Does anyone know for sure(meaning you saw it with your own eyes) what the piston to deck height is for ctr pistons in a b18c block?

There all going to differ slightly depending on how accurate your tools are.. generally oem pistons are "in the deck" a several thousands, depending if the deck has been milled.. use a depth checker and then you will know for sure.. ..

 

typically CTR pistons sit at the deck or above the deck

The point in me asking was to find out where they sit before I buy them and put them in a block. But thanks anyway

 

You can if you know the compression height of the piston and the rod length.

thats kinda scary, some reason i think p30 pistons may suite better

I tried it that way and came up with .0085" of piston-to-deck clearance. When I actually measured, it came up to .000" (depending on what side of the piston you measured). Then again, some of the numbers I used in the calculations might not have been as accurate as I had assumed.

 

I would post my pics of my block when I had ctr's! they make power in b series blocks! just don't miss shift! and you will be happy alot fo my friends setups were like that a while back. you will like them like I did!

but to answer your question it all depends if the block was ever decked and whether your head was milled to be very accurate

 

If the deck wasn't the same then it might be a good idea to deck the block to get it squared up.

 

i have ctr pistons and don't know if it's a good idea to put them in when the deck clearance is close for stock head not milled.
