not sure what the exact specs are but its around a 228 or something similar ill ask next visit, ill try to get a recording of it idling. It ended up getting vavle springs, dual timing chain, 25% under drive pulley, hardened pushrods and new gaskets along with the rest of the package. Car apparently had a exhaust leak and now thats fixed it and cam added it has changed the sound completely and has a very metallic sound (lol thats what it sounds like). So in other words im happy in how it came up haha
