Cam info? I'm not to in tune with what the different specs on a cam mean, I did however find this in my car. I did not install this cam, it appears to be a custom grind. Can any of you give me an idea of what I have here? It's a comp cam, decent grind? Car runs pretty good just trying to learn a bit of what I have...

I don't know what the bottom end has, ill be redoing the pan gasket soon for a leak. I do have a document stating its a rebuilt short block from a 95 vette, so I'm going to assume its had lower end work..

For the power you are making the stock bottom end would be fine. Guys are laying down over 400rwhp with stock bottom end. You just can't spin it to the moon. The stock rod bolts will stretch and break.
Stock crank is far superior to an aftermarket cast crank.
Did he have a turbo or supercharger on the car?
What RPM does the car pull hard? Tight LSA creates a narrow power band, increases torque, and moves the peak torque to a lower RPM.
I bet that cam has a pretty good lope.

This is my car actually...the guy im refering to is the previous owner...no forced induction or spray. The car makes tons of power down low, but pulls decent to 6500, seems to fall off after that. It's an extremly lopey cam. The car also has full exhaust LT headers into a gutted cat on into a borla exhaust. Picked it up off craigslist for 6k. Body only has 120,000 miles on it and its a 93.

I figured it was your car but you didn't build the engine thats why I said he has them on it.
6300rpm is really the safe range of a stock bottom end.
That cam though obviously would probably max out right around that 6500 mark. But until you find out what has been done to the bottom I wouldn't push it past 6300 a lot.

I agree its likely the very old Bauer LE2 cam. There are much better cams available now. That one will be harsh on valvetrain (especially with 1.6 rockers) and I am not a big fan of 107LSA considering I just pulled a very similar cam and replaced it with something better.
You will find few guys running single pattern cams in naturally aspirated small block Chevys.
If you can feel it fall off at 6500 then it is likely the springs are worn out.
That much duration with a "bigger is better" kind of head it would likely be near/past peak at 6500 but should be slowly losing power not a sharp enough drop to feel SOTP.

Gotcha, perhaps Im not accurately describing the feel after that rpm. It by no means stops pulling just not as hard as it does prior to that engine speed. I appreciate all the info you guys have.
