Going solid roller

[astglenn]

Well I just ordered my Crower solid roller cam, shaft rockers and valve springs. I believe I will get more efficiency, better snap, more power everywhere and sick of valve adjusting for the effort. I have always been a fan of solid roller cams. I dumped the TFS stage 2 cam into my build (great hydraulic SBF cam) because it was on my shelf. Hydraulic roller grinds simply cant follow the ramp angles I am looking for. The faster the ramps the more dwell time the cam designer has to develop the lobe profile. These are some seriously steep ramps I just ordered up. We shall see whats what before I advertise the grind. I am willing to bet the work involved that it will rock.

Glenn, are you planning on reving it past 6500 RPM? If not then the valves will only need adjusting about once a year. I always wanted to do a Dart 427W with AFR 225 heads, Ferrea valves, beehive springs with Ti retainers, shaft rockers and solid roller cam. Spin it to 8000 RPM and make 550 RWHP.

I'v been considering a solid roller for a while, but havn't made the jump yet. Only because I run out of gear about 2/3 down the straightaway. More rpm's and speed in that one spot might be nice. I think I would need to have a cam custom made, as I have not found exactly what I want out of any catalog.

Wayne, beehive springs? That's a little contraversial. I tried some on a hydraulic cam a few years back. But I must have picked the wrong ones, as I wasn't impressed. I have been reading about them for solid cams; I think from Isky. If I do decide to go solid, I would be taking a serious look at the beehive springs.

Exactly what I'm going for with small cubes. I am hoping that the shaft rockers (Crower makes nice ones) will help assuage the bereavement of frequent valve adjustments. I have good valves in the TFS heads, it should work. There is nothing like a mouse motor going 7500. Man I bet that would sound wicked through a set of stacks or webers.

I have used several Crower mechanical rollers in the past. The Crower rollers with the pin oiling are great, but one has to make some drain back mods to deal with all the top end oil they fire. They are really best suited to a dedicated dry sump set-up. I am using the severe duty, non pin oiling followers with intake offset. I will use the bee hive springs and split some pressure off with their "Rev Kit" The cam is not super radical. In fact it has a 112 LS figure. The acceleration figures of the lobe profile are fairly wild though. :) This should be a super responsive, power everywhere, no ceiling type of profile. i guess we are all going to find out.

Man I lust for an aluminum 427 one day. I agree with your want list. Nice piece that would be..

Go Crower and forget about them. A solid roller will do a lot more for you than RPM. A lot more. I really fail to see where I CAN'T PRETTY MUCH GET A SOLID, FLAT TAPPET CAM TO RUN WITH A HYDRAULIC ROLLER, UNTILL THE LIFT GETS WELL ABOVE .500" I did that in caps to hasten the flogging :0 Isky? Risky Isky my Dad used to call them. Some great stuff, some crazy stuff. Ed Iskanderian taught the politicians how to tell tall tales. Cam grinders in general are a tricky crowd where the first liar don't stand a chance!
