N14 Block 855 build.

Greetings from Australia.
I was searching the forum and found one year old thread. Figured id start my own.
I am undertaking a full rebuild of a 745 cpl ntc 855 Big Cam ( pretty standard cpl here)

So the engine shop has told me the block is WAYYY below the spec to skim the deck. Even is i did use a .010 gasket. So thats an anchor.

My question is this, I have a fully machined N14 block ready to go.
Same liners, same cam bearings, same everything almost.
Even the block height is the same. Squirters different... cant see that being a problem.
I saw another member say... Machining is needed. So if someone know what the machining requirements are?? that would be greatly appreciated.
Thanks again if you got this far.

 

I am aware of the helical vs straight gears.
So if i use all the big cam parts,
Then I shouldn’t have a problem there.
Bc3 blocks are getting harder to find. and i have this block available. I am hoping it will work.

 

My nt855 parts have the helical gears.
I stripped out a complete non stc 444.
So i have all of the associated parts.

i am really just hoping the heights and crank Will physically fit.
Thanks for the assistance

 

Are the valves the only problem?
I found the 444 pistons have a deeper valve recess and the same comp ratio.

will the crank physically not fit?
Or the valves are the issue. A 855 liner and a n14 liner are the same. 3055099.

 

Ohh right. now that’s a major bummer.

Thankyou for clearing that up.
