Hemmings Motor News Blog

Hemmings Motor News has been around since 1954. We're proud of our heritage, but we're also more than the Hemmings full of classifieds that your father subscribed to. Aside from new editorial content every month in Hemmings, we have three monthly magazines: Hemmings Muscle Machines, Hemmings Classic Car and Hemmings Sports and Exotic Car.

While our editors traverse the country to find the best content for those magazines, we find other oddities related to the old-car hobby that we really had no place for - until now. With this blog, we're giving you a behind-the-scenes look at what we see and what we do during the course of putting out some of the finest automotive magazines you'll ever read.

This or That – Season 2: 1970 Chevy Monte Carlo SS454 or 1972 Pontiac GP Hurst SSJ?

Posted October 26, 2017 12:00 AM by dstrohl

Editor’s note: This or That is not a comparison report between two vehicles, but rather a feature that enables us, in an idyllic world, to add a collectible vehicle into our dream garage on a weekly basis, but with a catch: We can only pick one vehicle from this pairing, and it has to be for enjoyment purposes rather than as an investment.

We’ll launch Season 2 of This or That with a pair of high-powered personal luxury cars: a 1970 Chevrolet Monte Carlo SS 454 versus a 1972 Pontiac Grand Prix Hurst SSJ. Both of these hot performers were former features in our Hemmings Muscle Machines magazine. Unlike last season, we’ll get right to each car’s DNA after a very brief introduction.

This editions pits two early-'70s power coupes: the Monte Carlo SS454 vs. the Grand Prix SSJ.

I owned two cars which were very similar to these.

My first car was a 1975 Monte Carlo with a 454 rebuilt in my High School Auto Shop class. The car was loaded, less a sunroof, factory mags, landau roof, black cloth on swivel buckets & slap stick. With that fresh engine the car would bury the speedo past the 140mph maximum to the "k" in the word park in the gear indicator (160mph?). Beautiful car.

Later, I bought a 1970 Gran Prix specifically to sell to a friend (he ripped me off in the end). It had a Pontiac 400 that sucked a tank of fuel in 50 miles. Well, near that really. Red on black with red crushed velvet type of interior. Again, a beautiful car.

You drove a '75 Monte Carlo at 160 mph on the street??

No. Not on a "street". On the highways of central Alberta (Canada). The engine once shut itself down when the valves began to "float" and the rocker arms twisted/turned upon their perch, leaving the push rods and valves free of those levers (the rockers) on a few cylinders.

160mph is technically an approximation. As I mentioned, the 140 mark was well past way up to the "k" in the word Park on the gear indicator. No tach. A mere 3 speed. As I was 16-17 years of age, I am glad that the machine shut down via. valve float that once as I am now still alive to tell this (true) tale.

You seem to question my sincerity. ?

For what it's worth I have now grown up to drive German as the cars can sustain themselves in the fun zone.

Oh I grew up with muscle cars, I'm no stranger to speed...but I also recall that over 100mph the cars became rather difficult to control...so I'm thinking you may have swapped tire size at some point or drive train gears which would throw the speedo off....I'm afraid without a reliable collaborating source your claim is dubious to say the least....now I'm not saying it's not possible, just not probable as top speed for that car is listed at 126 possibly maybe....and I might add that I had a buddy with a 1970 chevelle SS 454 that I used to race all the time....back in the day

Needle at the "k" in Park. I have nothing to prove to you.

jus sayin , the '70 Monte carlo SS 454 came with a 2.56 rear pinion ratio...the speedo would be calibrated to the stock rearend....changing from a 2.56 to a 4.10 would read 160mph at 100mph...

I know how it works phuckhead. The needle touched the K for the third time. I was there. I assume it was stock for good reason. The dotted lines turning solid have me believe the accuracy. Who gives ashit.

I have actual friends to tend to. You're not one. Phuck off now. I have nothing to prove to you.

I told you. I grew up and now drive high quality cars. Not American crap.
