need info
what are the block strengths of the 351's
what are the rod strengths
and what are the piston strengths
searched for hours found plenty of block info but jack on rods and pistons.

lol i won't be worrying about the block, i'm not building anything that badass, just looking at using some turbo's on a stock rotating assembly no more than 575-600hp crank that is, and maybe more for track days. this will be a DIY JY project as there are plenty of cheap turbos from them that can feed CFM's needed to feed a stock shortblock 351w

your gonna need to change the pistons to a much lower compression number like 8 to 1 or 8.5 to 1 for the boost. While your doing that at least put in a set of I beam rods if not H beam rods or else you are going to make pieces. You may get away with a stock cast crank if you keep your rpms under 6500 or so.
Doing that sort of power on a stock bottom end is asking for it. my bud runs a 351w in his truck that he upped the compression and put new heads and all that on it but left the internals alone. Took it to a truck pull and he stretched every one of his rods and ruined the motor. Now that may be a bit heavier load then what your mustang is gonna see but at the track everyone always pushes their equipment a little harder.
Also from what I have read around here the safety limit on a stock block is about 600 horses.

what is the limit on the rods, but anyone that says the limit on the 351 block is 600rwhp is full of it...we have a guy here making 750 before the 200 progressive shot and he runs 5.90s @ 121 in the 1/8th the block is a 94 block

thats what im seeing is a bunch of guys just changing out to the trw pistons and then they're able to run 6-700rwhp.
any ideas on the best el cheapo forged pistons?

not to hijack this thread or anything....along the same lines as the OP....so if you rebuilt (new rings, honed, bearings, gaskets, etc.) a 351 with stock rotating assembly and fitting it with a good H/C/I combo with higher compression...could this be a good alternative to making power besides boost or stroking?

my goal is 350 to the wheel, and a 150shot on top when i put in a 351w
