I recently bought an LS b18b1, and was told it was a '96. I know that the year for the head is located just above the exhaust manifold, and that reads '97. I need to know how to figure out the year for this block, I've looked all over it and found this stamp on the bottom right hand corner "PR4". Does this mean my block is not a '96? and is actually an older one? Just need some verification please, thank you.



I know it's blurry, but it does say "PR4".

 

i don't believe the year of the block is casted into it. I could be wrong though.

 

the yeah of the block should be where the headers mount. its a dial that ive seen almost every honda has this

 

Reaper, that's the head, not the block.

 

Why do you need to know ?

 

Does it have a green VIN tag riveted on the block?

If I remember correctly all 96+ Integra engines had the VIN tag riveted down on the front by the oil pan.

 

the homies h22a block has a 95 dial on it indicating its a 95 block

 

key word "H22" not B18....those engines are different

 

my f22 has it too even the jdm f22a in my other accord r.i.p had it as well
