Cam design limitations
I think he's just saying "Never Mind". Anyway I think your best option in this case is increasing the rocker ratio if you haven't considered that already. Or go roller, those are the only 'safe' ways to get the rates-of-lift you need. Also I think turbo cams are traditionally dual-pattern with extra lift/duration on the intake side to pack the cylinders better. Heck if it was mine I'd consider just swapping up to 1.6 ratio rockers on the intake side (or even better 1.7/1.6 if they exist for /6), that gives you a dual lift pattern right there.
Thanks for the "N/M" explanation; I am not
cell-phone texting/shorthand savvy... if that's what that was...
Believe me, if 1.6 rockers were available for this engine at a reasonable price and with decent reliability, I would already have a set and wouldn't be wasting your time (as well as others') with this I am investigasting the process of modifying a set of stock ones , myself, but am just getting started on that investigation.
Roller blanks for a slant 6 cam are $1,000.00.... 'nuff sed. We don't need horsepower THAT bad; if we do, we'll just crank up the boost some more.
This is just a hobby/bracket project, will never be street driven, so getting the last tenth out of the engine is not a critical issue at all; just two old guys tryin' to have some fun. That doesn't mean that we're blissfully unaware of certain technical posssibilities available, but we're not knee-jerk about it, like if it were an NHRA class car.
Thanks for your insight and information. It was duly noted, and appreciated.
