This is a for a 63 Skylark... High compression 215, 4 barrel. Will eventually add long tube headers. Mid-high 3 series rear gear. Short tires on this car (24") so a lot of effective gear. Overdrive trans with 3.06 first gear and lockup. I'm ok with up to a 3000 stall converter. I would like something with a noticeable idle to it, but that cleans up fairly quick. I'm thinking the most I would want to use is a TA212 ground on 110 center. Also considering the Crower 50231. I don't want to completely blow the torque curve, but something that pulls strongly from 2000 or so and extends the powerband on top would be nice. What do you think? There is so little information about this motor compared to the 350 and 455.
