The first ‘Indy’ US nationals – Names like ‘Dyno’ Don Nicholson, Arnie ‘ The Farmer” Beswick, The Ramchargers, Bob Ford and Jim Wanger Pontiacs start to become household names. Stock classes were divided up – S/S was <10.59 lbs per 1 HP. Open exhausts permitted. Traction bars and any gear ratio. | |||||

CARS & DRIVERS NOTES
FACTORING
Cars were classed in Stock Division by weight divided by horsepower. It provides a very good indication of how competitive a car might be in class.

DRIVERS
Regardless of disqualification, the ‘top dog’ drivers of both National meets were ‘Dyno’ Don Nicholson and Hayden Proffitt. This led to a fierce rivalry betwen the 409cui Chevies and the 421cui Pontiacs.
Don Nicholson – Nicholson earned his nickname by exploiting the new chassis dynamometer to set up his cars before racing at the track- this circumvented wasted tuning time on race day and allowed for continuous development.
Hayden Proffitt – Proffitt drove for one of the biggest names in racing, Mickey Thompson. The pair put countless hours into vehicle preparation.
Other notable ‘hot shoes’ were Arnie ‘The Farmer’ Beswick (Pontiac), Lloyd Cox (Pontiac) and Frank Sanders (Chevrolet).
DISQUALIFICATIONS
There were no notable DQ’s in the top classes at the WinterNationals except for the A/SA class.
Indy provided a different scenario however –
Richard Hilt – Was DQ’d from B/Stock – illegal valves – taking with him r/up Bruce Morgan.
Dyno Don Nicholson – Was DQ’d for illegal valve springs and as such lost the Top Stock trophy. The r/up was not awarded the win and the whole eliminator voided.
Controversially, he was allowed to retain his OS/S class trophy he won earlier, even though he ran the same illegal combination.
Arnie Beswick – Was protetested and controversially lost the S/S trophy. Again no trophy was awarded to the r/up, Mickey Thompson.
Arnie Beswick speaks :
– “Here’s the same 1961 Ventura facing Dyno Don’s 409 with updated sponsor art at the 1961 U.S. Indy Nationals. I’d already won S/S, and Dyno Don had taken the Optional Super/Stock title—or so we thought. But this run was for the overall Mr. Stock Eliminator title. Don’s 409 had new heads and carburettors since its Winternationals victory and beat me in this race, then the Ramcharger’s Dodge for the win.
But after it all, he was declared illegal due to questionable valve springs and the bigger AFB carbs. As for me, my 389 was declared 1.5 thousandths oversize on one cylinder and booted out.
I raised Cain and hired one of Roger Ward’s Indy-car mechanics to measure the bore again. It came up one-thousandth less than the allowed 0.060 overcut. Mickey Thompson’s seven-car fleet of Pontiacs had the same machine work—but nobody protested them.
The tech people were in bed with Mickey’s team, for sure.
For having the nerve to dispute the NHRA’s ruling, I was banned from competing in any NHRA national competition for the 1962 race season, but it
was no big deal to me. I had plenty of lucrative match races to fill in the void.”
CARS
PONTIAC – Its safe to assume most Pontiacs running in S/S in 61 were the 389s with 6V tri carbs.
Towards the end of the year the really serious teams pulled the old 389 cui 425-A engine out as it ran factory cast crank and pistons. Instead they installed one of the “available over-the-counter only” super- duty 389 engine blocks. It had four-bolt main bearing caps a forged-steel crank and a heavy-duty oil pump and an 8-quart oil pan.
The pistons were forged with 11.2:1 compression ratio. The cylinder heads had larger valves, hardened high-ratio rocker arms and heavier valve train.
However prior to the September 1961 NHRA Nationals at Indianapolis, Pontiac introduced a new 421 cubic inch engine rated at a ridiculously low 373 horsepower. Reality is they made closer to 460 HP. The engine featured dual four-barrel carburetors, a solid lifter cam and available only with related heavy-duty driveline components.
These few SD 421’s were issued as crate 421’s to specialized teams such as Mickey Thompson (Proffit was running one), Royal, Ramsey etc to drop in their existing ‘61’s where they ran OS/S at Indy ‘61 (pre cursor to FX)
Most S/S 61s ran the 389 with Tri Power for 363hp which was probably under-rated.
CHEVROLET – By 1961, in the Impala SS only, the high-performance 348 cui engines or the new 409 4V could be ordered.
