I've never had a cooling issue with this truck. You can 3/4 fill a 7.3 (if done correctly) you won't have any cooling issue as the heat build up in these engines happens prodominantly in the top 2" of the cylinder.
The passages have to be predetermined so coolant can still reach the oil...
Carson StaufFer Built the motor.
I Was running a 476/96 and it loved that turbo only problem was the smoke of the 450's lol
I'm thinking around $9500 for the long block if I split it up
The HPOPs are the only thing not replaced when I put the engine in it has about 150 miles ago this truck has been almost all track use(drove to track a few times). Put it in the end of the season before last so roughly a season and a half of racing on it.
