Thread: 283 Cam Suggestions

Tweet

I'm doing a 283 bulidup with 305 heads.. im thinking about going with a single plane intake..

im looking for a cam that will match my motor..
here are a few specs that i need somebody to help me decipher through

Intake Dur@.050 : Exaust Dur@.050 : Lift IN :Lift Ex : Lobe Cnr
1. 214 214 .443 .443 112
2. 214 224 .443 .465 112
3. 220 220 .429 .429 110
4. 216 228 .543 .480 112
5. 223 223 .447 .447 114
6. 224 234 .465 .488 112
7. 230 230 .480 .480 109
8. 232 234 .490 .490 108

Any body who knows about cams.. tell me if any of these are with in reason or any suggestions...

#1,2, number 4 is a typo. on the lift side.Number 2 is the one I would go with do to it's extra duration on the exhaust side. Both of these cams will require a stall to get the car moving.They also might need a gear change.With an engine this small you would benefit rom a dual plane manifold like a Performer,or a Performer rpm.

I believe you would be MUCH happier running a dual plane intake with those heads as single planes work best mid - upper rpm, the dual will work from idle to approx 5500 rpm which is past the stock 305's breathing range IMHO.

As for the cam choice, as for the ones you listed, I agree the #2 choice would work the best with those heads, and great behind a auto trans.

Well, I've only ever built one 283 and it was in a hyped up rage and a bet right after I blew a engine street racing. After I got my busted motor home the guy I was racing when it blew came by and started running his mouth and P.O.ed me a little more kinda like digging in a open wound and I had an old bone stock 283 in a corner that came out a '63 Impala and I told him I would build that lil baby motor and spank him right now!! He laid $250.00 on the table and told me he'd make me blow another one and take my money. So, I pulled my busted motor, went up in the loft of my shed and got down some old angle milled 461X and a matching Victor Jr. intake. I grabbed a Erson solid roller 278 and lifters out of another box. ( I think the specs were 236/246@.050 on a 108 LSA with .555 lift) I still got it somewhere. And built this motor with a used .018" copper shim head gasket and parts laying around in about an hour and a half it was running in the car. When I backed it onto the road and hit it in front my driveway, I knew what was up. This lil baby motor was pretty bad!! Ol' boy was leading the way and I was hanging back looking for my power band. When we got to the river road, we lined up, and when we took off, I thought I was in trouble. That lil motor let him jump me by a car at least but when it hit 4k RPM, the race was on. I held that lil motor to 7500 and shifted out of fear, not cause it quit pulling. I beat him by 1-1/2 cars and he came up with some lame excuse so he added another 100 bucks to his side and we ran again. I came off the line at 5k and it picked the front wheels up about 8-10 inches and was gone. I beat him by 4-cars that run and he didn't even stop and come back. I got my money from the flagger, me and my boys went back to my house to drink some beer and laugh. I kept that lil baby motor in my car while I was building another one. At the track it ran some mid to high 11s

This is by no way a recommendation for you to set your motor up like this. That was a Monza and a 4-speed with 4.30 gears and a 28" tire. Just before pulling the motor, I ran it to 8200 three passes just to see if it would do it. It acted like I babyed it. Held together with no sweat. With a career best of 11.41 and still running strong, but leaky, I pulled it and put a 383 and a automatic.

You pulled a 283 out of the corner installed an Erson soild roller cam,461x heads,.018 copper head gaskets,and you pulled the front wheels off the ground 8-10 inches in a street car?You ran it to 8,200 on three pass's.You do know there are some young kids on this forum and they might think this story is true.Some of us where born at night but not last night.Sounds to me like someone has been drinking a little to much hooch.

did he say 11.41? hmm, i mean im 21, but i have never in my life heard anything so crazy.. im just looking for the truth bout a cam..

my setup, 283 bored .040 over, 305 heads, holley street dominator intake, 65k ignition, i believe my compression is close to 10:1...

basically i just wanna put up a fight... so i guess im going with 3.73's since i heard 283's can hold rpms, and ill be driving on the highway sometimes

I would love to build a pump gas, street motor against you. I don't think you could tell the front from the back. lol
Do you realize a lot of 283s came with steel cranks instead of cast. A good setup car with a standard and a low rear gear and a motor that's not putting out enough torque to break the wheels loose will put some mometum somewhere.

Oh and btw, I didn't ask you anyway. Keep yourself out of trouble and quit quoting me. Just answer post because I'm about tired of making you look stupid. Final note is 283s don't make low torque, high horse power and you have to turn them for that. If you thinks 8200 is bad for a 283, I had a Suzuki Swift rental for a couple days that would turn 9000 easy.

I would use the Comp Extreme Energy 256 for mild everyday driver 283. The specs are: 256/268 A.D. 212/218@.050 .447/.454 on a 110 lsa.

How much hotter of a 283 could you build. Flattops and angle milled heads will equal high compression.(11.5:1+/-) That Erson in pretty big for a 283 and the 461X with 172cc intake ports is pretty big for a 283. Then a light car, pretty low gear, and a four speed. Hello, wake up, you showing everyone your smarts again.

I know there are some old school veterans on here. Tell us about the 283s and how they like RPM.

Has no one ever run a 283 screamer before?

i have a 283 bore 0.60 it screams it has no exhaust tho but it dos sceam. lol

I don't know why he would even make posts like this.If you doubted his story you have every right to.If it sounds to good to be true it probably is.I really don't think he has a handle on the fundamental's.After all why would you twist an engine way out of it's r.p.m. range ? All you do is loose power and run the car slower.Why wreck your parts?

9,000 R.P.M. Suzuki Swift?I had a Suzuki GSXR that I use to turn to 13,500 and your point is??The whole idea is to make h.p. at a low r.p.m. Hi r.p.m.s just mean more down time because you are always putting in valve springs,bearings and rings .Been there done that.I think that was about 1984.The word for you is (cycles).If you understand that then you have learned well.

Here you go showing your lack of intelligence again. He wants to build a 283. They don't make low end torque. You got to spin them to get anything out of it. If he wanted low end torque he would build a 383. Some people like to hear the whine of a engine turning 8500. It not what you want Erik, It's what whomever is building the engine wants.

An engine is not out of it's RPM range until it quit's pulling there Einstein.

Why don't you go back and read some of his posts.Now pay close attention to his possible cam choice's.Now think about the heads he has.Do you think these heads breathe well at high r.p.m.s? Fact of the matter is most 305 heads are designed for lower r.p.m. Just look at the port volume and valve size. Do you really think the any of these cams will turn a large amount of r.p.m.s? Please read all the posts before trying to respond.

Why are you telling me this?? I am not the one turning 8,200 on a cam that is done at 7,000 to 7,200.Maybe you have a custom ground cam or maybe it is more B.S..I still smell something.
