| 390 reliability |
| By Troy - 02/19/2005 4:53:01 PM; IP 64.5.237.252 |
| I currently run a 390 in my pulling/mud bog truck. It has 4.10 gears and a four speed. My cam of choice is a comp cams 292 hyd,heads are C1AE castings with 2.09/1.66 valves.Bottom end is mostly stock(arp bolts),rarely turn more than 6000 rpm,but I am on my third motor. All have broke the rod at #6 cylinder.Is this a weak area or just a bad coincidence.All advice or theories welcome. |
