Cylinder Heads - Cat C15, C16, C18 and 3406E

Yeah, kt, love his videos. Where is he located?

 

Kansas I believe.

 

If I win lottery, I'll get him to build me a fun motor!

 

Ok, one more time. 5ek,6ts,1lw, 5ds 40 pin ecm engines. 2ws,1mm 70 pin ecms. All these are 3406e. Model engines use same heads. Mbn,6nz, 7cz, also 70 pin ecm engines with sculptured blocks. Use same head as all previous ones listed. bxs, Mxs, nxs. Acert engines, same heads different valve springs and a few other little differences. 5ds, 1mm, 7cz have a 6.75 stroke crank. All others have 6.5 stroke crank. Acert engines have a 6.75 stroke crank but wider rod journals with 4 bolt rod caps. C18 is same block as all c-15 engines as is head. But have a 7.2 stroke crank. With larger pistons. The 5ds, 1mm, 7cz also use a larger piston but not as large as c-18. You can inter change all these cranks from a b to an acert block as some other parts.

 

Missouri.

 

If I am understanding you right, every head from a 5EK to 7cz, is the same and can be interchanged?
It is also my understanding, that they will bolt on and can be used on the acert blocks, is that correct?

Now on the cranks, are you saying that a b model crank can be interchanged with anything up to an acert block? That one is surprising, if that is the case.

 

Would a 1mm 3406e be a c15 or c16?
I bought one I know nothing about it besides that it’s a power house

 

1mm is a e-model 15.8 not called a c-16 like the 7cz but same internal assembly. Stronger block than the 7cz.

 

Yes

 

Yes and no on the cranks. Yes cranks will physically interchange as the journal sizes are the same. The gear on the snout of crank will need to match engine series. Tone rings and such for mechanical or electronic yada yada
