Cam spec question:
*Comp Cams Solid Cam, 244/252 @ .050", 110/105, .600/.610"
I know Brent is not a fan of flat tappets, but solid rollers would not fit my picture of a reliable street engine. This a solid roller or solid flat tappet?

Not a fan, but after an hour or so of discussion, Mat and I came to that agreement. Road racing can bring out the revs sometimes and I just didn't feel comfortable with the engine stretching its legs on a hydraulic roller. Conversely, Mat didn't feel comfortable with the longer term maintenance of a solid roller, so we hit in the middle.
This particular cam is a nitrided core, plus I'm using newer EDM lifters. With the inner springs out, the seat pressure is 93 lbs and the open pressure is less than 300. So with the cam core, the lifters, the springs, and a case of Brad Penn break-in
oil, I'll break this puppy in. I've already checked that the lifters spin in the bores and I can always get them to fire on the first crank on the dyno. I think we're in good shape.
FUNFER2, there is also an external pump wet sump system....
