What are you driving?

 

an 03 ram 1500

 

Ok, moving this to third gen ram section. There are several threads on just this topic, may wanna try a search.

 

If this is your first ever engine swap then this is not the swap you wanna cut your teeth on lol.

 

Some info here. Plenty more with google search

Personally I would not even attempt this without a complete donor truck fully accessible to me. That way you have everything you need ! and you can remove the parts yourself so not to cannibalize anything fyi 03 and 04 Hemi's are known to have have weak valve springs.
I wish you luck. This something I would of done years ago when I was younger.

 

Way too complicated if you ask me...

 

Some are. You only ever hear about the few that did, the majority did not, like the 160k+ original valvesprings I have on a 2003 lol.
