Reply to "Monster 2786 Type 4 build"

The 2.8L Type 4 is nearing completion. As with anything that has been modified my engine builder is finding issues to overcome as he goes. Being an engine with a longer stroke than stock the engine is now wider by almost an inch. Some of the issues he is dealing with include having to lengthen the push rod tubes, as is they were too short and have nothing to hold them in the head or block. He figured something out to space it on the side that goes into the head. Next issue is the DTM fan shroud. The holes for the spark plug access do not line up and will need to be enlarged on one side of each hole and filled in on the other because the heads are further out than they where. The header as it was is too narrow. It will need the spot welds ground off so the extra length can be found in the slip joint areas. Bill the engine builder has assured me that each obstacle can be overcome and made perfect ( I was glad to hear that!). He has also taken apart the rocker arm assemblies and polished the shafts and cleaned everything. The rocker arm geometry was then set using custom length pushrods. The intake gaskets had to be custom shaped to match the ported heads and intakes. The engine is mostly assembled and should be getting fired up for cam break in by the end of the week. I will be buying a new crank pulley and doing some cosmetic work once I have the engine home. I am hoping there is enough height clearance to allow the DTM fan shroud and oil cooler to fit into the Puma's engine compartment. If not I have an alternate plan to use a  lower profile version 2 DTM fan shroud and a remote oil cooler. I will hopefully have the engine home sometime next week.
