no power

[cool73chevy]

hey guys , i have a 73 blazer with a new 350 and i just replaced the transmission and flexplate because they were cracked when i bought it so i couldn't drive it. well after i finished the job i took it for a spin and there was no power i mean you floor it and max speed was 10 miles an hour. i put it in 4low and 4high and it went the same speed.i am thinking maybe my front hubs are between adjustment, what do you think is causing it?

Did you keep the old torque converter?

no it was a new transmission so i used a new torque converter. i was thinking maybe i didn't seat it enough but it think it did.

Did you properly fill the torque converter before re-intalling?
