bolt on upgrades to a stock 283 with 2 barrel carb?


Hi guys I thought I might throw this out there considering the overwhelming support and help I received on my first welcome aboard post.  Here is what I am wondering.  I have a unmolested stock 64 283 that runs well except for some smoke when she warms up.  Everyone I have spoken with attributed this to valve seals so I'm going to do them asap.  Other than that the only improvement so far was a Pertronix upgrade to electric points (thanks rabbit64cs) which has been done.  Here is what I am thinking and looking for opinions/advice on.  There is a guy near me who has a ton of sbc parts  He has offered me a clean edelbrock performer intake and my choice between a carter/holley/edelbrock carb.  I was thinking I could swap the intake manifold and carb out and keep originals (for nostalgia) to give it a bit more pep.  Has anyone done this or know of it being done and what type of results were achieved?  Would you recommend an exhaust manifold swap to headers and dual exhaust as well?  I think the intake and carb swap should be a simple as a couple of gaskets but any input would be appreciated.  Kevin had told me a 4 barrel would add considerable hp to an older 283 and everyone says they are almost bullet proof so i don't think these conversions could hurt an older engine and tranny could they?

Thanks

RE: bolt on upgrades to a stock283 with 1 barrel carb?


Your engine would have come factory with a 2 bbl. carb. Horsepower jumped from 195 to 220 with a 4 bbl and dual exhaust.

headers on a 283 might give you another 20 hp.  These changes would wake up your 283 without harming drivability.

Just a comment on the smoke.....try SeaFoam in the oil.....got rid of the smoke in a few cars that I know about.

Follow the instructions on how to use the stuff.

A replaced carburetor, intake, headers, & dual exhaust won't harm the transmission or rear end because the horsepower gains won't be too much.

to complete the factory upgrade of 25 hp.a clutch fan was included with the 4 bl & dual exhaust........don't ' cam' it if you change to an overdrive trans (200r4 bolt in)

Just don't make the two most common mistakes people make doing upgrades on a 283-

1) Too much cam if you change the cam

2) Too much carburetor if you change the carb.

Been there, done that when I was a kid. The too-much-cam is the worst one. It sure sounds tough, but when you stand on it from a dead stop it has much less pull than when it was stock!

X2 on the cam.. don't even bother with upgrading the cam.. been there .. done that.. 

here's what I did years ago and chased my tail  after ..

fresh 283,  added a 300 hp 327 cam, edelbrock dual plane, quadrate 4 bbl,  HEI and headers..

running it in a 50 chevy ˝ ton, sub framed, lowered , with an T350 auto and 2.73 gears..

 

IT was a dog until 2800 o 3000 ish RPM.but then it went !!

so.. I added a street stall 2800 ish to the drivetrain,, that helped get it up out of the hole.. but it still did not pull until it was on top of the RPM.

 

the mild upgrade with intake and 4 bbl,  even going to 2 ˝ ram horns will give you some more hp but it's going to 'sound' like your making 100 hp more !!

         (Keep it simple and in-expensive)   A "small" 4bbl and dual exhaust will make it "peppy"     Its a 4 door 4000 lb hardtop  not a race car

I would not bother doing anything to it, if it runs good, leave it alone,  those 2bbl carbs are the best damn carbs in the world, you will never have a problem with it,  good choke, great driveability,  ungrading to a 4bbl will make no difference,  its a 283.  especially stick with the stock cam,  has the best low end torque curve.  if you plan to drive the shit out of it at every stoplight then upgrade it by all means,  and if you plan to rev it to 4000 rpm 95% of the time,  then upgrade the cam.

I all depends of what you are going to do with it,   if you want more power,  replace the motor with a larger displacement, or replace the car with a different car

Its a 64 pontiac 4dr 283, enjoy it for what it is!

Can't argue with that logic. In the small block world, for a daily driver car, there's only one thing better than a stock 283 and that's a stock 327!

As everybody else says......just tune it and drive it.

I put over 3000 miles on MY "tired" 64 283 2bbl. with 'glide last summer..... and enjoyed EVERY minute...

AND there is nothing like that kickdown into low @ 45 or 50 mph.....if that's working right,you don't need a 4bbl.....

