Slant 6 225 swap
it can be done, you will need new motor mounts (schumacher),V8 radiator, you will want at least an 8.25 rearend as a 7.25 might not hold up too long, hopefully you get the transmission along with your 318 to make things go smoother as well.might need a driveshaft. i have never done this swap so i imagine there will be other parts needed than what i had mentioned already. personally i am a huge fan of the slant 6. they can be beefed up as well if you find that an engine swap will be too much for you right now.
