Im sure 146hp is a great number and besides making sure future rods
dont let go by using better conrods you might look into something
similar in what Lemonhead has done and go for 83mm ca18de pistons
this time by offset boring 2/3 and sleeving 1/4.
CA18de pistons need about .5mm off them to make them flatops
and you would best try to duplicate some of the best Active
chamber designs on current corvette 600+hp heads for good tumble
and swirl all in one. I can imagine an extra 200cc would be enough
on what you had already though.
