2000 TJ 4.0 Stroker

I know a bunch of people has built strokers for their Jeeps. I was just wondering the do's and don'ts of this build. I am wanting to do the 4.5L stroker.

4.2l crank
4.2l rods
4.0l stadard bore pistons
comp cam #68-231-4
DYI ported cylinder head
stock .051" head gasket
.081" quench
24lb ford injectors

If my block needs bored I will probably go up to 4.6 or 4.7. Any pros or cons. Any info for the build that might help. Anything else that will need to be done during this build?

just go 0.060 over (4.7L) and don't look back. you can do 0.060 over and still have enough sidewall leftover for a supercharger, you don't even need to get the block sonic tested.

make sure you use LOTS and LOTS of cam lube when putting the cam together.
