Anyone know? I need to swap the short block and was wondering if I can use a 2006 engine in my 2005? maybe they made improvements? Will the sensors/senders still work?

I don't want to go pull it out only to find out it isn't compatible.

Differentil pump(rockauto says same), starter(rockauto shows different!), flex plate, transmission(dont care), torque converter(dont care), water pump, thermostat housing....

Same: Oil pan, oil pressure switch, oil pickup, cylinder head is 05-07, head gasket(01-07), timing 03-06, exhaust manifold(04-08), intake 05-07,cam(05-07), intake valve 2000-2009, crank damper(2000-2009), crank(05-08).
flexplate(04-09), rod bearing(05-09). piston assembly(04-07), engine mount, air temp sensor(01-09), cam sensor(04-06), crank sensor(02-07), oil pressure switch(03-06), radiator(04-06)

Oil pump doesnt scare me... The starter, flexplate does... But crank is the same so it should take the 05 flexplate and starter then? Rock auto

MIke:
Are you talking about the 5.7L here? One big difference is that the 06 5.7 will have MDS cylinder shutdown, whereas your 05 does not. IIRC, there may be a Ram truck engine in the same range without MDS that could work. Have you considered rebuilding the '05, or is that not an option due to damage?

sorry 4.7, I did accidentally pick up a good 5.7 but I cant swap it out due to sheer amount of headache. This 05 is locked up, crank/block ruined.
I'm eyeballing a 06 4.7 SLT in the pull yard. It has great compression and ill cut open the oil filter/check the oil in the pan.
