If you have a high octane gas available, those low-C pistons gotta go!
Or you could bolt on a closed chamber teener top end and cam, and make a tow-truck engine out of it. :)
Just speaking to some of our local engine builders and they reckon to aim for 9.5 compression for the street to run on our shitty 96 octane.So yeah looks like they could be made to exit stage right
