RE: tunnelport engine

By Travis Miller - 03/06/2001 8:27:45 PM; IP 205.188.192.53

If you put the 428 crank in, you will bring the torque range down below the RPMs where the heads are designed to flow best. Is it a true tunnelport engine or is it a medium riser with a tunnelwedge intake.

At any rate you want to replace the sodium filled exhaust valves. A little history is in order here. Big trucks first used sodium filled exhaust valves and hardened seats in the head because of the extreme pressures put on the valves when lugging the engines pulling heavy loads. If an engine with sodium filled valves is used everyday or so, the valves will last forever. But if the valves do not get heated up periodically, the sodium will eventually eat the valve from the inside out and the spring pressure will pop the head off the valve. There have been cases where a sodium filled valve has popped the head off with the heads stored off the engine.

If this engine has been setting 10 years with sodium filled exhaust valves, replace them with SS ones before you start the engine. A dropped valve can really ruin your day.

This thread, so far...
