Hi-Volume Oil Pump For the Y

Although I normally wouldn’t advocate a high volume oil pump for a run of the mill Y block (1954-1964 Ford 239, 256. 272, 292, 312), I did run into a situation where the use of one would at least be a temporary fix until a new engine could be built to replace the current one.  Continue reading “Hi-Volume Oil Pump For the Y”

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”

Y-Block Ford – 3X2 Intake Testing

What started out as a simple dyno test to evaluate the performance differences between the small and large port Edelbrock three deuce intake manifolds ended up turning into a full blown test where seven different 3X2 intakes were compared on an engine in a back to back dyno test.  The other intake manifolds being added to this test included three different intakes wearing the Edmunds brand, a Weiand intake and an Offenhauser intake.

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”

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”

Carburetor Spacer Testing

While Glen Henderson’s 337” Y was on the dyno, a variety of two inch tall carburetor spacers were tested.  The results were more than interesting and re-enforces why different combinations of parts are tested.  The baseline test for this was no spacer and then there were three different styles of 2” tall spacers put into place and evaluated.
