1st drive with new 400sbc and powerglide trans

okay so for my 1st drive of the 400 things seem a little weird. I have a powerglide and tci 24-2600 stall converter. the car didn't seem like it wanted 2 shift out of 1st for a very long time. I only averaged about 30mph the whole trip home. but being used 2 the 307 I could tell when it needed to shift. the car did shift out of 1st when I let off and got back in a few times. could the motor b looking for a certain rpm before it shifts into 2nd? I have a big 488/510 cam with 114 lsa. should I b worried about burning up the trans or something? the torque converter is fairly new.
