Reduction”
Milling Heads for a Horsepower Gain
Over the years I have heard a variety of numbers from 2% to 10% for what a point in compression ratio is worth in regards to horsepower output. The ten percent value obviously sounded a bit exaggerated while the two percent value sounded a bit on the small side. Continue reading “Milling Heads for a Horsepower Gain”
Camshaft Balancing
I’ve always said, “If it spins, then it likely needs balancing”. When going for that last bit of detail in blueprinting an engine, then camshaft balancing comes into play. How much is it worth you ask? Continue reading “Camshaft Balancing”
Camshaft and Lifter Failure Causes
Here is a list of items that are contributing factors for a flat tappet camshaft (new or otherwise) and/or lifters to experience a premature failure. Continue reading “Camshaft and Lifter Failure Causes”
A Tale Of Two 330 Inch Y-Blocks
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”
