318 is a popular swap and has been done a few times. I'm not a big V8 guy but I think the 318 looks nice and compact in the small Ram engine bay. Like it fits and it wasn't shoehorned in with half the firewall cut away, wheel well cut out to fit headers, etc. Search around for build threads for ideas.

Do you have part numbers for the parts you need? I suggest digging through partsbase.org for your application and getting all of the OEM part numbers you need. Then head over to RockAuto.com and see what they have in stock.

People with way more experience than me said the power steering seal kit is a temporary fix at best and will start leaking again, because the physical gear gets worn down and new seals can't stop the leak. Thus to really get it leak free, the whole gear needs to be re-manufactured. That can run $250-300 on RockAuto.com but maybe you can find a local shop to reman it for less.

Please introduce yourself and truck in the Member's Introductions forum and post some pics up of that D50. Welcome!
