Has anyone tried roller lifters in a type 4, or any flat motor?

I just got done with a 2056 build, following 2 years of research and tear down.
Having an extensive background building GM small and Big blocks, I was very interested in roller rockers and or followers when considering my Type 4 build. As I discovered, the only 'available' roller rockers were the Pauter, and the general consensus was 1 they are really best used in all out racing applications, 2. They break, 3 they are very expensive. I also found that solid lifters, a performance grind on a cam, modified 1.7 rockers, custom length chrome moly pushrods and swivel foot adjusters are just about the best way to go, especially for the DIY'r. Now where did I get that info? YUP, largely all of the above is RABY developed. ANd I didn't steal it, it was shared and written about. So any accusation that RAT does not share proprietary info is total BS. Jake, thanks for sharing what you have developed and innovated. I'm sure that much of your cutting edge and new/leading developments are proprietary and you need to guard some of this info. You are a businessman, and enthusiast. and yep, to many you are a jerk, but your a Marine Aviator.... NUF SAID. Hooah - - Oorah - - I'd love to try Ceramic lifters or Roller Rockers, and hope that the marked pushes someone to develop something, but I doubt that will happen. |

I'm sure he'll correct me if I'm wrong, but I think all those things originally came from the T1 world and were used by other T4 builders, mostly DIY'ers, before Jake. You can search the Shoptalk Forums for the history of each of those (and Usenet RAMVA before that). There were a lot more people involved back then, and information was shared more freely than it is now. |

I'm all for sharing info, I guess since I don't make a living from the parts I've made it is no big deal to share. For the Volvo guys I've publicly released the following 3 engineer drawings of parts I've made: Redbook engine to GM auto transmission (upright version), Volvo whiteblock to Ford T5 adapter and and Hall sensor adapter to replace the VR sensor. I figure one of these days I'll see an ad from someone selling "my" parts, as long as I don't get an email asking for support, no big deal to me. Back to the rollers, hope to meet a RAT roller equipped owner one of theses days to get a ride and be further inspired. |
