Those G bodys are one of the easiest cars to work on. Literally an afternoon project to swap out that 301 turd with a 450 hp 383 in your driveway.
Their popular on the drag strip for a reason. Uncle Tony remarked he could pull a motor in like 45 min.....lol

1979 was the first year I followed Pro Stock.  

A Plymouth Arrow won the championship.  Small block (355 CI) Mopar.  The Arrow was a Japanese import (Mitsubishi), but a decent looking car in my opinion.

You are correct about what he said but 78-87 was peak GM in my opinion.  The cars were smaller than the A bodies that came before them and had large engine bays.  I would take that grand prix over any z car.

That's near the absolute bottom of the barrel in terms of domestic cars.  Only about 87 feet of vacuum lines, and a pile of emissions stuff.




You cannot buy a Kia sedan that's slower than it today.  A Kia Rio is a couple seconds faster 0-60, gets double the mileage, and isn't going to rust out/die in under 100k.

I like it. But it would likely find a 400, and some 17” American Racing wheels on it.
I’m sure finding a 400 Pontiac motor is much harder than it used to be though.

That is a pretty rare set up though.  I don’t know how many 4speed cars GM made in that body style. But I bet excluding the El Camino. They only put a few hundred in all G body’s. Monte Carlo, Malibu, Grand Prix, Regal, Cutlass. After 73, 4speeds in Mid size cars became a rare thing. And there were few already between 70-72. Usually only the top of the line mid size sports coupes got them. SS, GTO, W Buick’s and Hurst Olds.

That is not exactly fair.  Mine weighed almost what my 2015 GMC 4WD truck does.  GP's were tagged as "personal luxury" cars, not muscle cars, not sports cars.  During the GTO heydays, they were still much heavier than a GTO.

I had an SJ with the handling package and on a good 2 lane or a highway it was a good touring car for the time.  

On the highway I got good MPG, in the low to mid 20's   then when I ditched the old style cat, it ran better and got better MPG.

It always started, even in the cold.  I drove it through 4 years of college on top of a WV mountain with winter temps in the teens and 20's on a regular basis.

In those days we did not know any better.   My previous car was a 77 Bonneville with a 400.  Black with red pinstripe and red crush interior LOL  

It was a different time, people wanted different cars.  My mom drove a 4 door Bonnie.  Moms didn't drive Suburban's back then.  Guys on railway crews did.

My dad had a Pontiac, Buick, Jeep, GMC dealership, his dad started it in 1927.  For a street car I always love the Pontiac engine.  Gobs of mid range torque.  Unless worked over, most were done making power by 4500 rmp 5k max.

A lot of people were pissed at GM for killing the Indian V8.  Many felt, myself included, for a street car, it was better than the SBC.

Stuck with as in until rust do us part?  My memories of of most Japanese, Italian, British imports back then, were of listening to them rust.  Chevy Luv /  Isuzu  truck, when is the last time you saw one?  Engine was like a sewing machine though.  

Even in the early 80's Datus 210's in my OA had beer cans and scrap duct work in the floor boards.  My dad used to joke that it was because they were melting down old US tanks left over from the war.

I (briefly) had a maroon '78 GP when I turned 16.  I loved that car, but it got squashed by a drunk truck driver in a parking lot.  

I had a dark blue '81 GP briefly afterward, until some dick pulled into the road right in front of me and stopped.  It had some tiny, gutless V8 in it.  I think it was around 260cid.  

It was a nice looking car, but damn it was slow.  Even after I flipped the air cleaner cover over and put an ACCEL sticker on it.

Yep. By that time the divisions could only do design and maybe suspension changes to suit their markets. Engines by then were shared throughout GM except for Cadillac. Which was still allowed to use their own. Don't recall the Buick turbo going into any other G body cars though.

Hell no but it would cruise very nice and smooth down the highway. Only real downside it it had a horrible vapor lock issue if you shut if off hot and then tried to start it in less then 20 minutes or so. It always did start but you had to crank awhile. Never had any issues other then that with it. Got decent MPG for a big car.

Pontiac had a 265 ci (4.3L) version of the same V8 design as the 301 ci (4.9L) engine.

As you found out, it was barely able to hold together at stock HP levels which is why there were never any performance parts made for either engine.

The Olds 260 ci engine was Oldsmobile's version of the crappy 265/301 Pontiac. It never had a single performance part made for it either for the same reason.

I had an 80 Cutlass with the 260 engine. It was a gutless V8 with only a marginal gas mileage improvement over the sturdy 307 Olds V8, but I never had any issues with the 260 for the short time that I owned it.

Someone knows their stuff

The 301 was simultaneously a genius and stupid idea

It's a great candidate for an LS swap.

That would be a really cool car.

That probably went into the personal collection of the dealer.

Hell the local Buick dealer here also sold Lotus back in the day. He had 3 of these in the lower garage. Lotus only built 20 of them worldwide. Don't know if he raced them, was holding them for buyers or what. But I stumbled upon them when my car was being repaired in the body shop.

Could probably throw the obligatory LS in it and get a few more HP. Or just leave it a stock survivor for maximum MEH factor.

We had a 79 Regal.  Maroon, tan landau top, wire wheel hubcaps, tan leather interior.  I thought it was a decent car.   Of course, like all cars of the day, a weak, wheezing 3.8 v6, strangled by government regulations.

Closest pic I could find online.

We had a '78 , damn thing wouldn't get out of it's own way. It drank almost as much gas as the '70 Lesabre 350 that it replaced and was the generator of a lot of "damn I hope that car starts today conversations". The cars didn't look too bad but had dismal build quality and reliability issues. It was back to the dealer several times for them to throw parts at it under warranty until that ran out. Turns out it was less hassle and faster to just DIY it.

Still better looking than any Japanese or Korean car ever made, though.
