Stud Mount Conversion Kits
#22
I have the Crane conversion kit on my F150 with a 358ci engine with p-heads. It sees 5500rpm quite a bit (it's a mud truck). They've been on it for 4 years, and not one problem. I wouldn't use them if you plan to spin it over 6000, but under that, you'll be fine.

I know this is a old thread, However, I am running trick Flow heads with pedestal mount roller and once my car gets to 5500 rpms it craps out. my valves are floating.
It has been this way since I installed these heads. My cam lift is .538 any idea why this could be happening?
I dont see any wear and the rollers set right on the valves. I have one roller that is a little loose so i am going to re shim it. Other than that is this to be expected?
I was hoping to get it to 6200 where my limiter is set.

lift means nothing.......it's all on what lobe profile is on the cam, the ramp rates and or how aggressive they are that determine what springs should be used and how much closed pressure and open pressure there should be......what is the powerband of the cam?? if you have not tested the current springs rate, open vs closed pressure and compared them to cam specs then you need to do such......and please don't say but tfs says springs are good to xxx lift, I junk the factory springs right away when they come on new aftermarket heads, cause they are mass produced weak crap
