a 440 from this year would be liquid and have the valves so that wont work

[quote=“mgmid7070,post:7,topic:37813"”]

see if it has variable exhaust valves(I think that was a 440 fan and it would not have any variable exhaust valves), I don’t know why he would put a Liquid cooled motor into a 440, the heat exchangers would cost more then the motor, I thought about it about 2 years ago for a 500sle.
