The block looks brand new to me. The enginenumber is XM46D305L25. Does anybody know where that number comes from? It seems not to be a rover number. Enclosed I am sending some pictures. It has the standard liners. Should I give the a try or are they going to slip instantly? The plan is to run the engine with a 75°C thermostat.
The heads look also like new but seem to be ported.
The two cams gave some numbers on them. Can anybody recognize from the numbers what sort of cams they are?
I want to build 4x4 engine, so not looking for extreme tuning. I am not even shure, if I should rather go for standard heads for my application.
I am sure there will be more questions coming when I start, so thank you in advance for all the help.
Your project is definitely doable.
Presumably you want the original front cover on the engine with distributor, so there are a few nuances with doing that as the crank nose is a bit longer.
The original liners are not a definite problem - mine lasted 100,000 miles before letting go. Depends on budget, and botheration, but I always get mine top hat linered when building an engine as it's easier to do it then and forget about it.
The 4.6 engine is on the limit (if not a bit over) in terms of exceeding capacity of the SU's ability to flow.