I had a 65 Custom Sport a few years back with a 327 4bbl. and I think the 283 2bbl. would have kicked it's butt in a drag race....

 I agree, if you want a bit more pep but still want a daily driver go for the intake and carb ( just don't over carb as stated). These 283's came factory with dual 4's ( Corvette) and fuel Inj,diff cam&heads. Do what you want your the one driving the car, your not going to harm a 283 by putting on an intake and carb. But it will be a lot more fun to drive if that's what your looking for. 

283[edit]

The 265 ci V-8 was bored out to 3.875 in (98.4 mm) in 1957, giving it a 283 cu in (4,638 cc) displacement. The first 283 motors used the stock 265 blocks. However, the overbore to these blocks resulted in thin cylinder walls. Future 283 blocks were recast to accept the 3.875 bore. Five different versions between 185 hp (138 kW) and 283 hp (211 kW) were available, depending on whether a single carb, twin carbs, or fuel injection was used. Fuel injection yielded the most power topping out at 315 HP in 1961. Horse power was up a bit each year for 1958, 1959, and 1960. The 1957 Ramjet mechanical fuel injection version produced an even 1 hp per cubic inch (61 hp/L), an impressive feat at the time. This was third U.S.-built production V8 to produce one horsepower per cubic inch.

Not all 283s came with 2 barrels, in '64 283s came with 2 or 4 barrels, check head numbers some are 1.94 @9.5 to 1 and 2.02 @13 to 1. Most reliable motor of all time. 283s can produce up to 400hp. I've had a 283-2bbl cruising out at 123mph, motor had more but car couldn't handle it.

That's what I was hinting at when I said this: "A replaced carburetor, intake, headers, & dual exhaust won't harm the transmission or rear end because the horsepower gains won't be too much."

It also would not be cost effective in my mind.

I'm just going to upgrade from a single to a dual 2" exhaust when the time comes. I've already refurbished the stock 2 barrel carb & intake, plus the exhaust manifolds. Mostly time and some money, well spent.

I agree with everything that is said about the 283. My 62 has the original 170 hp engine in it. It, however, has an edelbrock 600cfm carb. and manifold, headers, dual exhaust, and a HEI distributor added. Even though the compression is at 120psi on 6 of the cylinders and 80 psi on the other 2 cylinders ( should be 140) and it has some blowby it still is amazing how it runs and pulls. I just picked up a really good 350 and a 700r4 xmission for a price that is not even close to what it would cost to overhaul the 283 so for the time being it will receive the swap. This will give me a chance to have a look at the 283 as it is number matching.

Thanks for all the input guys, you have given me lots to consider. I think I will hold off on intake and carb until we go on our first road trip and I get acquainted with her and see how she performs. I'm going to drain the 5 year old gas today and fill with some fresh stuff and let her run for 30 minutes and see if she stops smoking. If not I found two completely rebuilt heads for 500 that I will invest in instead. I also changed out oil and filter and used valvoline high mileage with zinc and a litre of Lucas oil so hoping that may help too.

Ditto on the SeaFoam additive. Works wonders. A 4bbl swap with an aluminum intake(used ones are plentiful around $50) and Edelbrock carb is a decent improvement as long as you add dual exhaust. But as long as the 283 is running well just leave it alone until you have to tear it apart due to smoking. The best way to improve drivability in these cars is switch the slip'n slide PowerGlide to a 200 R overdrive unit.

         IF it needs valve seals  you are going to buy other heads?    interesting

 I'll have to try the Seafoam on mine....what exactly is that stuff?

 

 Also please explain how you figure a 200r4 is better than a Powerglide....?no

  1. Sea foam. Sea foam, ocean foam, beach foam, or spume is a type of foam created by the agitation of seawater, particularly when it contains higher concentrations of dissolvedorganic matter (including proteins, lignins, and lipids) derived from sources such as the offshore breakdown of algal blooms.

Better all around performance, extra gear and lockup. Improves mileage, saves wear, quieter, better top end speed to name a few.

 First things first......the transmission conversion cost is likely going to be what....?    ballpark $2000.00...probably $2500.00?
