What springs are you guys using for these aggressive ramps? Rates and pressures would be great (Details!). Also, what lifters as well....Thanks!

 

502 cam - CC 987's 130lbs closed,320lbs open I believe.Stock lifters.It runs great.The power band is smooth.Torque through out.

 

Thanks for the quick reply. What are you spinning your motor to?

 

I havent gone over 5800.Still have the stock limiter.I really like the cam.

 

Thanks Joe!

Like to hear from some other XE users. Especially the larger XE cams.

 

I have the XE230/236. I had the machine shop use CC987's double springs I think. The head did have to have a little machine work to allow the spring seats to work properly.

The machine shop did the heads so I know nothing about pressures or heights.

I am also using the stock lifters. I use this car mostly on the road course and it has worked perfectly so far and this runs the car at High RPM's for extended periods.

I believe they are the 987's.....it's been awhile....i know they are good to .600

 

XE 230/236
987's or 612's....haven't decided if I wanted to have the heads machined for the double springs...

 

I'm going with a 230/236 and 1.7 scorpion rollers (puts lift at .578/.589 I think). Combination Motorsports says their 612 springs are good for .600 lift so I should be fine. with them, and they are considerably less expensive than other springs I have seen

 

230/236 with 987 springs and 10° locks. Reved it to 6400, awesome torque throughout

 

224/230, CMotorsports 612 springs (good to .600), only took her to 5800 thus far

 

I have the dual Crane springs 99893 and set them up at 1.85 installed height for about 340lbs? (I can't recall for sure) open pressure. I used the Comp 850 oem replacement lifters.
