Engine Specs, looking for help
Hello all. I'm sure these questions have been asked a hundred or more times on here, but I cant seem to find the answers. Does anyone out there know what the stock valve-to-piston clearance is on an LO3 engine? Also, what the stock cam lift is on both Intake and Exhaust? I'm starting an engine build on my 92 (yes, building the 305. Why? Because no one else does!) and I'm looking for some baseline specs before I get too worried about cam profiling and head work. I'm sure I could find this info in some of those old books, but figured I'd start with you all first. Thanks for any help you may have!

Stock P-t-V clearance is huge. LO3 valve lift is .350/.384

Wow, I did not know that. I guess I have lots of room to work with. Thanks for the info!
