I have a 1965 4 door impala with a 283 2bbl. Looking to rebuild it and want to up the performance. Wondering about heads, intake and carb. Mainly want a good motor that can pull the big car and give some good take off and passing power. Any help would be great.

Thank You,
Tim

Why not switch to a crate motor.
Even a mild 350 will be much stronger than the little 283.
Why waste money on it, put the cash to a much stronger motor.
I had a 66 with a 283 in it. It was a real dog, I think they were rated at only 170hp.
In the Summit catalog there is an all new 290hp 350 for 2600 which includes everything but the carb and dist.
You can hardly beat that by rebuilding the old little motor.

+1 Dave. I had a '67 with the 283 and Powerglide. It took off so slow that it was problematic at 4-way stop signs. I would want a 350 with a Q-Jet and Turbohydramatic, at a minimum.

+ a bunch, I been in a 68 impala with a warmed over 283 and that car was sooooo slow it would put you to sleep!  I would never waste money on a 283 unless you just had to have it for an original restoration.  

Even a stock truck 350 is waaaay better engine.

You could easily convert over to a 327 or 350 without any trouble. You'd just need to convert your throttle linkage to go to a 4bbl carb, but that's super easy and parts readily available.

The 283 may have been a hot motor back in 57 when it had a 2-4 setup with a hot factory cam and was rated at 270hp. It could run low 15s high 14s with some cheater slicks way back then and it was king of the drag strip then. That was 53 years ago, now it is not so hot any stock LT car will beat it and the LS will beat it by a bigger margin.

The motor in your Chevy is a detuned version of that and you would be lucky to get under 20 sec. in the 1/4 with your mild 283. Most of the rice rockets can beat that and that is really embarrassing.
 Time to move into the present and have a lot more fun running a much stronger engine.

+1
The 283 is a great little high reving mill if built right but still more cubic inches is better.

Hi there,
If you want to keep the 283 in and make it lift the heavy car you might use a
Close ratio 5 speed manual g/ Box which can handle about 260 hp and similar T/q.
 A 10.5" good quality clutch assembly will do fine...Skyeking

Hey everyone, don't know if you're still on here, but I am thankful your replies. Don't know what happen, I guess life got in my way. I am putting a 350 motor and trans in the Impala. I've been working on my 79 Z28 also.

Thanks again

Glad you listened to all the advice and that you returned to the site and your build.
It seems like just yesterday I was running a 283 in something but that was almost 50 years ago. I had switched to a 327 pretty soon after they came out, much quicker back then, got low 13s high 12s out of the 327 in a 55 Chevy, which was top notch in the mid 60s.
