[Formula8]

Wow. I have been buried at work and been off line for a couple of days and my email is packed with notifications! Anyway, thanks Paul, Dave, Tom, Steve, Darby and everyone else that contributed to this thread. The subject has bounced around a bit but lots of great info.

For me, I ran my SD/KRE heads with my SFT cam and it was everything I ever wanted. For whatever the reason, It was clear my iron heads were leaving some serious power and driveability on the table so they were sold and I have absolutely no regrets about that decision. Well...... outside of I should have reinstalled by rev limiter. My SFT cam quickly was showing signs of going flat under the increased spring pressure used with these heads so I needed to replace a cam and lifters anyway. Yes, I used VR1 with either EOS or ZDDP. Even so, it makes little sense to mess with the flat tappet stuff nowadays so I made the decision to go roller and the OF is a proven cam in many similar combinations.

Given that my block is not fitted with oil restrictors and I was hoping to retain the new pushrods I bought when I installed the KREs, I thought a lifter that provided oil restriction, pin oiling and relative to most hydraulic lifters, seems to be quietly and reliably going about their business in many engines would be a good choice for my application. I prefer solid lifters as there is no monkey business over the preload so Crower's 66260H was chosen as it meets all the criteria and does not break the bank.

Soooo.....that is how I arrive at an aluminum KRE/SD D-port, OF cam and Crower solid lifter being the best solution for my situation and car. I would certainly hope that a dedicated drag car could absolutely walk around my car with iron head and a HFT cam. But. I am not interested in a drag car, working over 40 year old iron heads or playing chemist with oil to keep the cam alive. So, I think this combo will suit my needs in a easy to deal with package like Dave suggests.
