Ok guys, got a bit of turmoil going on in my head. Had my engine all planned out and had the cam picked and everything, it was time to start getting parts. Figured I would be using a hydraulic flat tappet from crane cams. This being my first build and all, I tend to keep pouring over the info I can find online and in books. Basically online the word is that flat tappets are failing a lot more and that the newer oils cannot keep them going, and they tend to flatten out. Thus making the roller cams more reliable and longer lasting.
The cost difference between the 2 is quite a bit and the reasoning is obvious. I'm just wondering if I got a hydraulic flat tappet if that would work fine, and there is no need for a roller. Figured rather than getting my answers from other random websites and places advertising their goods, I should ask the folks on here that know.
Anyways both cams would be similar, about .500 lift 112 lsa 230/240 duration (all averaged numbers nothing specific). The big thing is the reliability, because when it comes right down to it I do drive my car at least a few days a week, weather permitting.
