This is an area that I know the hows and why's but have never done it. The guy that did the machine work on my motor and the dyno pulls used to be a crew chief for both an IMSA car and a Busch team that used the Stage II Buick V6. He told me that I'd gain right around 20 horsepower but I never asked him about the details. If you don't mind tell me what kind of vacuum breaks you use and are they adjustable. I've heard you can pull the seals into a motor if you get too much but that could be "talk".

I appreciate the info as I HATE to screw something up. And certainly don't mind learning something new from someone who knows.

Regards,
