Anyone have any info about what the best camshaft is for 283 2bbl,I'd like to go a little better than stock to get a touch more performance and a little pop when idling,has anyone had any success with a certain combination.I want to use the original rochester carb.Is there a way to jazz up the Rochester?I was speaking with a friend he suggested a 250h.p. cam,he thought if a guy went bigger than that the fuel shortage would become an issue.Any thoughts? Thanks
Powerglide,no I want to keep the 2bbl carb,and original intake,I want to up grade the cam,but I just wanted to know if there was anyone that had tried the same thing,and how it turned out,there must be some formula about how much fuel a 2bbl will supply over what camshaft to use.I don't know what that would be though.
You may want to dig a little deeper on the colector plate issue. When I got mine 15 or so years ago anything other than stock was a no go. I believe you can get away with era correct mod's now. chrome valve covers, vintage performance upgrades, old school mags etc.
Yes I know you can go era correct wheels,and some chrome stuff,but I couldn't answer the aluminum intake question,and I don't want one anyway,I think there are different catagories now,yes I think your correct.

The way your stock motor is set up now, any kind of hotter cam would be disasterous. You would be cursing and yelling at having to take your motor apart again to replace that hotter cam. I learned the hard way many years ago when i put a hotter cam in my 57 283 V-8. I hated the way it ran in town. On the highway it was great and ran strong but in town it sucked. If you are keeping your motor stock then keep your cam stock as well. Your motor will run far better all around. On the other hand like others have mentioned, if you go a few steps further and replace the intake, drop a 600 Holley and throw on a set of headers then putting in a hotter cam like a 350 hp cam would work well. Good luck. Cheers. George.

Believe it or not the original cam in the 1964-66, 283-195/220hp, and 327-250/275/300 were all the same profile. The difference was in the heads, carb and intake...
If you do want to upgrade, i'd look into a new technology camshaft like maybe the lunati voodoo 60100... mismatching some of the older tech cams can be problematic. There are too many things choking off your 283 right now... intake, heads, exhaust, convertor, gears etc. that will make a true performance gain hard to get... but at the same time a little lumpier cam sound is always worth it to me! btw, i've seen reworked 2bbl support over 400hp on the dyno on stock appearing sbc's for circle track cars... the magic there is head work and exhaust flow...
for fun you should call comp cams, crower, etc and see what advice they give you off of their software....if you do, please post back the recommendations...
If it won't breathe then a cam "ain't" going to a thing & may make it run worse!!! as said above "heads, intake, & exhaust will let it "flow" then go for the cam. Anything else b-4 you do that is a waste of $$$$

I was just on a web site called maximum flow carburators,I'm going to try to speek with them next week,see what they can recommend.They must know something because they specialize in it.I'll post what they have to say.

Leave it alone. The best performance a 283 2bbl can get is when its totally bone stock. Any kind of cam upgrade is going to be pointless in both lift, duration, and overlap. The GM tech guys picked the best cam and used it- why change it?

Oh my god you sound like my father,"Keep that hood closed!"I feel a little beat down,and this is input I like,I wanted some feedback and experiences so it's starting to paint a picture.Isn't a good father supposed to protect a child from making the mistakes that he made?Thanks Dad.
You could always cheat a little bit, put on a 350 intake with the bigger 2 barrel and modify the carb as someone suggested.
I ran an L79 cam in an otherwise stone stock 283 in my first 65 Canso SD when I was 16. It did have a quadrajet but no aluminum intake, no headers, all completely stock stuff. No bottom end (not that a stock 283 ever did have bottom end) but lots of RPM and very driveable on the street still. Idled around 800-900 RPM with a nice gallop to it.

you can hop up stock 283 the trick is dont go nuts, the stock cam has a low lift for a reason to wake it up run like a RV syle cam it will work with a 2bl but nothing over a 350 lift, dual pattern with more durration in the exhaust also helps.
In 66 the 195 and 220 hp 283 and 275 hp and 300 hp 327 all shared the same camshaft .399 intake lift and .399 exhaust lift with 300 intake and exhaust duration. Looks like the cam was good enough for that 300 hp 327.
isnt' that the cam you have?? the difference between those motors is the heads/intake/carbs... just my two cents, talk to a couple of cam vendors, see what they say... work out a combo on paper first before jumping into anything (and decide if spending the $ is worth what you will get out of it)... I think you'll be leaving some power/lumpy idle that you are looking for on the table by not pursuing a newer design camshaft. You will proabably also see more seat of the pants improvement in bottom end with a gear and convertor upgrade...the engine is choked off with stock accessories regardless.
I'm going to build a new motor(66 283 2bbl)for my convertible,I was just tossing around ideas,and getting thoughts from members.I was talking with a guy yesterday that put a factory 327/350 h.p. cam into a 283 with stock 2bbl carb and manifold and said it ran great,so I don't know?

that s what i am putting my 283 , but with a 600 cfm vac secondary carb
read this post from last year , there is good advice here from the boys
