First of all, any gap between the cylinder walls and pistons (rings I will assume you meant) is bad. If the gap is big enough that you can see it with your own eyes, thennnnn... it is perfect! good job cant wait to see the startup vid. I suggest the whole start over from scratch method as previously mentioned in this thead. At least you got a head start on boring her out!

 

Its not free hand i used a tape measure

And I can barley see the gap so i shouldnt loose hardley any compression. Tommrow im gonna finish reinstalling everything, and on wedsneday the motor goes back in my camaro

My friend bored is own block, but he had some expensive machine to do it. I just watched the machine and did the same thing with the dremel.

 

this is a joke. fuck off

 

This guy can't even tell a convincing joke. An LS1 stock bore is 3.89X and the max you can bore them is around .010. I don't think the external diameter of the cylinder sleeve is even 4.125".

thats not true. I dont remember the number, but you can bore an LS1 max to a 454. I'm positive about that. Do the reverse calc and youll find the number. I have it here in a book somewhere.

 

Dial caliper > tape measure

 

No, the max you can bore a stock ls1 is .010. You can resleeve and stroke and I think mti has ended up with a 455 so far. There's supposed to be a new iron block coming out that you can take up to 480ci and with the new l92 parts coming out its going to be cheap to build a big motor.

 

Holy shit I wanna see this. I hope for my whole life, that this guy is serious.

 

i hope you step on a nail today...right through your foot.
