Help Picking a Cam !

Hello

I need help picking out a good cam for my 1977 Corvette.
Here's my specs:
original 350 engine (rebuilt)
Edelbrock 600cfm performer
Edelbrock Performer manifold
Lunati VooDoo 60101 (1000-5500, 213/219 @.050, .454/.468 lift)
Brodix IK180 64cc heads w/ 1.5 roller rockers
2.5" dual exhaust w/ flowmaster 40s
3.55 rear gears (auto trans)

The motor has stock crank, pistons & rods, so I can't rev higher than 5500.

I was looking at getting a 2500 stall converter and possibly this cam:
Comp Cams 282s: 2,000-6,000; 236/236 @.050;
.495/.495 lift; 110 lobe sep - Solid Lifter Cam

What do you think? Any ideas on a cam?
Thanks  

Why change what you have?

The comp Magnum cams are their older series of cams. I would guess that the difference between the Magnum 282 and the Voodoo would be 8-12 horsepower at peak, not exactly much.

Your engine has very little compression, there is no reason to go to a larger solid cam. You will just lose midrange and with your new cam choice your engine will still be all in at 5500-5800 rpm.  

My engine has approximately 9.3 compression with the 64cc AL heads. I can get more lift and duration in my rpm range and increase my hp. In fact, with my engine software, the 282s actually increased torque (20ftlb)over the rpm spectrum, as well.

You tell me if that makes sense! If you increase duration @.050 by 20° do you really think the engine will make more torque at 2500-3500 rpm? You have to consider part throttle for street cars as well...

If you think your dyno software knows more than me (which it does) then go ahead and cam to your heart's content.

I'm not saying any software is better than experience... that's why I'm here. I just thought that around 230 duration is good for the 2500 - 5500 range. Just trying to learn... Would not my engine benefit from more lift? The stall converter would get it up into that range, yes? This is not a daily driver - just a weekend car really.  

Read your post from me on CHP forum    WIEDER  

I think I am going to have to agree with GibTG. I don't think there is anything wrong with what you have now. Your combo should make a nice street car with ample low and mid range torque. You have a good set of heads for a high performance street car, but the performer intake leaves a lot to be desired. I used to have one myself and they are ok, but there are a lot of other intakes that are better for a high performance street car like yours. For example, the Performer RPM and Weigand stealth offer higher performance. I currently have a Dart Kool can intake, which is like a Performer RPM air gap and I like it a lot. To me, a performer intake is best for something like a truck that also has a small low end torque truck cam. However, you might not be able to fit a high rise dual plane intake like a performer RPM under your hood. If I were you, I would just keep what you have and get higher ratio rocker arms if anything. I hope you have headers as well.  

You neglected to tell us weight, rear gears, how many rpm's you lose each shift and tire diameter. 2500 stall means ~3000 rpm use. If you go high on the duration you will have soggy shifts. And by the time the cam comes in your engine is done. Use the torque of that thing.

The cam novice.  

personally,if i were you,i'd run comp cams extreme energy 274H.it has .490" intake and exhaust lift and 230 intake duration @.050 intake and 236 exhaust duration @.050".the convertor the cam calls for is 2200 stall,so a 2500 would suffice.this cam is more aggressive than the solid u were looking at,as you also have to factor in the lash with the solid.i'd also change the performer intake to a performer rpm,to take advantage of your heads,with a 750 cfm carb as well.hope this helps,good luck  

Thanks guys, this is all very good info. I was thinking about the Edel Perf RPM. I have a carb spacer now that fits just fine so I think I can do the RPM manifold. My rears are 3.55 right now but I don't have a prob changing them to something higher. The original curb weight of the 1977 Corvette is 3650 - but I have removed and upgraded some things. For example my aluminum heads instead of stock iron. Removed: air cond equip, smog equip, exhaust manifolds (for headers), some interior air handling junk, etc. Im not sure of rpm shift drop right now cuz im at work, but maybe i'll go home later n floor it and see - it's a nice enuf day here in MD  

Wheelsize: 8 X 15"
