Cam
Dan,
If you want a solid roller -something in the 288 or 292 XR series will get you in the ballpark. For specific results I 'd call Comp cams free tech line, they have a computer program with thousands of combo's. Good Luck, Perry.:cool: |
Cam specs are largly determined by the RPM's you plan to run. 385's thrive on lift and low compression, so 10/1 static compression and a .65 lift roller will give you a bottom end rpm around around 2500 in the powerband with most aftermarket heads. Move up the powerband about 600rpms for each .5 lift gain you put into the cam. You can run more overlap (lobe center) plus more lift into the cam if you increase compression and run race gas. 385's generally have about the same horsepower if all things are equal regardless of displacement, but as you add stroke to them(and displacement) the powerband moves down lower and the torque rises slightly. Big cubers seem to respond to longer durations on the exaust side of the cam too. So with 11/1 compression and those stockish iron heads it looks like about a .7 to .72 lift cam is about right. I would give it a cam with about 6 to 8 degrees more on the exaust side, and set it in straight up. You can always advance or retard the cam to bring it into your driving style later. If you go to a .75 lift cam then loose the 6 to 8 degree idea, but I think it would be too much. That 11/1 compression is the equilivant to 12/1 compression with aluminum heads, so unless you did lots of chamber work on those heads you will have to run race gas too. I'd also bet those heads will start to choke off at around 6500 rpms too. So running any cam past .75 lift would be counter productive for sure. Have fun in the mud.
