cam?
How can I tell if I have an engine without the stock cam in it? Can I yank off the valve covers and do some measurements?
I can rev the thing up to 5200rpm but am too chicken to go any further, mainly from the noise. The things jumps to 4500 in an instant. As far as I know it's a '65 <a href="http://www.motorhaven.com/">390 </a>and the only thing I have done is put on a <a href="http://www.motorhaven.com/">Holley</a> 750 and an electronic ignition. I beleive I did a little bit of smoothing to the exhaust passeges, but it still has the log manifolds, 2" pipe to two cherry bombs cut off just passed the cab (shorter cab than your's). I only remeber that the heads end with R and begin with C5.
What's the natural rpm limit of a '65 <a href="http://www.motorhaven.com/">390 </a>anyway?

Nope, with hydraulic lifters when you rotate the engine by hand the lifters compress making it almost impossible to measure valve lift. My 360 had a stock cam and got up to 4,500 pretty fast. That is in neutral anyway. A stock 65 <a href="http://www.motorhaven.com/">390 </a>could have a number of different performance levels as if you have a 65 <a href="http://www.motorhaven.com/">390 </a>it came out of a car. I think the <a href="http://www.motorhaven.com/">352 </a>was the only FE in 65 trucks.

Ya, I figured that it was a car motor. I bought the thing as a 360 pulled out of a '70 pickup. I knew it wasn't a '70 or a 360 by the numbers, and the stroke was too long afor a 352. But I guess that the cam is more than likely normal anyways. Thanks.
