nice sneakers!! thing about the rtc-6 is not only the bigger valves, but the head casting overall....nice big runners that only need to be touched to clean up the sharp edges and the shape of the chamber is also good...it actually looks smaller than the rtc-4 shown...i haven't pulled the other rtc-6 off the stock engine yet, but when i do i'll get a pic and post it, unless someone else has one....
bottom line is that i like the direction that the predator engines is going...just wish that they would do us all a favor and couple the rtc-6 head with the hemi bottom end! that would be a great motor....
one question that i have....has anyone checked the "in-da-hole" on the hemi? i am trying to figure out if a 20 over rod would put me too high or right at near zero deck height.....i know that all engines may be different, but jsut want to know opinions.....
