do CTR pistons fit into an LS block?

 

direct fit?
No.

 

yes ctr pistons fit in an ls block but youll have a 13:1CR with stock cams. CTR= over rated, just look cool. you get a shitty burn and they are detonation prone. im sure someone will chime in and say im wrong but whatever.

want a compression bump get p30s...you can still run pump gas.

I've never seen them with out overbore, and I know many places sell them but the stockers fit in an LS?

Also p30s work? I know US ITRs do.

 

yea...they are all 81mm bore except the b20. p30s included. they also sell them in overbore sizes as well. the issue isnt size, its compression ratio. you can run 13:1 if you want but, dont try to get your CR by raising your dome, get it by milling your head and dragging yoru valve pockets. flatter piston = better burn and less prone to detonation. you can run a piston with a big *** dome and get a super high CR but on pump gas youll have to pull a shitload of timing out of it. so whats the point? its like 2 steps foward, 1.5 steps back.

i dont mean to be a dick but i think thats a little over the OP's head.

 

LOL i'm soo smoking crack, I have p30s in mine...

it's been a long *** day, CTRs I didn't know fit though.

 

ohhhhhhh wait... im on crack as well. 9 mile hike at 230am. ghey.


you have to take 1mm off the little end of the rod. but he said fit in the BLOCK and the answer to that is YES. will they fit on LS RODS? not without taking 1mm off the lil end.

Ok moral of the story is neither of us should smoke crack

I knew it was somthing between the 2 of us we got one good anwser lol

 

Crack is bad. They do work. We used them in our 218whp B18C1, stocke= bore and stroke. But that's over this year, hoping for some 250-260 NA power.

and with a milled head and p30s and more timing it would have made 225.

that wasnt the question anyway it was "do they fit in an ls block?" the answer is yes.
