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