The 348 could be ordered with up to 350hp and the 409 V8 made 360HP and later 380HP….terminating at 409HP with dual carbs and solid lifters.
Responding to Ford’s 390cid V8, the 409 was a bored and stroked version of the 348, equipped with an aluminum intake manifold, a Carter four-barrel carburetor, a solid lifter camshaft and an 11.25:1 compression ratio. Impalas ordered with this engine would only be built with a four-speed manual transmission. No choice of axle ratios was given.
In August the dual quad and cam service package became available making 409HP. Cars running this set up were put in OS/S at the Indy Nats. Notable drivers were Nicholson, Strickler and Sturm.
FORD and CHRYSLER – Were relatively noncompetitive at both meets, although the Optional Super Stock class at the Indy Nats gave the Ford teams the chance to shed some weight – which they put to great use with the 401HP 390 tri carb motors.
FORD – Ford started the season with a 375 HP 4V motor, later increased to 401 HP 6V (3 twin throat carburettors)
The 390ci block used in the super stock car was totally different from the standard production 390. The block casting was internally heavier and had a special oiling system cast into it. The crank was still only cast but very durable.
The camshaft used mechanical lifters that would easily rev over 6500 rpm. Using the same aluminum intake manifold and Holley four-barrel carburetor as on the ‘60 engine, the ‘61 Ford entry into Super Stock was rated at 375 horsepower.
There was also a cast-aluminum intake manifold that mounted three Holley two-barrel carburetors. The 6V Package brought the horsepower rating up to 401 and was released just prior to the ‘61 Pomona Winternationals.
A heavy chassis hurt the brands chances.
CHRYSLER – Mopar (Chrysler, Dodge, Plymouth, DeSoto) had no production car at the start of 61 that met S/S class ratings.
The Ramchargers 62 Dodge coupe – The engine was 0.060″ over 413 for 426 ci. It had flat top pistons and the heads and block were severely cut to get more than 13:1 compression ratio. Blown head gaskets were a frequent problem. Hoover left off the expanders behind the oil rings to reduce friction. The car burned so much oil that at the finish line it was not visible from the starting line.
Jim Thornton designed the cam, which at 292 degrees duration was more cam then had ever been run in a B-engine. Valve gear was C-300 hardware. Intake manifold was the “over the valve covers” long ram – modified to be a short ram.
The 413 cui and 383 cui Long Ram ‘Sonoramic’ manifolds made good torque…to shift the heavy 300 series cars….but only over a narrow power band. They also powered the 60 & 61 Dodges & Plymouths.
MEETS
Winternationals – Pomona, CA – February 19 – NHRA started its expansion to the west coast with the establishment of the Winter Nationals, run at the Auto Club Raceway in Pomona, California. It would soon be known as the ‘Big Go West’. An estimated 40,000 fans attended.
Nationals – Indianapolis, IN – September 5 – Equally important news was the move of the US Nationals to Indy race way – It became known as ‘The Big Go’. This gave competitors two National events to strive to compete in, one on the East Coast and one on the West…..and both events were greeted with great enthusiasm by the rapidly growing fan base of drag racing,
Regrettably a technical disqualification to both drivers spoiled the Top Stock run off at the US Nationals, the most prestigious stock class final of the year.
CLASSES
In 1961, cars ran off for Class trophies.Time trials were run to qualify for Class.
There was also a final ‘Elimination’ contest where qualifiers competed for the ‘Mr Stock’ or ‘Top Stock’ prize.
SUPER/STOCK – In 1961, the top class was intended to be S/S at 0 – 10.59 lbs./hp. power to weight ratio. The class was part of the Stock factory car race division….S/S ran off in the eliminations with OS/S, S/S,S/SA, A/S, A/SA,B/S and B/SA.
OPTIONAL SUPER/STOCK – OS/S ran the same weight break as S/S, but were allowed extra modifications. It was was hastily factored in to the Stock classes when GM sent both Don Nicholson and Frank Sanders a new dual quad hi-rise intake between the Winters and the Nats – this brought about the inception of Optional Super Stock- as did the limited release of the Pontiac 421 Super Duty dual quad carburettor engine.
NHRA could see a need to provide a class for the latest ‘modified’ factory stockers. Take a 61 S/S 409 cui Chev Biscayne, add wider tires, aftermarket exhaust headers, traction bars and a cold air scoop and you have an OS/S car. The Genie was out of the bottle…and Factory Experimental class was just a season away.
