    do you mean Racetec, i have the Racetec pistons in my 340 there a good piston less money than other brand names,the total seal rings they sent were not very good ended up with a different brand. the guy that use to own je pistons started Racetec.

    Joe, whats a set of forged pistons for your 340 cost from this company? Are they the light weight ones? How do you like them?

    they cost 530.00 plus 80.00 for the pins. there a nice street piston where you can run a 3 thousands wall clearance. lighter than stock mostly because of the lighter wrist pins. i would buy them again. they must be the same ones Sean talking about.

    Why don't you just use Gran National pistons. There's probably 10 companies making Forged pistons for GN. Same bore, same pin, no?

    I believe theirs a difference in pin height/compression height piston could end up too far down the hole
    ..that and you have to buy 2 sets as i dont think you can buy 2 individual pistons ontop of the 6pack.

    This works sort of, just ends up at about 7:1 unless you mill the crap out of the block and heads...

    The turbo v6 pistons have a higher compression height but low ratio since they are made for 48 cc chambers.racetec has 2 piston s for 350. Basicly a street piston for about 9.5 comp then a race for 10 plus ratios. Still a reasonalbly priced piston.summit racing does sell wiesco v6 pistons as singles.they also have 2 compression height choices.just have a huge dish.good for turbo engines.racetec uses Je pistons for v6 . This info is on the site just got to search around.

    What about those flat top v6 pistons? Lower CH but no dish...

    You can get them individually too so it's not just a 'set in stone buy 6 or forget about it' deal.

    There's options, and the 3.8 v6 makes the 350's piston options even more.

    Yes the 3.0 GM pistons are great for high compression engines and can even be used for boosted applications if boost is kept under 10 PSI.

    The bad thing about running a flat top in a sbb 350 is that they don't compliment the chamber design of the sbb 350 head like a dish piston does.

    With a zero deck,or very close to a zero deck,I don't think it would matter with a FT(and compression would be very high),but a flat top .040"-080" whatever it is in the hole wouldn't let the flame travel as good as a dished piston would,even if it was in the hole as far as the flat top.

    That is why these pistons that you posted are a great alternative for someone building a sbb,especially the option to customize them at no extra cost.(you just have to wait about 3 weeks longer for them)

    I agree, the flat tops are great for budget builds more than max effort deals. But when going high performance it is money well spent to use lighter stronger pistons. The stockers or the flat tops are HEAVY slugs and I am a firm believer that is what kills the rods at about 500 HP. With light pistons I bet the stock rods would last well into the 650 HP range... However it is a slippery slope, go with good pistons, might as well go with good rods, might as well add some stroke... Might as well dig a pit and bury your money LOL...

    Getting info from them now about custom piston with .827 pin size. They already have pins. We will see what specs the piston will be. Hoping for about 8.7 compression for boost use.anyone in Illinois know a great head porter or maybe see what Bob does for Buick heads.

    All said and done, I'd probably shoot for deep dish hypers and some deck milling along with plenty of polishing on pistons and heads for a smooth combustion chamber.


    Also something to consider are the valve reliefs, quench platform designs, etc. creating sharp edges and hot spots (even smoothed out (which helps) they introduce warmer areas and uneven weight), in addition to offsetting the weight distribution of the piston, especially when all these things aren't needed (aside from valve reliefs in higher-end apps) in the small, open combustion chambered design of the Buick 350. As Derek pointed out, dish is best for flame travel.

    I don't think they make custom hypers with smaller pins and are hypers really going to be lighter then forged?also why mill a block/heads to get compression up because pistons are not made to "advertised" so far I haven't been impressed with any off the shelf parts for Buick engines. This is why Buicks are so expensive is you have to fix what parts you buy so they work. Sorry for the rant but I'm sure you know what I mean .

    Oh I was just speaking in general for pistons.

    Not sure what the weight difference is on hypers vs forged, though the hypers I have in mind have the 'low compression' deep dish so that means less weight, with the weight closer to the rod, which brings me to something else I forgot to mention: bringing the piston closer to the rod (less CH) helps to centralize the weight better rather than making a custom piston that sits up higher (and therefore further away).

    Seems if you're going to mill the block anyway, might as well have it zero'ed to match the deeper dished, lighter pistons.

    I may be wrong though, but this seems logical to me.

    Not sure if hypers would be the answer to your build with forced induction. N/A is more what I was referring to. Forged might be your best bet, though you can get deep dished forged too.

    Something like this: http://www.summitracing.com/parts/sl...iew/make/buick

    Speed Pro's pistons (according to the pic) have more of a rounded edge on the step instead of the steeper slope on other forged pistons I saw there.

    Rounded = better design

    Don't forget zeroing block takes away valve clearance and requires new pushrod length in most cases which adds to the expense of the wrong parts.just my theory.

    Putting higher CH pistons in there will bring them closer to zero deck so it doesn't matter either way for valve clearance concerns. Push rods aren't very expensive, considering the cost of the rest of it, plus you're shaving off even more weight from the engine and making it more centralized by lowering the CH and milling the block. I know it's not by much but small numbers make big differences with engines.

    These are just some things to consider.

    These aren't the wrong parts. You can spend more money on custom pistons if you want plug n play, but off the shelf stuff is made to fit a generalized spectrum of applications, and 'some assembly is required' meaning you have to do some cutting and fitting here and there, but the heads and block have to be machined anyway to true them up.

    If you want to get technical, anything other than the OEM parts are 'the wrong parts' which includes cast piston sitting deep in the hole, the French tickler bump stick they call the OEM stock cam, complete with casting burs left in place on head runners, mushy valve springs, etc. etc.

    You just have to find where you're willing to draw the line when it comes to building it. If you're wanting to stroke it out, that's a ****ton of extra money right there that could be better spent elsewhere, IMO for your money. Leaving the rotating assembly stock with capscrew rods shotpeened and cleaned up with light pistons will serve you quite well.

    I'm not trying to disagree with you, there's just so many ways of going about it. You can take my suggestions for what they are. Just tryin to be helpful.
