yea, i think the slant is the shortest of the I6s, it was used in little valiants and darts. to reword what rockin just said, he means some accesories are mount on the side the block, instead the front, like the water pump, making it shorter. theres a fellow on here with a falcon 200 in a ranger, he did no firewall/core mods. the only thing id worry about is the trans tunnel/cross member and heater box. now, im not dead set on a slant, if someone can convince me of one the other motors i picked out.
