How much can stock rails flow?

[Dagz]

I am just putting my motor together and have a question. I need to know when my stock fuel rails need to be relaced with aftermaket high volume ones. Here is what I have. A fox short block with forged stock pistons. the block has never been decked, .40 head gaskets, edelbrock performer aluminum heads 170cc, edelbrock performer upper and lower/intake and elbow, 75mm throttle body, stock rails with 42lbers, and a matching maf, with 1.7 rr's, long tubes, off road x pipe and cat back, adjustable reg. vortech v1 s trim with a 3.33 pulley and an anderson power pipe. might be forgetting some things here but if you need more ask.

Thanks again for the help

You'll be fine, I've taken them well past 500rwhp on many cars.

i'm still running stock rails on my combo. you'll tap out the injectors before you peg the fuel rails.
