Brainstormin' 440 vs 5.9 ...

Well, I'm really leaning at this point to run it as the RV 440 smog motor that it is before "building it". We'll see. Give me your honest ET guess if I do this .... Because I have no idea what a smogger RV 440 will run in a D150
how smogger we talkin' here? stock TQ with all the goo-gaw **** on it? smog pump? lean burn?

any gear or stall?
