Compression Gain - How Much
I recently swapped out my old 081 iron heads for a set of TFS 305 heads on my Camaro. The old heads had a combustion chamber of 58cc the new heads have a 56cc chamber.
How much compression squeeze did I gain with the new (smaller) head? The factory says the motor is 9.3:1?
Just wondering...
Thanks

Re: Compression Gain - How Much
All other compression-affecting factors being equal, about 2 tenths of a point. Nothing noticeable.
