Put a factory 305 4 bbl intake on it and run a Q-jet.
Street cam
I have a 64 impala. With a 40 over 283. I am looking for advice on a street cam. I want a highway car.
My impala has 355 gears and a 7p0r4 transmission. I am also have 305 heads. They put me at or close to 9.7:1 compression. So ya i guess i need help with a cam and intake manifold. Any help would be nice. Thanks in advance.

Thanks. I didn't think about a 305 intake.
I did think about the quadrajet. Or a 4 barrel Rochester. On the small side!

I like that cam. I was looking at another edelbrock csm with 420/442 and 204/214 on a 112lsa. And it has the same rpm range as the one you recommend.
I'm confused ny that at the moment.......
Which one do you like?
Is the 420 lift too much a cruiser?
Thanks for your help!!
I think for your small engine the 3702 would work best for going down the hi-way, get on the boat forums and see if you can find a chevy alum. dual plane intake (just a copy of the cast intake) that they used on a lot of marine engines and I would run a Q-Jet so you can be on the small barrels while cruising. Whatever cam you use be sure the springs on the heads are set up for them.
BTW, the last 283 I had was back in 76, and I have never used that cam so my advice is just WAG at best, lol, good luck.

Looks like those 2 cams look like the 2 edelbrock cams. But not as good a rpm.
This is what came on another 283 i purchased. I looked up the number and it says it's a boat intake??? Never seen a intake like this!!!I think for your small engine the 3702 would work best for going down the hi-way, get on the boat forums and see if you can find a chevy alum. dual plane intake (just a copy of the cast intake) that they used on a lot of marine engines and I would run a Q-Jet so you can be on the small barrels while cruising.

Damn! It figures! I can't seem to upload that picture. It's weird though. The primaries are one big hole and the secondaries are 2 holes like usual.This is what came on another 283 i purchased.

He's trying to guide you into something that will work good at the rpm you want to cruise in, with that little 283 the wrong cam will give a soft bottom end. The guide on that cam page is a good guide. The CCS2 cam is close to what a stock 305 4bbl might be but with better center lines and much cheaper than most other cams.Looks like those 2 cams look like the 2 edelbrock cams. But not as good a rpm.

The power range is based on Cu in, the chart is for a 350. And most likely the Edelbrock cams are Melling, reboxed.
If you are concerned only with cruise , and fuel mileage use the small one , if you want some performance at the expense of those use the larger one. Nothing is free, always a trade off.

Actually, they're both reboxed. Neither company makes their cams. They're made by Camshaft Machine Company in Michigan. If you want to buy 100 of them exactly the same, they will make them for you too, and even put them in your own custom boxes.And most likely the Edelbrock cams are Melling, reboxed.
ccs2 is not just close to a stock cam it is a stock replacement for a 67 283 to a 300 hp 350 . I haven't built a 283 since 80's but did a few of them in 70's most with stock replacement gm cam or cs274 sealed power . Some got a 350 hp 327 or something like the isky I suggested in the other thread . The small single pattern cams with the tighter lsa were the better runners . I don't think a 283 needs an extra 8-10 ex duration with a good set of duals even with stock manifolds .He's trying to guide you into something that will work good at the rpm you want to cruise in, with that little 283 the wrong cam will give a soft bottom end.

I would put a 260 comp cam with a stock qjet intake and carb on it.

I have 187 screw port heads. I want to know what everyone thinks. Should i keep them or stay with the power packs. I know I'll have to spend in some hardened seats!! Im just not sure about the low timing on these 305 screw ports. I don't even think they require a vacuum adva can. From what i read they only want 4 degrees btdc. Whats everyone think? Its either one of these. I don't have any others. Thanks for the advice!!!I've been looking at that one too
