I took a video of the exhaust because I have no idea what cam it is and was hoping someone could guess? Is this why my mog is terrible?

Again I bought the car and I have no idea what it has other than the moot or was rebuilt.

realy hard to tell what size the cam is by the sound out the exhaust .. when i do is i need to lay my hand on the air cleaner when the engine is running... but more numbers the better like vacuum at idle . a lower dollar cam kit and check valve springs and over all engine shape then recam it. the 305 may not be the best but far from worst yep a 350 or 383 may be better but there were a hell of a lot of the smaller 283 out there pulling big old chevys and boats . 350 or 383 not going to get better fuel MPG if your foot down in it

That's it guys, I've been told it sounds like a 30-30 cam or more but I have no idea and people keep asking me. I thought it was stick until people said it sounded better than a 305
