Engine Mini Series – Chevy’s 283 Prt 2
January 9, 2011




Oh yes, believe it or not, the 283 put the Corvette at the cutting edge of performance in 1957, fitted with the RamJet FI (fuel injection) system (“fuelie” was the gearhead term for that). In 1958 the 283 was the base engine for the Corvette, but the 283 that use to put on 283 hp was tuned to create an even 290 hp. If that wasn’t enough for you (of course it wasn’t enough, two words that should never be heard together ‘enough’ and ‘horsepower’…unless…the word ‘not’ precedes them). The RamJet FI was an available option RPO 579D.

Additional configurations were dual four barrel carbs that produced 270 hp, they were either Rochester or Carter AFB. The cam was changed in 1958 to give 0.398 inches of lift, improvements made to get more oil to the lifters and the exhaust manifold was reworked, called the Ram Horn’s manifold. There was a change in how the 283 was mounted. Chevy used the 3 point system with a mount on each side and one at the rear of the engine at the transmission.

In 1961 the FI jumped the engines’ horsepower to 315. (Hey, the base corvette in 2007 was 400 hp.) The FI wasn’t the only improvement for the 283 in 1961. It was treated with a set of solid lifter, improved heads and hydraulic cam which helped the block rich 315 hp, easily. This would be as far as the 283 would go in horsepower – in production. 1961 was also the last time the dual four barrel carbs were available as an optional configuration.

By 1962 the 283 was replaces by an entirely new engine the 327 (that’s another mini series) as the premier Chevy small block. The 283 was dropped from the a power plant for the Corvette to a base engine for Chevy’s passenger and used from 1963 to 1964. Its horsepower dropped to 170 and 195 for two configurations. A small bright was a four barrel configuration for 1965-67 that produced 220 hp. (That was the configuration of my 1966 Impala convertible.)

Of note is the use of the 283 in Chevy’s light trucks with a two barrel configuration for most of the models in 1958 to 1962. It produced only 160 horsepower. For the 1963 to 1967 light truck models the hp was increased to 175.

1967 was the last year for the historic 283.

Part 3 is not related to Corvettes so I'll not post it here.

Coming up next a recap of the uses of the 283.

Thanks for reading.

Engine Mini Series - Chevy's 283 Part 3

OK..OK...out fear from the previous Thread Threats..here is Part Three. Sorry the pics aren't showing - can view on my site http://wp.me/pKHNM-nT

This is the part of the engine series where I list the uses for the power plant. The 283, as I mentioned, carried Chevy engines to the next level, by being the first engine that car manufacturers were able to coax out the same horsepower as the displacement.

From 1957 (its inception) to 1959 the 283 was the base model V8 for nearly all Chevys, coming in a 2 and 4 barrel versions with the 4 barrel being the main power plant for the Corvette. In 1958 the 4 barrel version was dubbed the Super Turbo Fire with 220-230 hp with 9.5:1 heads. (Toss that name in with other versions like the 348 Turbo Thrust and the Super Turbo Thrust which sported 3 two barrel carbs.) The other premier engine during that period was of course the FI used in the Corvette with 9.5:1 and 10.0:1 compression.

The 283 Super Turbo Fire

1960-1961 saw the base 283 drop to a 2 barrel and muster just 185 hp. The bright spots were engines used only in the Corvette, the dual quad and the FI engines. 1961 also saw the 283 go MARINE – nope not joining that elite military branch but rather Chris-Craft the boat builder, sealed it tight and give a duty on their Cavalier Cruiser vessel.

Not much changed in 1962-1963, at least nothing very exciting. Chevy dropped the dual quad as an option (although I bet you could still get it done) and the 283 dropped in hp to 170 and as was no longer an option for the Corvette, but was added to the Impala.

As perhaps a last chance to breathe some life into 283 Chevy gave it a bump in hp to 195 and it found a new home in the new Chevy II in 1964 and 1965 a 4V was added give the iron 220 hp and another new home the ’65 Chevelle.

But that couldn’t save the 283, it was time for Chevy to move on and 1966 was its final year. It served as the base V8 that year as an option for the Chevy II and Chevelle and the other Chevy sedan’s, like my 1966 Impala.

Although it seems like I give this a quick pass (not a long list of models) the 283 served nearly all models of Chevy from 1957 to 1966, listing them all would be, well ..repetitive . Interesting enough it never crossed over to the other GM brands. But it did make it into the Canada made Studebaker cars in 1965 and 1966.

During the it’s life span the 283 was offered with every transmission available for that year. From the torque glide to the power glide automatic transmissions and even a few 3 and 4 speed manuals. Additionally, I was surprised to find that it was offered with air suspension with some automatic.

Did the 283 really die? Nope it received the cam from the 327 and became Chevy’s 307!!

Notable:

- The 327 followed the 283 and although it was an entirely hunk of iron, to keep cost down Chevy used some 283 components initially.

- GM’s RPO 579E option on the 283. 579E was called the Air Box. It was perhaps the first production cold air induction system(at least for Chevy). It consisted of a plenum box mounted on the fender well of the driver’s side. The box was fitted to an opening in the bulkhead next to the radiator with an air filter inside. The duck work ran to the fuelies injection unit. Records indicate that there were only 43 produced in 1957.

1957 Corvette AirBox

- Corvette Fuelies had a reputation for hard starts and finicky operation and many were replaced with the standard carburetor (1957)…Flash Forward the 1984 Corvette Crossfire (fuel injected) (Of which I was a previous owner) suffered from finicky operating and some were replaced with carburetor set ups.

I hope you enjoyed this little bit of engine history and as always, thanks for reading.

:partyon: Thanks Tim

Als I believe you mistyped about the 307, it used the 283 bore witha 327 crank:thumbsup: And the DZ302 of Z/28 fame was a 327 block witha 283 crank
