Crate 3.4L vs 95 Lumina LS

As long as you use the coorect pistons with the heads, you will yield a "stock" CR for that engine. You said you had a donor motor for parts?

It's true!

But if I can avoid pulling apart my bottom end, I will :P (It's only got 10K on it)

I wouldn't mind getting a C/R closer to 10:1, but anything over that is a bit much for my purposes.

Well, using the site's CR calculator I figure that with a 4mm head gasket, I'd have the CR in a good place.

Anyone make one? That would be too convenient though . . .

That's .158" ! .060/.040 are stock sizes. If you have that much gasket, your quench would be really high. Most people strive for .040 quench.
