Super Stock Engines
"Effective July 20, 1966, the following engines are approved for competition in the Super Stock class. These engines as installed must conform to the price limitation of $1750. It is the boat owner's responsibility to furnish to the inspector an itemized price list of parts used in his engine when it is inspected.
"These engines shall be equipped with one American-made carburetor having no more than four (4) venturis. The carburetor throttle plate shall have holes no larger than 1-11/16 inches in diameter.
"The engines approved are 
Chevrolet 327, 396, 409, 427 cu. in.; 
Ford 352, 390, 406, 427, 428 cu. in.; 
Chrysler 426 Wedge, 1966 Model 426 Hemi; Chrysler-:392, 413 cu. in.; 
Buick 425 cu.. in..; Pontiac-421 cu.. in.; and Olds 425 cu. in.
"Engines not approved are 
Lincoln 440, 460 cu. in.; 
Chrysler 442 cu. in.; 
Chrysler 1965 Model 426 Hemi."

Super Stock Rule Interpretations
"These four interpretations are announced in the Super Stock Class: 
(a) Any fuel pump (mechanical or electric) may be used to pump the gasoline; no air pressure system allowed.
(b) The use of oil coolers is optional. Their cost is not considered as part of the cost of the engine.
(c) Any cam follower may be used but cam face diameter must be STOCK dimension; no "roller" camshafts or cam followers allowed.
(d) Any valve spring, valve spring retainer, pushrod, and valve spring spacer washer may be used, regardless of manufacturer.

280 Hydro Fuel Pumps, Flywheel
The practice of using the fuel pump to pump air (instead of gasoline) to a pressurized fuel system will be considered a violation of the stock intent of the rules. The general opinion among the 280 Technical Committee members is that there is no valid reason, mechanical or otherwise, why the stock fuel delivery system should be altered.
Based on the results of a California company making rotational disintegration tests using various motor manufacturers' flywheels, there appears to be a valid reason to regard the cast iron flywheel used with the 273.5 cu. in. Valiant engine 8S a safety hazard when operating in the 6,000 rpm range. Since the only other available flywheel requires a machining modification to be practical for the 280 hydro use, it will be permissible to purchase or fabricate an aluminum-type flywheel to replace the stock part. Alloy 7075 is recommended for flywheels to be fabricated from aluminum. Minimum thickness should be .25
in. In any and all cases regarding flywheels for any 280 engine option, the flywheel (the wheel supporting the starting ring gear) must be bolted securely to the crankshaft. Any device which acts to disengage the flywheel from the crankshaft subsequent to starting the engine will be regarded as a violation of the stock intent of the rules.

280 Hydro Camshafts
The 230 cu. in. Pontiac overhead camshaft engine has been reviewed by members of the 280 Technical Committee, the Inboard Chairman, and the Racing Commission and has been accepted as a legal engine option for the 280 hydro class.
Only the basic, single-barrel carburetor version, as originally furnished by the motor manufacturer, will be accepted. Additional technical data and information, if required, can be obtained by writing to the Chairman of the 280 Technical Committee. The 280 rules will be updated to include basic engines furnished with single-barrel carburetors.

Chevrolet Replacement Camshaft
Effective as of June 3, 1965, Chevrolet substituted a physically different camshaft (Pt. #3862798, Cast #799) for the camshaft which has proven to be the best cam for the 265 cu. in. engine, namely Pt. #3728779, Cast #3728284.
Specifications are, max. lift at the valve (zero clearance), 0.3987; inlet and exhaust are open for 3000 including ramps, 2500 excluding ramps; timing degrees (from beginning of ramp), intake open 32.50 BTC, close 87.50 ABC; exhaust opens 74.50 BBC, close 45.50 ATC. The ramp has a 200 length from beginning to end on the valve opening side of the lobe and a 300 length from beginning to end on the closing side of the lobe.
This camshaft is a legal option for the 265 cu. in. Chevrolet engine. Sufficient information is not available to deternune if this is a better camshaft. Chevrolet claims the performance is the same.
 
