Beta Hunter's Engine pack 2.5

Title says it all, bastion v8 in the truck, both 5.7 and 6.5, up next is the v6 and a bolide swap

for both pessima's I removed them in this update as the swaps need work still, so for those who use the vortec in the pessima please bear with me here

For any suggestions please pm me
for critism pm me or leave a review on why you gave the rating you did, it helps me alot to improve this
