with the 6K RPM ceiling imposed by the owner, is there much advantage to a solid cam over a fast rate hydraulic? in some of andyF's articles on his old 470, IIRC, a comp juice cam kept up with a solid pretty good until ~6000 RPM, and that's where the juice cam peaked, while the solid kept going up.
especially if it is destined for a street car, could a hydraulic roller cam have made the same amount of power with less questions of durability given the state of modern oils?
just a thought....

After the first cam went flat, the customer and I talked about seveal different ways to go...however he already had the Schubeck lifters and after close inspection with a mag.glass we decided to go back to a FT cam.
I could have gotten Comp to build a set of hyd. roller lifters for the 48° block, but after discussing it with Billy Godbold and Chris plus my own experience I felt that with the 1.65 ratio rockers that the best way to go was the FT cam.
Now I might have been wrong about that, but I've seen hyd rollers give up some steam near 6000rpm, and I didn't want to go through that...mostly because the customer had already spent so much and time was wearing down on this project.
We did discuss going solid roller, with my lifters I felt it would last quite a while, but in the end cost was a bit high and I think the customer was tired of the hassle and $$$ spent.
If he hadn't had the Schubeck's I think we would have went with a streetable roller grind which is what I really wanted to do. I wanted 650HP from the start of this project, but limited my dreams to 620's with the FT cam.
I think we would have been there with the first cam.
I will have pics up this weekend I hope, maybe sooner. Not anything much different than what I've posted before, but at least they are fun to look at...LOL!!

Close!
I've often wondered, the indy heads don't clear pushrods on a 59 degree solid roller or a 59 degree hydraulic roller and apparently they are really tight on a 48 degree flat tappet too?? What exactly do they have those pushrod areas clearanced for???
