Vintage class winner: EMC attracts 600,000 views
Jon Kaase has won this year’s Amsoil Engine Masters Challenge Vintage class with a 473ci 1958 MEL (Mercury-Edsel-Lincoln) engine. Exploring the classic turf in distinctive fashion, it was not the first time Kaase had arrived with an unorthodox relic endowed with bewildering technology.
Held annually in early October at the University of Northwestern Ohio, his entry produced 770hp with torque never less than 630lb-ft during the entire scored rpm range of 3,700-6,200rpm. The engine’s peak torque was recorded at 715lb-ft. Earning a check in the sum of $13,700, it was Kaase’s seventh victory at the prestigious affair, which coincided a few days before his sixty-fifth birthday.
This year’s Vintage rules specified factory cast iron cylinder heads and prohibited welding or the application of epoxy to the ports. Also, it was stipulated that the engine block must retain its original bore spacing and original block deck angle. A further constraint for Kaase was the fact that he had to return the MEL block to its owner, Royce Brechler, in a functioning condition. Read More.
Kaase revives Ford FE
Big-block V8s packing 427 cubic inches (7 liters), FE production began in 1958 and ended in 1976. It replaced Ford’s Y-block and at the end of its reign was succeeded by the 385-series.
Competition FE engines were characterized by their remarkable record-breaking history, scoring dozens of NASCAR and drag racing triumphs and winning hundreds of races in Shelby Cobras. But in global motor sports, the FE’s reputation soared when it powered the unassailable Ford GT40s to two successive 24-hour Le Mans victories in 1966 and ’67. (Read more)
New Kaase Big Block Ford Rear Seal
New one-piece seal conceived for use on Ford 429-460 big-blocks; Boss Nine; and P51 engines
- ∇ Simple assembly; reliable service
- ∇ See installation sequence below
Without wishing to diminish the performance of any current rear main seal for the Ford 385-series engines, Jon Kaase wanted more.
“We had to go out of our way to find it,” he says. “In fact, we had to go out of the country—to England—to get the quality we were searching for.” Using the same manufacturing source as the Sprint Cup teams and following several years of testing, the seal makers produced the tooling, the prototype seals and now the production items exclusively for Kaase.
This new seal is a one-piece device that replaces the conventional two-piece arrangement. On its face there is a dot—a small indentation—that represents the exact place to cut the seal with a razor blade for installation.
Once cut, the seal can be wrapped around the crank and a daub of silicone sealer placed in the joint. Before lowering the crank into the crankcase, apply a light film of silicone to the outer perimeter surface of the seal and rotate the joint such that it is positioned in the main cap.
There are numerous causes for rear main seals that leak: insufficient lubrication at the sealing lip edge, shaft roughness, lip hardening, lip softening and so on. But what offends the racers and hot rodders most is the indignity of having to do the job twice, which is often a day wasted if the oil pan cannot be removed without raising the engine half-way out of the engine bay.
To this end Jon Kaase’s new rear main seal for 385-series big-block Fords is aimed at sealing it right first time.
Kaase Wins his 6th EMC Title
When legendary AMSOIL Engine Masters participant Jon Kaase considered the new Vintage V8 Class for the 2015 Challenge, he contemplated engine possibilities with the cold pragmatism of a serious competitor. One of the key requirements from Kaase’s perspective was the availability of an aluminum cylinder head. As Kaase explains, “An aluminum head allows almost unlimited modifications, and in an unlimited class like this year’s Vintage category, we wanted a head that can be machined and welded or modified.” Topping the Mummert heads is a custom adapter mating the heads to a tall Edelbrock small-block Chevy tunnel ram. The bottom end was built with a Bryant billet crank, Carrillo rods, and custom Diamond pistons. The result is a 400ci engine putting the squeeze on the mix at a 13.9:1 ratio. To work with the mushroom-tappet arrangement of the Ford Y-block, custom lifters were manufactured by Trend, with a Comp Cams billet flat tappet orchestrating the movement. Kaase custom-fabbed a long set of tri-Y headers and installed an MSD ignition system to light it off.
So what is the effect of all of these mods on this ancient Ford? How about numbers that would leave any builder of the latest hardware slack-jawed at the results. Torque started off strong at 526 lb-ft at the 3,000 rpm bottom of the test range, and twist only ramped up from there. Peak torque recorded measured 596 lb-ft at 4,600 rpm. On the power side, Kaase didn’t disappoint, with peak output showing 584 hp at just 5,500 rpm. That was plenty of power and torque over the rpm range to net a class-topping score.
