This does not strike me as what goes into a 'good cruiser'. It is getting into street/strip... IMHO. TC stall will have to be pushing 3000 RPM...revs can go to about 7k.... A 3k-7k RPM range is a smaller RPM ratio than a 2k-6k engine..... A wide operating range with a wider torque band makes a car easier to drive for general street use. (I raced a 4k to 8k 4 banger engine for quite a while, so I do kinda know that end of the spectrum.) Not trying to be disrespectful at all; the solid just does not seem to me to fit the desired application.
As for the solid AMC lifter to oil... look at the Comp Cams 801-16. That looks to be what would do that. There may be other brands.
The DCR first then SCR makes a lot of sense.... I actually start with an SCR and cam, get the DCR, and then adjust the cam or SCR a bit if needed to maintain the desired DCR limit. It just is that for a typical hydraulic flat tappet street cruiser cam, like the 268ish type, the SCR ends up at around 9.5 for pump gas and iron heads, for the pump gas DCR limit of the low 8 range. The 268ish hydraulic flat tappet gets set by the RPM range and stall.... like discussed above. It may be boring to do the same thing.... but there is clear rationale behind it.
