I was going to swap to the newer chasis just dont have the timeOn Apr-29-15 at 17:20:31 PDT. seller added the following information:Some items that need to be addressed are the hydroboost leaks but the the donor truck has a good one. I never got the motor dialed in after installing it. It has a new battery . lternator & distributor. At high rpm under load it seems like its starving for fuel. I was going to add an inline fuel pump just never got to it.
