mpg???
ok so i know this is does not matter because they are trucks and they are not made for good mpg, but i am wondering what people are getting with there trucks. the reason i ask is i have a 71 4x4 that had a sm465 with a 205 in it well i was dumb and pulled that out and put in a th400 with a 203 t case. now the thing just drinks gas like it is going out of style.
 i also put on a set of headers but i dont think it should have dropped that much! i know i could change the gearing but what would be good to swap to? thanks for any info i am really learning alot from this forum!!!
