BruceBowker Posted April 20, 2009 Share Posted April 20, 2009 I am thinking about putting roller rockers on my Seven. It has a 1600 Ford Crossflow. Any suggestions where one can buy the necessary parts? Thanks Bruce Link to comment Share on other sites More sharing options...
locost7018 Posted April 20, 2009 Share Posted April 20, 2009 Look at Burton Power out of the UK. Russ Link to comment Share on other sites More sharing options...
bball7754 Posted April 21, 2009 Share Posted April 21, 2009 Another option would be Dave Bean here in the US. They're listed in my copy of the English Ford Racers Catalog. Steve Link to comment Share on other sites More sharing options...
BruceBowker Posted April 21, 2009 Author Share Posted April 21, 2009 I suppose an even more important question is - is it worth the money? Will I see any reasonable power increase or other advantage? Bruce Link to comment Share on other sites More sharing options...
Al N. Posted April 21, 2009 Share Posted April 21, 2009 Bruce, I saw that Tony V. is parting out not one but two crossflows...one is Jay Ivey built/tuned. So you might want to reach out to him and buy one of those for the basis of a hot motor. According to Ted Wenz of MWE, you can get 145 out of a reasonably reliable crossflow stroker.

JohnCh Posted April 21, 2009 Share Posted April 21, 2009 I suppose an even more important question is - is it worth the money? Will I see any reasonable power increase or other advantage? I looked into this when I had a crossflow powered car and was told by one of the top crossflow tuners in the UK, that money is best spent elsewhere. He was a big advocate of a programmable 3D ignition system. According to him benefits were twofold: Significantly better mpg. Although that's not why we buy these cars, it does mean you have longer touring range Much better driveability. He said that an engine with a Kent 244 and 3d ignition has better driveability than an engine running the milder 234 cam. -John Link to comment Share on other sites More sharing options...
bball7754 Posted April 21, 2009 Share Posted April 21, 2009 Although my 1700 Xflow with 244 cam has the roller rockers, my reading on Blatchat supports John's view. Roger King (UK Xflow guru) actually seems to have negative views of the roller rockers, and seems to prefer the standard valve train for highly tuned Xflow's. There seem to be many happy UK Xflow owners who have added the 3d ignition. Steve Link to comment Share on other sites More sharing options...
southwind25 Posted April 21, 2009 Share Posted April 21, 2009 Roller rockers.. when i first got our car, i had to replace one of the rockers because the adj. screw was stripped. I was looking into the roller type to just replace them all. Really nice..but probably the last modification i would do to the engine all said and done if i had money left over..which i never do.

Kitcat Posted April 21, 2009 Share Posted April 21, 2009 Steve: Are you using 3d ignition? I have a vague memory that you are. If so, do you like it? Has gas mileage improved? (I get 10-14 around town, 18-20 on the highway). I know you are making more power than I am, but your hotter cam may explain that somewhat.

lowflyer Posted April 21, 2009 Share Posted April 21, 2009 re: the use of "standard rockers" If you're planning on running the engine in the 7000 rpm range you will need to replace the standard rockers and stands with machined steel ones, instead of the cast iron stock pieces. The rocker shafts and stands will actually deflect with the heavier springs and higher rpms. Don't ask me how I know this. Link to comment Share on other sites More sharing options...
bball7754 Posted April 22, 2009 Share Posted April 22, 2009 Mike - Unfortunately, just electronic ignition (no points) but no 3d. I think the cam does help. Believe my engine started life as the 135 HP spec, and later had the cam change. Steve Link to comment Share on other sites More sharing options...
BruceBowker Posted April 22, 2009 Author Share Posted April 22, 2009 Thanks all. I think I will abandon this idea and look to other options. Thanks again Link to comment Share on other sites More sharing options...
