12.5:1 domed piston with Stage 2 LS6 heads that have been milled .030. what would the final compression come to? On an unmilled head that would be around 13.7:1. What would the jump be on the milled head.

I am a complete tard when it comes to trying to figure out what that kind of stuff works out to.

TIA.

 

I could figure that out if you know how many the CC's the Stage 2 LS6 heads have before milling them. It will be higher than 13.7; that sounds like too much compression unless you're going to burn race gas or alcohol.

 

Got me on that one. Let me do a little looking around

 

Well the PP site says stage 2 LS6 = 64.45cc

 

Sounds like a motor that will need to run on 110.

 

This is more or less on topic ...
A friend called last night to tell me about a (new?) Torco additive (they do not call it an octane booster) that is supposed to be the concentrated additives they use to make racing fuel. The treatment is 1 quart to 16 gallons, giving 103 from 93. 2 quarts gives 107, which they say really acts like 110. Don't quote me on the numbers, please. You can mix less also. The cost is ~$56/case of 10.

Is this old news? Anybody have any experience?

 

I dont like mixing fuels, On a high compression motor I have never wanted to risk the chance of not putting the right quantities in the mix. I'll just stick to the 55ga drum of VP.
