Default Do I have a cam?

Silly question I know, but when you are buying a car it's always 10x more amazing than anything else according to the seller. I already knew half the things being told to me where BS, but I'm wondering if the part about a mild cam is true. I've already researched my block and heads, but I can't just pop off a cover to check the cam as we all know.

So opinions please. It's been since 2004 since I've personally owned a V8 and I really am not sure if this is how a normal stock 350 should cam or not.

Was taken with my iphone, so not the most amazing sound quality I know.

I would say yes....just by the nice little lope the engine has at idle. Nice tone
Congrats on the new C3

If you find some excuse to have to do the timing chain, then you can look at the face of the cam and know for sure.

After watching the video, it just seems to me like it has a low idle, but doesnt necessarily mean that its stock. Where does the motor seem to run out of steam?

I should mention the car has a Holly 4 barrel carb, elderbrock intake, long tube headers and full exhaust with x pipe cross over. So not totally stock.

It does seem to have a good amount of power and I'd say it runs out of steam at about 5500rpm

For a 3 speed I am pretty impressed with how well it pulls when cruising at 55mph all the way to 85mph. Engine feels like it has some stout to it.

5500 rpms sounds beyond the reach of a stock cam

That could explain some of the serious pep. I'm not complaining. Car seems to run well on 89 and above and ran pretty crap-tasic when I tried 87 octane.

You can actually pop off a cover and check cam lift. Take the valve cover off and set up a dial indicator on the tip of the bulge in the rocker arm where the push rod sits. Measure the difference between open and closed. Then multiply by. 1.5. (rocker arm ratio) This will be gross valve lift. (My guess is about .44-something)

If it runs, it most certainly has a cam in it.

Hold on, where is my sign.

So I suppose the appropriate question should have been, is it possible I have an aftermarket cam. :p

Maybe it's the elusive "3/4" cam that every seller says he installed just last month.

Crane used to market a couple of cams as 3/4 race cams. The merchandise narrative said "Rumpety Rump idle and fantastic horsepower!"

Back in 1997 I threw one in a 305 H/O in an 84 Z28, and my friends constantly quoted the above statement.

Nothing was more amusing to me than one guy whose vette I looked at that was advertised as having a "Corvette Engine" as opposed to..... ?? ... a Mustang engine, I dunno.

The "corvette engine" is one of my favorite topics. Naturally a Corvette should have one, but given all of the cars out there that the owner's claim have a "corvette engine" in it, I cant imagine how many Corvette's are out there, stripped of their original engine for that reason.
