383 stroker witch Cam??

I have 383 stroker engine and I am looking for a new cam.

The question is, what would be the best cam for this engine?? And what springs would work with this cam and these heads??

It's chevy 383 stroker engine with Dart iron eagle SS heads. 72CC chambers. 165CC runners, 2.02 intake and 1,96 exhaust. Edelbrock RPM manifiold. Long tube headers.

Compression end pressure is 184 PSI. I think compression ratio would be arround 1:9,5

The heads may be a little on the small side for a 383. However, if you are using them a comp cams XE274 would work well with those heads. Use the springs comp recommends or buy the kit cam and springs etc.

a cam like this would be great

111213-10 NA 261 269 229 237 .555 .555 110 106 .022 .022 1,2,5
2000-6000 Noticeable idle, good for Weekend Street Cruiser. Should have 9.0:1 CR, 2000+ stall.

those small heads would make for very fast throttle response.

a 750 holley would work well

I am planning to use a flat tapped hydraulic cam..

What cam would you recommend?

I was thinking about a comp cam; XE274H

XE274H: 274/286 duration, .490/.490" lift, 110 degree centerline

Would this suit my heads?

That cam would be ideal for those heads. You could also tighten up the lobe separation angle which is 110 to 106, which may give you a little more torque down low and give a little mor elope at idle. However, it will still be totally streetable. It would make for a nice street driven motor.

Ok thanks.

What timing chain would you advise or do you prefer yourself? Mine has a bit of slack and I'd like to replace it. It is a double row chain..

I usually use a Cloyes as well. Get a basic double roller and it should be fine. Comp timing chains are also good.

Vinnie, That cam you suggested looks good, but seems to have a lot of lift at .550 for those cylinder heads which have peaked by .500. Any advantage to going beyond the .500 for lift. I though it may be more streetable with the .500 lift cam, a better match for what the cylinder head is, which I beleive only flows to about .500.

The cam does lift to 550,true.Remember thats the peak lift.The cam spends most of its time opening to 500 or closing from 500.so it looks good to me from that perspective. Also,that cam should make power to 54-5600 in a 383,and the heads though a little small will be close to max flow with that cam.

I did say a cam like this,doesnt have to be exactly this cam. I think a fair amount of people leave a lot on the table,especially the users that use flat tappet hydraulic cams. This little roller would really be quick throttle response and make good mid range power.

Of course the heads could be ported and a bigger cam used.If a hydraulic flat tappet is used,then the 274 is as ok as anything in its class

The heads are lame. You need heads before you need a cam.

I am looking for some streetable horsepower. I know the runners are a little small, but I don't want to go to far this time.. I also got a 327 that deserves some attention..
Can you give an estimate of the power it will give?

Would you advice a stall converter with this set up? I am using a TH700 with lockup, got a 3.73 ratio and 275-60-15 tires. I will be doing 2200 RPM at 70 mph.

See there, some plain old common sense.
