so to my understanding the sensors should all be the same on the block? minus the one i have to drill and tap(i think it is for a 2.5 sensor to fit the 3L block). and another thing well two things which hoses normally wear(sp) the most and are recomended for changing? i am going to try and use all the bolt on pieces(accessories) that are in the car...A/C comp, alt, power steering pump... this is correct right i did notice how the blocks are almost identical its nucking futs i did come to a problem last night though the accessory pully and harmonic balancer do i need to use the 2.5 pully and get the DMD or should i use the HB off the 3L with the 2.5 pully there are a lot of combinations i will read i promise but i thought id throw the question out there. this is really becoming fun...
