Hi guys, I'm a rookie on the subject, my chevelle 65 currently has a 250 engine, however a friend has a 283 engine from a 64 chevell, he also offered me a 350 engine but more current . I liked the idea of mounting a 283 engine to my car to be according to the year of my car, but I would like to ask what they think of the 283 engine and if you have to choose between a 283 of the 60s and a 350 of the late 70s what would you choose?
Sorry for my english haha.

Nothing wrong with a good 283 that has some power pac heads on it. Add a Performer, a 500 Eddy or 585 Avenger carb and a small set of headers and you should have a snappy little street combo.

If you are going for an original look, then use the 283. If you are going to hop it up, then bigger is always better.

From a looks standpoint, what difference would there be if it was a 283 or a 350? Install an intake with the oil filler tube and I can't imagine anyone knowing the difference.
From an originality standpoint, since it had a six, going to a V-8 already makes it non original, why not enjoy the extra cubes?
Just my .02,

350 five days a week, and twice on weekends.

A 283 is not a "horrible" engine, but it's a turd when mated with a Powerglide. 283/TH 700 could be an adequate combination.

Everything a 283 does, the 350 does better.

Yep, I agree w/everything.

I have 283 w/Powerglide on my ‘66 and even though I converted it to 4 barrel, dual exhaust, that Powerglide is making the car a slug. Car is a cruiser though, I put about 6K miles on it per year so it’s ok, but Powerglide is coming out over the winter.

I had a 283 with a powerglide 2 speed trans in a 66 Impala coupe.Man did that engine and trans combination leave you wanting for more cubes. :boring: Don't get me wrong even with the factory A/C it moved along just fine everyday but from a performance standpoint :boring: it was way underpowered.
Here is some advice from someone who had owned a 283 as a daily driver for about 3 years, get the 350 and don't look back.:cool:

Where's your location ? are there any hop up parts readily available for that 283 where you live ?

Take his advice. What was fast in 1965 is a real dog by today's standards. I kept my original 327 with a 2004r and it's adequate but I wouldn't call it a fast car, just a cruiser. You get spoiled by driving modern cars and then comparing it to old iron.

Torque, torque, torque. A 327 came with the car so you could go with that if you are trying to stay period correct. Cubic inches are key on the street car like this. Even with a small block the Chevelle can be heavy. The extra 50 cubic inches from a 327 bored 30 over to a 332 will really help. A 350 would also be good (with period correct look) but if you were trying to be period correct the 327 is the answer. I agree with the above, a 200/700 r would be another nice add on. I think a 350 has like 80-100 more foot pounds of torque than the 283 which is huge in this type of situation (like 30% more tq).

Except for gas mileage.

You can pull down some really excellent MPG numbers with a stock-ish 283 and 3.08 gears. If power is not a primary concern, and road trips to car shows, etc are in the plan, I think the 283 makes a fine choice. 22-25 mpg on a highway cruise should be easy if the 283 is left in a close-to-stock configuration and well tuned.

Years ago we were getting 23-24 mpg highway from a stock 307 with the small 2gc carb, stock "ThermAC" air cleaner heat, etc. Of course that's back when the speed limit was 55 and everyone drove 65 mph or under.

Of course, you can get 20 mpg with a 350 if you build it right, and it will be a lot more fun to drive. Maybe the 3-4 mpg trade-off is worth it.

Anyone that tells you a 283 or a 307 is remotely acceptable from a performance perspective is giving you bad advice.

If a Power Glide is involved, it's extremely bad advice.

Neither a 283 or a 307 mated to a PG can get out of its own way. The motors are a better alternative to pushing your car manually or driving like Fred Flinstone.....but that's about it.

Even a modest 350 will make gobs more power than a comparable 283 or 307. Cosmetically, there is no real, visual difference.....save for the possibility of an oil tube.

Even if you went with a post 1986 350, you'd have a hard time distinguishing it from a 283....unless you went Vortec. (Frankly, I wouldn't be remotely afraid of going Vortec.)

Ya 283's and a P/G make for a snoozy ride for sure. One thing I learned when I was young was how to make a small cube engine run as that's all we could get for cheap. We used Vega 4 speeds with a 3.11 1st gear, mild 350hp 350 cams, 461 heads with 1.94 valves (2.02 won't clear the cyls) and put a little gear in the car. Sure was fun spinning those 283's to 7500rpm. Bad thing was once in a while they would blow up, LOL. My favorite small engine was a 307 which was just a stroked 283 and with the parts mentioned above but I used Powerpac heads and that little Nova I had was a fun combo to drive. Car ran high 13's with a 3.08 and you could drive it to the track. Today with a 283 and some Vortec heads milled down to raise the compression a bit I am willing to bet a 283 would scream with those heads.

I have had a 307 and a 350 in my 68 chevelle. The 307 was the original engine that I installed a 4 bbl manifold, qjet and headers. It was tolerable with the power glide but nothing to write home about. I put a 700r4 in and it was a different car. Even with the 3.08 gears. I put a 350 in with a mild cam and same transmission and gears and it was a lot more fun to drive. As far as mileage the hit was only 1 mpg. Point is the 350 is not going to be that big of a hit on mileage compared to the 283 if you are conservative with the cam spec but you will have a lot more fun. I doubt this car is your daily driver so what difference does a couple mpg make if you want to have fun.

Can't argue with this for performance, but having had experience with both 283s and 307s w/ Powerglides, I think a lot of you guys are REALLY exaggerating. ;)

When I first got my Chevy II on the road in 1988, I had a very tired, oil burning 283 with a PG and 3.08 gears. Stock 220 hp engine. It went 16.3 consistently. Yes, that *IS* very slow, and any modern 4-cyl sedan will run a faster ET. However, it kept up with traffic and had no trouble merging on the highways. Remember a "HOT" brand new 305 TPI IROC was running mid-15s back in those days, and that was fast compared to most new cars of the time.

It's all about perspective. If performance is the goal, go 350 and don't look back. However, don't let these guys make you believe you'll get run over by a prius if you go 283. LOL :D

Now if you are talking about a 230 ci engine and a PG... well... yeah, you may want to rethink that decision. I had one of those too... I think mister Flintstone COULD have outrun that one.

Wow, you guys are harsh on anything not a 350 or bigger!

Not everyone is drag racing, there ARE other forms of automotive play-time.

And yah, I'm building a killer 327 for my '68, partly to NOT be just another 350 or bigger.
