Default Please help me find my compression!

Hey guys I just ordered a set of wiseco pro true dome pistons for a standard 364cu Lq4. Along with ls3 heads what kind of compression am I looking at?

So far here is my build

Pro true 4cc domes
823 heads
750 holly hp
Super Victor Intake
1 7/8 sw headers
Arp head / main / rods
Looking at cams

Everything else mainly stock. This is for a small 02 Sonoma. Would I be able to spray this motor? If so, how much? Thank you!

What's done to the heads, have they been milled?

Nothing but a little porting.

You'll need to know a lot more, like what head gasket you're going to use, bore x thickness and if those pistons are in or out of the hole and by how much. Then after your heads are completed, milled and assembled, you'll need to cc them. Sorry no easy answer here, do your research. Here's a good place to get your answer when you get all your data.

My heads are done just mild ported 823s. Standard 4.000 bore 3.622 stroke. +4cc dome I think it was. Just want a rough estimate. Thank you
