Black momba Jr. with 1.3 rockers?

[Mike72]

Hi guys I'm new to this forum and if someone could help me out that would be great,
I have a gx200 clone and I'm ready to install a bmj cam, and want to know if I can run 1.3 stamped rocker with 26lb springs with out any problems? Or could I run it with stock rockers and 18lds springs? I would prefer to run the 1.3
Cam is 230 dur and 275 lift

The combo of black mamba jr. And 1.3 ratio results in a very quick lift curve and 26lb springs would be marginal. You are looking at .357 lift . A black mamba sr with 26lb springs and 1.3 is fine.

Thanks for the info, Well I already have the bmj cam and need to make sure I use the right parts, right now I'm planning to buy springs and rockers and would like to know what would work best
1) 26lbs springs with 1.3 stamped rockers
2) keep stock rockers, and run 26lbs springs
3) if these options won't work what would you guys recommend
Thanks

Its a great cam and will work fine with stock rockers and 26 lb springs. If you can get the champion 1 to 1 shaft rockers they are stronger and eliminate the need for the guide plate. But are not necessary.
