I suspect your Hilborn "butterflys", measure 1.8" dia. ? If so, same as mine. Mine has Hilborn pump and water pump driven, direct by cam. I was at Hilborn, in Laguna Niguel, when they were building the "last" shipment of (50), to Azland. GM,Buick and Olds, did some real odd-ball motors/parts for the Indy efforts. Unless you're a quite skilled corner burner/etc., you may find some challenges with Hilborns, on the street,(loading-up on low speeds). Story I was told, was use a excess fuel return tank, clos as possible to engine bay, (reduce load-up). Looks like a handful and fun. Good Luck, roverman.

Is there a timing belt set up available for these engines( instead of a chain)?

Had the engine running today, plan was to get it warm and full of water so I can set the fan controller. It was going well at first, nice oil pressure, steady idle, etc. then I noticed I was putting more water in then the engine should hold. Checked the oil and there is water in it, hopefully I shut it off before any bearing damage but Iím wondering if I have bad head gasket or something else. The block had a crack on the outside that leaked water, wondering if there is a crack inside.

I picked up a rover 4.2 hoping to only use the shortblock. Will all the parts from my 3.5 bolt on? I know a ton of parts interchange but am unsure about the flywheel. I literally want to only use the bare block and rotating assembly and swap the rest from my 215.

Like a Jessel Belt Drive? They are quite pricey. Doubt they are available for the 215.

Yes like Jessel, or any other manufacturer.

I did some searching but I couldnít find the answer. Wondering what the piston dish volume is on the 4.2 motors?
