Engine damage / 440 RB
I am not getting these oil lines in the valley ? To me that is taking oil away from bearings where Mopar needs it the most . We put restrictors in the rocker arm lines to cut back the oil going there. Chevys love oil in rockers. Mopar love oil in bearings, lots of good oil !
I am just refreshing a 496 wedge after 6 years on the street and strip. This motor has hundreds of passes on it. The reason for refresh is it cracked a sleeve when a head gasket leaked and number two hydraulic locked.This motor was spec'd out by Dave Hughes of Hughes Engine. It is 13.4 CR running on pump gas 94 octane with no additives and 32 degrees timing. Dyno 735 hp 700 torque. Crank is mint condition,rods and Pistons going back in.New oil pump,rings,all bearings and one new sleeve.We only use Domar oil filters sold by Hughes Engines. They have No Relief Valve ! All other filters have relief valve which on cold start up Cold oil temp. Pushes valve open and all the unfiltered oil goes straight into the main bearings,rod bearings then on to the rest of motor. My current motor is a 572 wedge going into 3rd year is getting valves adjusted and fresh Joe Gibbs oil that's it. If you go to Clevite bearings web site they will show pictures of failed bearings ans have a write up of causes. Very interesting !
