I bet with heads, exhaust, cams, you would be happy. Maybe even a tune to go with those 3 mods.

I would stick with the 4.7 also. I have found some sites that have mods for the 4.7 you just have to google them a little. If you are going to do the 5.7 swap you will need to make sure you get the AEM computer modual because if you get a computer from a truck that was wrecked along with the 5.7 IT WONT WORK!!!!! There is a lot of programming involved with the new computers that basicly make them vehical specific. I have seen lots of guys with 4.7's in there truck with just as much HP as HEMI rams and you will be spending a lot less money to mod up your old motor than to do the 5.7 and tranny swap. Just my 2 cents.

As much as I love the old 318, the 4.7 is actually a better engine, more power with better mileage.

My financial advisor "The Wife" , has officially pulled plug on the engine swap, after reading all posts. But is budgeting $1000 for performance mods. Not bad considering my last budget I spent her "bonus" chk from wrk + my own for mods to my trk and "her car"!!!

I currently havea Volant CAI, thats it Now for the suggestions ....

Thanks for all input Matt
