well, i don´t know is the 434 is a better option than 400... have forged crank.
i know 400 rebuit kit is cheaper than 434.

I want to rebuild my engine as street.

I didn´t see in FSB broncos using 434.

I plan on doing a 434 next round. the reason the 400 kit is cheaper is your not getting a stroker.

For the street a 400 is probably good enough. Just be sure to get your parts from TMeyer. Once your block is all cleaned up you will know the overbore & you can order pistons, rings & bearings. Do you want to run the closed chamber heads?

pffffft what kind of answer is "good enough" when the question of high performance is on the line here?!?! he doesn't want good enough, or he'd leave it a 351m. he wants OVERKILL.

besides, it's a heavy ass bronco, so it's going to be slow no matter what he does, he needs all the engine he can get if he wants it to be faster.

as for the 400 vs. 434, consider rod length, cam choice, and TDC dwell a little as well when you're doing a stroker build. if you're going with stock heads, and the stroker kit uses stock rods, it probably has a horrible rod ratio like <1.5, and very little TDC dwell time which will result in not much breathing due to restrictive stock heads. so it wont make much high rpm power. just somethin' to keep in mind.

I am fairly sure Tim's 434 stroker kit comes with new rods.

Sweet.. those are some nice long rods.. and with everything being forged, i'd go with the stroker for sure!
