5.2 to 4.7 ?? - 4/25/2008 10:33:48 AM    v8streetracin   Posts: 32 Joined: 11/23/2007 Status: offline hi i have seen posts about going from a 4.7 to a 5.2 or 5.9.  but was wondering about going from a 5.2 to a 4.7???   i have a 99 5.2l that blew up a month and a half after i bought it. dieing at 108,000 miles i was really pissed. warrenty didnt cover shit on it due to a gasket being the cause.  anyway after i heard last night that gas is going up to $4.40 in the summer by my area.  already needing a replacment i got a quote for $3200 for new 5.2l engine 3 yr unlimited mile. i started thinking if its possible to go to a 4.7l .   like motor mounts same place? will trans bolt up? will computer read the same ??  diff wiring? radiator should be fine due to smaller block but not sure??  and the MAIN question i had for this brain fart. would the .5 L give me a major differance in gas millage??    this is my daily driver.  put it this way in the first month 1/2 i put on 5,500 miles so you can say i drive alot.  gas is a major factor for me.  but i also want that power i need for wheeling on the weekend.  or i should just give in and get a bike for when im not working.    any info will help thanks Post #: 1

If you want better gas mileage, you should consider fixing your truck the easiest way (another 5.2) for your weekend wheeling and pick up a beater Civic/Corolla type car for the daily driving.   Check sites like craigslist.  You can ususally find a few cars for cheap locally.  (in reply to v8streetracin) Post #: 2

This will cost a lot of $ probably about $6000. Not worth it! Just replace the motor with a 5.2L. _____________________________ 1998 Durango, 5.9L Built Motor Bored 20 Over, P&P Heads, K&N Ram Air CAI, MSD Ignition, 52MM Fastman TB, Built T-Case, Custom Built Trans, Air Bags, Magna Flow 3" Cat Back Exhaust On and On!
