Here is all of my involvement with the motor. I, along with Terry Spencer and Kevin Murphy, helped Bill Falcone put a new 4.0L long block into this blue 1992 RRC. Bill had told us that the long block was purchased from a company that was testing both 4.0's and 4.6's for use in marine applications. Apparently, the company was dissatisfied with the outcome of the tests on the 4.6's and sold off the unused 4.0's at bargain basement prices.
Now, to use a 4.0 block in a RRC you must change the cam. That is a given. Apparently, Bill chose a cam that was hotter than stock. I think, but am not certain the cam came from D&D and I would have expected that it would have performed fine. I also know that I saw Bill driving that truck at British by the Sea a few months after we had helped him install the motor. It was working.
I spoke with Bill briefly about a week ago and he felt that perhaps the cam was a bit too aggressive and changing it may help sort the problems out. Beyond that, I have nothing more to add to this thread.
David, I have no beef with you. I am annoyed that ANYONE would have told you there where parts valued at over $500 in the back of that green RRC. As far as it needing only alternator and a brake switch? Frankly, it looked like DAP had been using that truck to harvest parts while it was sitting in their lot and what WAS in the back qualified as trash for the junkyard. Sell it for scrap and be done with it.
