ls1 ring gap for 150 shot
hello all... im in process of rebuilding a ls1, it has stock bore and pistons, has been honed for new rings. top ring is showing .025, bottom ring is showing 0.27... is this too loose or will it be ok ? the motor will see a 150 shot later down the road but will be mostly street driven. thanks too all!!!!

I did mine at that spec, but a little looser on nitrous from what I understand isn't a bad thing. I don't know what they consider mild nitrous. Me personally am going to use a 100shot. Hopefully someone with more experience can chime in.

from what ive searched i have read that a lil loose for nitrous is good but im tryin to figure out how much is too much.. i dnt want to put these in and have bad blow by or compression loss.

Since when? Ring gap depends on heat applied to rings and the force because they expand as they heat up. At least that was my understanding. I've never ordered rings and had them say ones for hyper or ones for forged.

These are the things to consider......
The machine shop that honed the block doesn't care what your doing for rings
and their gaps. They are only concerned with straightening out the bore
(minimizing taper from top to bottom) and establishing cross hatch.
The .025/.027 gaps are a tad wide but not at all rediculous.
Saying it may see 150 later can and often always turns into 250. Trust me I
know juice and if a little is good....more is better.....
Those gaps will work fine for you.
