i have a 440 in a '65 coronet that is strictly a street car. i use a 238@.050"/.510 lift solid cam, 110lsa, with a 1966 street hemi converter; no mods to the converter, and a 3.23 gear. this drives very well, has a good ignition curve, but the converter is a little tight for the cam. i don't know if you can buy that .528 cam anymore but somebody ought to be able to grind something close. if you want something to drive nice without the loose converter headaches i'd look at something in the 230-235@.050" range and maybe a 112lsa. a bunch of valve overlap at idle and right off idle torque lose is what messes you up. my cam has about 75 degrees overlap and that's really too much for the converter. i don't want a looser converter because the 3.23 gear works good for in town and moderate road use. loose converters and tall gears are not a good mix.
