I have that cam in my 400. It has #48 heads, with somewhat more compression than yours though. Nearly smooth idle and good vacuum for power stuff.

Or Summit's K2801 would also be a good choice...Robert

Look at a Comp XE262, works good w/low compression, good idle, no flat spots in power up to 4800rpm, works good in my 79 TA 400 4spd, 3.23.
