Here is the stock cam specs and the Isky Rev Master cam spec's. Someone asked me for them and I cannot recall who. The Isky is a solid lifter version.

Still a relatively mild 260 degree cam unless you compare to the stock 244 degree cam which is just pathetic . LRDaum

---yes the cam is "mild" by 401 standards. This is for a 327. With solid lifters it can rev a little more and there is more lift. How many of these still exist? I have NOS.

What are the specs on the stock '57 Rebel 327/solid lifter motor? Compared to the 244 or the Isky noted above?

I have no records that show any other factory cam than stock from 58 to 68. I do not have the book on the 57 Rebel which may show something else. The mechanical and hydraulic lifter engines used the same spec's according to the 58 Service Manual. This is the same basic spec as the 6 cyl. engines and they shared the same valve size as the 290/304 engines.

The factory 290-390 cam is 266 DEG. & with the 1.5 rockers would have .398 valve lift , a smidge bigger than that Isky , however the Isky may have a faster opening.

"....1.5 rockers would have .398 valve lift..."
Did you mean lobe lift multiplied by 1.5? The Isky cam has .410 Valve Lift.

Yes , lobe lift multiplied by 1.5 . The Isky is .410 at the valve minus the .018 valve lash = .392 . What is the Isky at .050 ? , they didn't use those figures back in that time frame .

I was under the impression that the .018 valve lash was for heat expansion so I'm thinking that it would be closer to the .410 lift when the engine is hot. |
