Re: swapped inline 6 for 351 windsor
What year truck? The motor mounts for the 6 will not fit the 8, you will need to get different ones. I'm not 100% sure, but I think you might need a different bell housing as well. The last time I did a swap like that, it was with a Dodge and there were bolt holes for the different configurations, I just had to figure out where to put it all.
Prius repellant, just add gas.
