Trying to finalize plan
Posted: October 1st, 2019, 3:36 pm
I have spent a lot of time over the last few weeks reading all I can find on stroking a 4.0L. There are a couple things I'm not too sure on. I have a 2004 TJ and the 4.0 is not going to do what I want with out modification. I have Syked tuning software that has helped some, but not enough. It does okay empty, but I want to pull a 1200-1500 lbs trailer. Where I live and parts of Tennessee I like to travel can have some pretty long climbs. I also plan a trip out west which I think will really test even a 4.6L. I really don't want the complexity of a power adder if I can help it.
It seems like there are not too many recent builds and most of the older builds seem to use 4.2 cranks. I'm a little confused on accessory drive using the short 4.2 crank and later 4.0 front dress. I am also not clear on the fitment on the Scat crank either. Which is the most cost effective route for crankshaft? Would a Scat crank have fewer things to trip you up?
Connecting rods seem straight forward. I plan on using my stock 4.0 rods, but do they really need any machine work if they come out and the bearings look good? Or is it padding the bill at the machine shop?
Is cutting the block the most cost effective way of zero decking or even out of the hole? How close can you run the pistons to the head?
