Hey guys got a 74 L-82 350 4speed corvette recently do not know much about it though. I assume it has a crane cam 10072 in it because I found the cam info sheet in the car about all I know. http://crane.carshopinc.com/product_...d/15842/100072

Does anyone know if thats a mild like stock cam? or is it high performance. Im looking to make this car a driver and be pretty much stock.

I also need a carb and am considering a Edelbrock Performer EPS intake with a Edelbrock 600CFM 4brrl. Would these parts go well together? Any input helps kinda in over my head thanks guys!

That is a "medium" performance cam and it'll have a bit of a lope to it at idle up to about 1300-1400 rpm. Not radical by any means but not stock either. Sort of a "medium" cam.

 

Beautiful doesn't sound to radical any idea if it would be okay to put a idle-5500rpm intake on the engine with that sort of cam? It has a torker 2 on it now which is 2400-5500rpm but from what I can tell from reveiws it's not a very good intake.

Summit eBay has this kit which I seem to like has the carb I want and a closer to stock intake fairly priced ].

 

The performer intake will improve low rpm manners and the 600 carb will run fine but not make max power.
If you want a stock ride this cam will not be it.Any other mods done to the engine?

At the least recurve the distributor to get better manners.I would suspect this cam will like/tolerate a fair amount of initial advance.

 

Yeah I have it timed at 15 degrees btdc right now. But it is sending a lot of un burned gasoline out the tailpipes it has a double pumper 750 Holley on it. Don't care so much about stock as I want it to just start reliable and run good. I like the idea of a mild can if its going to work

 

Agree...The L-82 cam is .450/.460, duration 222, LSA 114

 

What do you mean by lope?

My problem is it spits and spatters when I floor it from a 700rpm idle it will even back fire though it's carb

I would say that cam is a bit hot for what you are looking for. Look at the description. It states rpm range 3000 to 6000. Intake valve closing is pretty late at 73*. That means plenty of rpms to get going and it's gonna be doggy until you get into that rpm range.
What it sounds like you want is something in the 1300 to 5300 rpm range maybe. The performer intake range is idle to 5500. That crane cam is for middle to upper rpm range performance.
Do you know the compression ratio of the engine?

This sounds like a carb tuning issue that can be tuned to run right.

 

That Crane cam is just very slightly hotter than the factory L82 cam with which your engine left the factory. It has just a tad more duration, slightly tighter lobe angle and a little more lift. In most regards, you'd have to consider the Crane cam to offer just a little better performance in the upper rpm range.

Replacing the carburetor may help, but so would sorting out what ills your engine now. I don't want to get into a an intake/carburetor fight, but the Torquer II is a good manifold. I think you are misunderstanding some of the input you're reading regarding this manifold. Many on this forum use this intake and have high regard for it. It doesn't work a lot better than the factory Quadrajet intake, but most manifolds are nearly equal (within the margin of error) until you get well above the 1hp/c.i. mark. Also, your carburetor, while you could sort it out with some deft tuning, is too big. Single plane intakes allow a cylinder to see all four venturi. A dual plane -the intake the factory put on it and also a very common aftermarket design and what you're now considering, allows a cylinder to see just two of the carburetor's venturi. A single plane on a relatively mild engine would do much better with a 600cfm carburetor. A dual plane can easily handle the 750cfm. So, my advice, if you simply must buy some parts, would be to just replace the carburetor and look at your overall tuneup.
