Broken valve spring

You could get a 5.3 core block and have it bored to 5.7 and then put all the LS1 parts in it.

Hmmmm... I think Dale has a 5.3L block just laying around. How convenient! :thumb:

I used to read a whole lot of manuals. Now its just worthless information consuming space in my small mind.

True that!

damm dale,that sux bro,hope you get all these problems worked out.

getting all 8 cylinders bored and honed to 5.7L dimensions is the cheapest mod you can do to build hp on a 5.3L engine. Added benefit is you only need one piston/rod assembly to finish the build. :thumb: Getting it balanced would be great, too. Maybe Xtreme can bore and balance it for you.

LS1 aluminum 5.7L motors can be bored out to .010--nothing more. The block thickness cannot handle more than .010. But you can bore it out and re-sleeve it...back to a 5.7L displacement.
