Hey guys,
I'm sure some of you read my thread a few weeks back on trying to figure out what cam to run in my 327 build. I've decided to run the Elgin Industries oem grind of the 30-30.
Here is my question on a little different of a subject though. I have a fresh 2-3k mile 327 short block (standard bore) that I am using for my build. It came out of a 300hp 327 67' Corvette. The casting number is V0626HE. I've ran the casting numbers and such through the GM books and I'm getting mixed information. I want to know what compression ratio I should expect running my '461' camel hump heads? I'm just going to assume that my heads haven't been milled and are a standard 64cc.
I've seen that the compression with this short block with 64cc heads is anywhere from 10.0:1 to 10.5:1. I know it's not a huge deal but I'd like to see if anyone knows something I don't? I'd like to keep my compression above 10.0:1 if at all possible.
I've also read that the internals in this short block from the factory used a steel forged crank, forged rods, and forged pistons?
Here are some pics for reference.
