[08z51c6]

Looking at doing some mods to my SS in the future, in the planning stages now.

Considering the following mods:

1. Rotofab CAI
2. EFI Tuning ported throttle body and intake manifold
3. GM heads and cam kit
4. Hooker Black Heart shorty headers
5. Flowmaster mid pipe
6. EFI Tuning Flex Fuel kit

Wondering how much power the above mods would make and at what cost? I know the GM heads and cam kit is supposed to be rated around 535hp (crank) but the throttle body, manifold, and Flex Fuel should increase that number.

Also with the Flex Fuel kit can I run regular 93 octane and then E85 occasionally or do you need to run E85 all the time?

Thoughts, suggestions, advice???
