As far as the rest I'd try and stay between 108 to 114 valve separation for the street as this will give better driveability, better idle and better low end torque. I think this is the maximum you'd want to go with the OE cast pistons. If it were me, I'd flycut them anyway if you are going this high. 498 lift without having to flycut the pistons. With stock cast pistons I believe you can go with a. Sorry I got carried away in my first post.Īgain, what work has been done to rotating assembly?

The 289/271 HP had hand picked cranks and they were Brinnel tested. In the old days we used the pin them.we did a lot of crazy things back then.50 years ago. My question is this a real 289 HiPro? If it is it's sure worth a lot more than what you paid for the car! If you are just talking a garden variety 289 C code the OE heads are on the weak side as they have pressed in rocker studs and come out with higher lift cams and anything above 6000 rpm. 460 lift and 310 duration.and not meant to spin more than 6000 rpm. With this information I think people could suggest a cam.the original hipro cam was in the. Did you buy new pistons, use ARP rod and main bolts/studs and what heads are on the car and what did you do to them. What have you done to the motor and what machine work have you had done.
