i had my 73 blazer sitting for 6 months with a bad transmission. i didn't drive the truck before i bought it because the transmission case and flexplate were cracked. well i replaced the tranmission and flexplate, i take it for a spin and it has no power it tops out a 5 miles an hour. it has a new 350 in it, do you think the four wheel drive could be causing this. i tryed it in 4low and 4high and it went the same speed. i haven't adjusted my front hubs yet. but what could be up with it? any suggestions would be great.
