    Default Probe forged pistons

    I have never heard of them, but they are part of a balanced rotating assembly from White Performance machine I am looking at. Anybody have any experience with them?

    Yes I have the Probe SRS 13729 in my 496 and it works real well with crower rods and scat forged crank. Crower actually recommended them as part of their balanced assembly.

    They are a low budget forged piston. They make 2 series pistons. The FRS series is more of a replacement forged piston much like a TRW made from 4032 aluminum. The other is a the SRS series forged from 2618 and are a little nicer. Some will compare the SRS series to SRPs. I personally would rather have the SRPs, and CP Bullet series over either of them.

    Carnivalride on the boards destroyed an engine using Probe pistons when the wrist pin seized in the bore from lack of forced oiling and possibly having a slightly tight piston pin bore.

    Not sure if they were FRS or SRS but my gut says they were FRS series pistons. No matter, you need to know what you are getting. I wouldn't recommend the FRS in a performance boat.
    There is some good info regarding what happened to Loren's engine in this thread if you bother to open his photobucket posts as well. Could save somebody else a big headache.

    Main reason Crower reccomends/sells the Probe is cost... they used to use/reccomend Ross a few years back for the same reason in their sportsman line of kits. On their higher end kits they use/reccomend JE.

    I'd say the Probe are on par if not slightly nicer than the TRW/SpeedPro stuff... but not as nice as the SRP and nowhere near as good as the JE and CP stuff. Again... cost... and in the parts world, higher quality carries a higher cost.

    i bought that same kit(h-beam rods, steel crank, forged pistons). the rods and crank are Precision Engine Parts, mine came with king bearings and motorworks rings. i upgraded to forged 14.1 probe pistons. they show a balancer and flywheel in the picture but it does not come with kit, beware of ordering from them and read the fine print.

    I SOLD MY KIT

    The OP didnt state what he is building his motor for, any budget amount, or any other specs; so its a wide open conversation (as always) as to building budget vs. reliability vs. longevity... etc etc etc....

    He asked if people "had experience" with them.... My 'experience' with the stuff is in a lake rod that was a budget build (about $3K) and runs on pump gas really well.... for the investment made.

    If hes got $10K to burn on a motor in a $50K drag racing boat then he can most likely upgrade everything on his build list. But... it doesnt appear that way

    X2. Not a big fan of Probe pistons, and there's not way I'd ever compare a Probe SRS to a JE SRP. You have to be recovering from some kind of serious illness to make that mistake.

    Oh there is no shortage of people that will compare the SRS to a SRP. The FRS, maybe with a TRW. But lots of people will compare the SRS to a SRP. I just don't happen to be one of them.

    Probes biggest niche seems to be filling requirements for Ford strokers, and making pistons off the shelf for things like Trick Flow twisted wedge double notched domes.
    Way too many other choices in the Chevy arena for me to choose them.

    No need to read the fine print. Better off just flat ass avoiding them altogether.

    Wow! To assume his CAST crank broke because of the probe pistons seems unreasonable. He may also have been eating french fries too-maybe that was it.But seriously, I am going to see if they will substitute JE pistons for the Probes for an additional cost,as I do value your opinion.-Thanks

    Really? Tell you what. Have the pin pull out the bottom a one of your pistons, have it fling around at 7000 rpm, have the pin(still in the rod) nail the main bulk head and see how long your cast crank lives.
    Its not unreasonable at all.

    Take your chances with an inferior piston and your whole engine is at risk.

    Point well taken-and I am buying a new eagle forged crank-not using cast.

    So what are you saying. That your crank will have a better chance of surviving if a piston fails?

    Did you miss the part where I said I would look into getting JE pistons instead of the probes?????
    You know, you don't have to be an ass EVERY chance you get. DAMN!
