All terrible ideas except the 03 replacement engine. That first link is for an eagle crate 5.7. ATK doesn't exactly have a stellar reputation on their builds.

Custom or no more than comp 260 cam unless you're willing to change your harness and PCM over, because NOTHING that has been suggested nor dropping a 6.1 in will work if you can't tune it properly and you can't tune it properly with that **** 03 PCM.

Just posted that stuff and put out there for an idea. Last time I did engines, was from a 67 396 to a 70 327, many moons ago...Things were just simpler back then...

Yes they were...so you downgraded, or is that the range of engines you worked on?

Yup you used to be able to take a engine from A an stick it in B an ride out, deff not the same game now a days. The stuff you posted for us 3g guys is bout useless

Op what’s your goal, an what’s your pocketbook an ability of turning a wrench? These mopars seem to really jump up in price rather quick when we start doing performance mods

 

[turkeybird56]

Downgraded because could not find any L4 396,s. so dropped down, bored out changed heads and dropped in till we blew it up. Put 8 gallons of oil in yet and drove to Junk yard, those were the days...

My days of playing are done. Not have the knowledge to do these computerized electrical gremlin critters, with all the crazy electronic, minimal tolerances, etc.,. Guess cause I a lil old and from diff generation. Just do basic stuff, and leave it at that, que sera sera.

Yup, the whole mechanics side of modern vehicles deff heavily rely on computers. Some of it good some of it bad but that’s just the whole moving with times unfortunately.

Alright my opinion, I would do a a forged piston/ rod combo with a 6.1 crank. A nice lil cam an turbo it. Lots stroke to 392 I kinda would like to keep it close to stock displacement. then figure out another trans option since the 545 is ****. So figure a good 10k for my maybe 7k truck lol
