4.7L question..
 
So, I don't need my jeep for a dd anymore and I want to make it more fun.

Should I just install the HO cams, on top of all I have done already. Or go crazy and pull the whole thing our ind add new heads (maybe pistons) and all new internals. Or should I do a custom rear mount twinturbo setup?

And can the HO cams be done with the engine in jeep? Room looks wayyy tight even after all the pullys are gone.

do it right bro. I would go through it top to bottom...especially if your gonna go F/I. There are tons of forged parts now for the 4.7 and honestly....youll need more than the HO cams.

If you decide to do the HO cams and springs....its not as bad as you think. You dont have to pull the motor...just the intake mani and the accessories on top of the valve covers. Pull the covers and the cams are right there.

I may just do cams, springs, and new gen intake manifold.

I just can't decide!! And the TT setup wouldn't be good offroad.

By tune, do you mean superchips, or one custom made by a shop? Reason I'm asking is cuz I've been getting quite a few side jobs fixing people's ac, and I'm starting to burn a hole in my pocket.

So what all is needed to do a cam swap? You have to do anything to the valves and valve springs?

Scottina06 07-29-2010 02:08 PM

Re: 4.7L question..
 
just the springs