 
 
 

3 Drivers Die at President's Cup
Ron Musson and Rex Manchester of Seattle, Wash., and Don Wilson of Palm Beach, Fla., three of the world's greatest unlimited class drivers, were killed in the President's Cup regatta on the Potomac River, Washington, D. C., June 19.
Musson, 38, was the Gold Cup winner and unlimited high point winner for the past three years. He was killed when the new Miss Bardahl nosedived and disintegrated in front of the judges' stand. She had just finished the first lap of the second heat a scant boat length behind Manchester with Notre Dame.
Attempts at artificial resuscitation failed to revive Musson after he was brought ashore by a Coast Guard patrol boat.
Two hours later, in the final heat of the race, Notre Dame hooked a sponson on the backstretch of the first lap. Wilson, with Miss Budweiser, was on the inside as the two boats raced bow to bow. Notre Dame suddenly bounced and then flipped onto the bow of Miss Budweiser.
The resounding collision shattered both boats and debris flew high in the air. Mira Slovak, driving Tahoe Miss, was the next boat behind the battling drivers. He stopped his boat, dived overboard and supported the unconscious Wilson in the water. Coast Guard patrol boats hurried Wilson and Manchester, also unconscious, to the judges' stand. Both were pronounced dead shortly after arrival at the George Washington University Hospital.
Notre Dame had won both of her heats and went into the final race leading with 800 points. Miss Budweiser was second with 700 and Tahoe Miss third with 600.
When tragedy struck for the second time, Referee Bill Newton cancelled the regatta. The race had proceeded after the first fatality in accordance with Unlimited procedures voted by the drivers.
The final results reverted to the standings at the end of heat 2-B. This made Notre Dame the winner of the President's Cup, a victory Rex Manchester had long sought.
 

REGION 4
Tragedy came to Region 4 last month with the death of three unlimited drivers during the President's Cup regatta in Washington, D. C.
Ron Musson of Seattle, Wash., was the first of the doomed trio when his boat disintegrated during the second heat of the race. Also killed in this worst series of mishaps in regatta history were Rex Manchester and Don Wilson when their boats collided in the final heat two hours later.
Competition among the limited inboards, also scheduled at the President's Cup, provided several exciting and close contests in a number of classes.
In the 150 class, Rudy's Comet, owned by Rudy Gurley of Hampton, Va., and driven by Frank Vernon of Washington, D. C., paced the field for two straight heats but not without some strong threatenings from Woody Pliescott Jr. of Cambridge, Md. in his Woody Jr. Special. Engine problems prevented Woody from completing the second heat and from competing the second day.
To the fast growing class of 225s in the area came Robert Kaufman of Georgetown, S. C. in a cabover model, Draggin Lady. But the rear engined boat proved no match for the conventional style hydros Empty Pockets and Miss Sapphire of Don Waldorf Jr. and Mac Jordan, both of Hayes, Va. Waldorf and Jordan easily swept to a 1 -2 victory in all heats that weekend.
Although the 266 class has suffered at times from shortage of boats it has never lacked the excitement to build up interest among drivers and spectators alike. This year Skeeter Johnson of Cambridge, Md., in the Wa Wa Too and Mike Thomas of Harvey Cedars, N. J. in the Miss Washington, D. C. are bantying first place positions back and forth between them. They're finding new competition, however, from Bob Marsh's Friskie Too of Annapolis, Md., and in the Jade Dragon, driven alternately by owner Gene Bramblett of Miami, Fla., and Charlie Dunn Jr. of Coconut Grove, Fla.
The one class flourishing in boats is the 280s. There are several vying for the best in the region. Former national champions Andy Lemeshewsky of Fairfax, Va. and Walt Struzek of Norristown, Pa., are meeting tough competition in the Rowdy of Don Waldorf, Sr. of Hayes, Va. and the Miss New Jersey of Perry Walters, Rumson, N. J. The quartet has shared the winner circle in races in Varina, Va., Washington, D. C., and St. Michaels, Md.
In the E service runabout class, which has grown to five boats this season, Ray Gerringer of Newport News, Va., is moving to the head of the pack with each appearance of his Little Lady while Bill Thomas of Hayes, Va., has been plagued with one problem after another with his High Hopes duo. The new fiberglass High Hopes, driven by Jimmy Harris of Hayes, Va., placed first in its debut at Varina but flipped during the first heat of the D. C. race, ending its cup chances for the weekend. James Leslie Owens of Hayes, Va., got his first taste of racing in his Virginian at this race and pulled in a second at the same time.
The standings among the 145s this season, remain somewhat the same with Billy Brown and his Wanton Duchess VI running a consistent first and his brother-in-law Louis Luttow and his Patchwork holding down the second-place position. The Richmonders didn't compete in D.C. so honors fell to the Blue Chips driven by Jack Sweeney of Rumson, N. J., and Cochise, driven by Joe Hart of Auduson, Pa.
Consistent title seekers among the 48s are neighbors, Dickie Loeb of Norfolk, Va. and the Betty Gal V and John Callis of Virginia Beach, Va. and driving the Stubborn Critter. Robert Letwenski, of Union Beach, N. J., owner-driver of the No Smoke VIII, is coming  from outside the region to run among the top three in the Ski racing runabout class. He has shared honors with Bright Stevenson, Jr. of Eastover, SC and Joe Maybrown of Long Beach, NY.
