Does the extra 7 CID per cylinder yield 5% improvement in total ??? Or
is it more likely a new engine (proper compression and all that)is
responsible for the performance increase......
Is the I/O 390 an angle valve engine ? Was the 360 a parallel of angle
valve engine ??

Dana,
I put approximately 300 hours on the IO360 before converting to the
IO390.
The IO390 added approximately 5% in all parameters.
