Default 396 Build Up

This might sound like a dumb question but can a 396 2-bolt main running on pump gas with a solid roller cam get into the 11's without any power adders?

What I am contemplating on building is a 1971 854 CE block with the pistons that were in my motor then using 077 aluminum heads with a solid roller.

Here are a couple of pictures of the pistons.

Have you c.c'ed the chambers on your 077's?

Do you already have a cam picked out?

Open chamber heads on those pistons are going to throw 1 full point plus of compression out the window, which isn't necessarily a bad thing since you're wanting to run pump gas, but you'll have to be very careful with the cam specs to keep cylinder pressure in line.

I was on Team Chevelle and one of the guys there had it figured out that if I run these exact pistons with 077 (118cc) I would be at about 10.37 compression.

I totally missed the part # on the pistons...was thinking of the factory 11-1 pistons.

Those should work OK, just check to make sure there's no dome-to-chamber interference issues.

What about the rest of the combination?
