need some things sorted out before i start...

ok so i got a 93 zj bout 2 years ago, and i decided last year to finally fix the oil leak, then it turned into a rear main seal job, which ended up with us checking the thrust bearing and finding out that we had 0.075" of movement in the crank. so we pulled the motor and sent it out to get rebuilt. at the time i didnt know bout stroker kits and home built strokers . so anyway, it needed a new crank and got a used 4.0L crank, bored 0.030" over, Comp Cam for fuel injection, and complete head and valve job. now that i know more about strokers, i want to build that motor up with 4.2L crank and rods, with roller rockers, double roller timing set, new pushrods, and new fuel injectors. i was wondering what companies/ products are the best to use for a 4.7 setup. if i could get websites for the roller rockers, injectors, double roller timing set and pushrods that would be awesome.

You may want to start off by using the search and checking out some of the builds in the project section. That will give you a lot of the information you are looking for and give you plenty of things to choose from.

ok thanks, and i just thought of this question, i got new main bearings to go with that new crank, if i put a 4.2 crank in would i have to get all new bearings even though it hasnt ever been run?

also would a double roller timing set for a 4.2 work with the 4.0?

If the bearings are the correct size for the new crank you shouldn't have any problems, the timing set needs to fit the cam so if your using so it will work with the other crank.
