I've been wondering that myself. Since no one looks down their noses at a sbc 350 or even a olds 350. Both of those seem to be routinely built with 220 or more duration @.050 on the intake side without a second thought. But the general consensus seems to be that much duration is too much on a Poncho 350.
Agreed. In my 9 to 1 214/214 .472/.472 110 LSA cam idled at 800 rpm decently smooth had 16" of vacuum and worked great with a 2350 stall and 2.78 gears with a 25" tall tire. With the 1600 stall, pretty doggy off the line.
