4.0 build
 

well my engine may have a few problems, ill be running a few more tests on it early in the week but for now i want to know about building the 4.0.

is it worth it? i wouldn't be doing too much, cam, valves,springs, just top end work.

prob not worth just doing top end work on a 4l.
i have been thinkin bout building mine up when i pull it for the timing chains. if i do i might bore it out, put a cam in it and some other things.

yea i didnt know if anyone had done this and got any hp specs on it or anything, but seeing how i may have it all apart i wanted to see how much hp i could get with just the top end work

I opted out of changing them damn chains..... for LESS money, I got a 1,000 mile 4.0L from a 2006. Complete with everything intake to pan, complete wiring harness, all accessories minus a/c compressor and alternator.

well you my friend have a later year then some of us

Some of the links to the pix are down right now but a good read if you have the time and really wanna know what to expect.
