    by the way i read that too about them failing, but i also read the problem was corrected, do you think that -with the failing issue aside- they're good springs to run because the dual springs are $100 more

    $100 more, but they come with new seals, retainers, guides, everything.

    do they fit in where the stock sized spring was? is it harder on the other parts and motor in general to run these stronger springs?

    Not really.
    Spring rate is a little heavier, but not much.

    And yes, those fit stock heads.

    Retainers have to be installed either way. Old or new.

    yeah the guy at texas speed also pointed out to me that the springs last longer than the comp 918's as well, which convinced me to do it.

    so what all did you end up ordering??
    i was thinking of just getting the LS6 springs.
    Also, how do you decide what length to go to on the rods? i have heard that when you go more agressive on the lift, the length needs change too. but which direction?

    i know the 112 vs. 114 LSA TSP 228R cam may give a little more low end power, but are there any drivability issues verse performance gains? but, does it REALLY matter between the two?

    i really like the sound clips i have heard of this cam! and it seams to have impressive gains.

    yeah as far as driveabiltiy issues i've ridden in a 112ish car and it really wasn't that bad, granted i'm a 20 year old kid and i couldn't care less if the car has a/c... cuz it broke a while back lol... from what it seems like though, this is a pretty streetable cam regardless of lsa, from what i've read,
    but no, i don't think it's THAT much of a difference at all but i'm no expert

    LS6 springs are only good to .550" lift.
    Honestly, probably a wasted swap.

    The things that change the pushrod length...
    Lifter preload.
    Heads milled.
    Base circle of the new cam.
    Block got decked.
    Rocker pedestal height.
    There are several other things as well, but those are the more common.

    One should always use a checker to be sure anyways though.

    how did stock length work out for you? did you change springs too?

    You HAVE to change the valvesprings if you install ANY cam (aside from a new stocker).
    The stock valvesprings barely handle the stock cam.


    Verify pushrod length with a length checker.
    Most aftermarket cams are a touch smaller on the base circle. Which means a touch longer on the pushrod would be a good thing.
    Stock 7.400" pushrods may make a touch of noise with same cams, as they are a hair too short.
    7.412" would be about perfect....but those are a custom made pushrod.

    worked fine. i used patriot double gold springs (to .650 lift) with their own seats, seals, locks, and retainers.

    made 385/370 at the dyno last weekend. the clutch is slipping like a sonovabitch too, so while torque was measured, rpm was over 1000 off screwing with the hp calculation. so actually there is more torque to be had, and a good bit more power after a clutch swap.

    this was on a loaded land&sea dyno, similar to a mustang dyno. the cam is a tsp tqV.2 232/234 595/598 113lsa+1
