A 360 with 9:1 would likely work well with that cam. If your thinking 318, you'll need as much compression as reasonably possible. Say 9.6:1 and 3.55 axle in an A body.
Exactly. I wouldn't run that cam with OEM dished pistons. 212/212/.440 comp 260 is max on the low compression 360.
Its likely a good core. Howards hydraulic lifters, or your in Wa. Call Delta and get a set of lifters, he faces them.
It does by a long shot. They don't make that grind anymore. You used to be able to special order it but you caint even do that now.
Are you sure about that? Those profiles are still listed in their lobe catalog (#'s 5130/5135).
Almost 100%. They have "basically" the same grinds as the DEH but they renamed them something else and gave them a lot more lift and fast rates of lift. The durations and LSA are still the same.
I've got the recommended springs, also new, as well as a set of lifters. Someone bought the whole package for a 340 build I acquired back in '06.
Looks like they still have the DEH profiles. They'll grind it for you if you custom ordered it. Of course there's probably better options now.
Do you happen to know what are the .904 lobe profiles called?
Looks like they have a .904-specific hydraulic flat tappet lobe profiles in their "Thumpr," "Purple Plus," and "Xtreme Mopar" lines.
Interesting, that the MM SFT profiles list a maximum of .650 lift with 1.5 ratio rockers. I spoke with Jim at Racer Brown last month and he seemed to think .630 was about maximum lift capacity for the Chrysler cam core, but said he didn't like producing them...
Jim sent me an STX 20M for a build I did last spring. I complained about the low lift and he said, "look at the lobes."
FWIW: "let's say I've got a 360 short block with speed pro H116CP pistons @ .005 below deck."
i'd ask what the application was, what heads you had, what the rest of the combo was and why you would want that much lift.
