I did not physically check when assembling the engine. When I asked Texas speed they said it was 11.7-1 with Lt1 heads and block. I said oh so it's higher than stock and they said no, when we've checked the factory stuff it's actually 11.9-1 so this is a little lower than stock. So that's what I went with. Heads have never been decked and its using stock head gaskets. I've felt like I should be able to run more timing but after spinning a rod bearing I've been trying to be cautious with the new setup. 22 degrees and 11.5lbs of boost definitely sounds like a good time though!
