1964 Rambler 770 Typhoon – America’s Newest And Hottest Six Cylinder Engine Gets A Stylish Wrapper

In fact there were several excellent new pushrod sixes that all performed better than lots of folks assume. Perhaps somewhat surprisingly, it was Rambler’s new Torque Command 232 six that was arguably the best of all of them, especially in terms of performance.

Fitting for a company that was so heavily dependent on sixes, AMC decided to create a special version of the Rambler Classic 770 coupe just for the introduction of the new six in April of 1964, dubbed the Typhoon. Given that 1964 was the year Pontiac introduced the GTO package on its mid-sized coupe, the Typhoon was clearly making a statement of its own, and one used right on Rambler ads: “The only race Rambler cares about is the human race!” But don’t try racing against the new Rambler six with your six or even a mild V8; you were almost certain to lose.

As to the question at the top of this ad, the answer is simple: Rambler didn’t actually have a genuine “high performance V-8”. Yes, back in 1957, the 270 hp 327 V8 in the quite light Rebel of the times was genuinely hot, one of the fastest stock sedan that year, although AMC didn’t take it to any stock car races either. It was quickly dropped after 1500 were built. By 1964, it was still a decent performer but not even remotely in the same league as the hot V8s from the Big Three. Now if NASCAR still had a compact car series as they did back in 1960, it might have been a different game.

What makes me so hot on the new AMC six? I always knew it was an excellent engine and a good performer, but when I wrote up this vintage review of a rather similar 1965 Rambler American 440-H coupe, I was rather shocked. Despite it being saddled with the generally less-than-stellar Borg Warner 35 automatic, it zipped from zero to sixty in a very brisk 10.9 seconds. That’s the best 0-60 time I’ve ever encountered for a six except for the high-performance four-barrel OHC Pontiac Sprint six, and which only managed to improve on that slightly with a 10.0 second time in the recent vintage review of a 1967 Firebird Sprint, and that was with a 4-speed manual. This was the whole reason I went off the deep end with my analysis and projections, dubbing the Rambler American as the fastest pushrod six in the land, with a projected 0-60 time of 9.3 seconds in the lightest body style and with the 3-speed manual transmission.

So how quick was the Typhoon? There’s no ready vintage reviews, but since it weighed some 180 lbs more than the 440-H and had 10 fewer horsepower (one barrel carb vs. two-barrel), one must assume it was a wee bit slower, maybe 11.5 seconds to 60? But that’s with the automatic; with the stick, it would almost certainly be closer to 10 seconds. Just to reiterate: that was quick back in 1964, likely even a tick quicker than the ’63 Chevy Biscayne 283 V8 with 3-speed manual in this vintage review that clicked off a nippy 0-60 time of 10.7 seconds. Hot Rambler! Who needs a V8, especially since the old AMC V8 was excessively heavy and really impacted handling negatively.

Print materials, naturally, embellish AMC’s efforts to some degree; still, cooler heads did approve the new powerplant. A period CL review went into detail: “The new engine follows the pattern of its forebears in being a straightforward, simple design. Although 3 in. longer than the 196 block, it is 2 in. shorter in block and height, and all-up weight remains the same…

The crankshaft is the main departure from the norm –it runs in seven main bearings where heretofore Rambler’s sixes ran in only four mains… The result is obvious: A stiffer crankshaft, more able to withstand higher piston pressures and bearing loads… Durability and longevity are greatly increased.”

Overall, the new powerplant achieved the company’s expectations, and it would prove long-lived; versions of the engine were still powering Jeep products in the early 2000s.

To introduce the Torque Command 232 in the spring of 1964, the Typhoon limited edition was created using the Classic’s 770 hardtop line, at the time, the company’s top-of-the-line mid-size model. It carried a unique 2-tone color combination in Solar Yellow and black, with a neat side spear and other minor trim accents. The sharpest of the 1964 Classics? Undoubtedly.

Of course, 1964 would be the last year that AMC’s lineup would be so “sensible” and straightforward. Starting in 1965, AMC’s star-crossed quest for sixties coolness and relevance would start in earnest, with the arrival of the fastback Marlin. A Quixotic quest for sure, but that’s part of what makes AMC’s tale so fascinating.
