Hi i´m wondering what you guys think has been done to this 318 based on the sound.

((Warning the video is really loud))

Here´s the story when i bought the car the motor was already in it but the previous owner had bought the motor of someone else and didn't really know anything about it other than it had recently been rebuilt.
Here´s what i have found out looking at the motor it´s a 76 318 block with 596 heads and what looks like these valve springs http://www.jegs.com/i/Mopar-Performance/312/P4120249/10002/-1?parentProductId=746993 a stock 360 fourbarrel intake and a quadrajet and open manifolds.

So here´s my question do think this thing has a bigger than stock cam and do think the heads have been shaved, i´m asking this because it seems to rev up faster than a motor with really low compression.

Sounds like a stock 318 with open manifolds.
 
Yeah that´s what i thought, the p.o said it might have a bigger cam but it sounds stock to me then when i saw the valve springs i thought he might be right. At least i wont have to buy new springs:cheers: Thanks guys.
 
I bet it's been videoed and posted on the internet....
