I think Melling actually makes a performance version for like a 340 replacement - Rock auto had them for something like 2.99 each?? I don't know, I can't remember off the top LOL
The problem I have with springs like that is, in one place you see one set of specs and another place you see different specs. The Comp 901 has the same specs across the board, no matter where they're advertised. The Melling springs may well be fine, but I've never taken a chance on them.
