Ok not to thread hijack, but what if you throw the Trick Flow LT1 castings into this comparison How do they stack up?

 

Thank You all for the input thus far.

However I think I confused myself more.. initially I was thinking the small cc was a good idea for more power... but how small can you really go?

I put some figures in the compression calculator.. and I am showing that running 54cc combustion chambers on a 381 or 383 would put me around 13.1 compression. Is that too high? Granted this wont be a daily driver.. but I would like it to be more of a street/strip car than "full race/on the verge of destruction" Back to the compression calculator I am showing that 62cc chambers would put it more in the 11.5 range...

Let me know what your thoughts are on this... also what do you think of the Trick Flow 195's? - do they cool as well as the GM LT4's? I think that the combustion chambers are around 62cc on the trick flows. -- there is so much to take in to consideration.
