I just picked up cub cylinders for a price i couldnt refuse so my passion 4mill cyinders are for sale. They are .20 over, 12 port, Nice polish job on them. No more than 5 hours on bore and pistons (which are included), you can still see the cross hatching. These cylinders pull hard! Jim at passion does some bad ass work! And has helped greatly to get these cylinders tuned in, these will make about 85 horse on race gas if tuned properly. No disapointments! $600 shipped. Feel free to ask questions

so these cylinders are triple exhaust ported? email me at [email protected]

E mail sent. 12 port passion cylinders have 2 additional finger ports installed on each side of main intake ports and 2 window ports machined into liners. This requires tig welding around both rear stud areas.

Just to clarify. passion 12 port is NOT a tripple exhaust. Still a stout motor though.
