First time engine build and stoaked!

No, they are too large. Cold start will be loopey and WOT will be off the wideband rich.

I'm still looking into injectors as thats really the only thing I can't seem to figure out. From what I understand, my 99' TJ uses a 66% duty cycle. So a 240 hp stroker will require about a 27lb injector at 49 psi (25lb at 43.5 psi). I'm being told on JF that 0280156048 from bosch would be the ticket. Any thoughts?

I've found that when it comes to the Jeep I6, if you divide the expected crank HP by 10, that's about the fuel flow you'll need. So a 240hp stroker will require injectors that flow close to 24lb/hr.

On the pistons, FalconGlobal is respected here for price, your choice of size, with the rings and no sales tax, seems sound. RockAuto shows 36.99 each without the rings. Note the return policy of seven days, that's tight to know you ordered the right size if the block is not ready and waiting....

that may be true but if you atleast have the head off and can see no deep scratches than order what ever size you want and have the machine shop bore the block to fit the pistons.
