    Im eventually going to purchase one of his pans.

    Isn't TA producing one soon too?

    TA Performance has been working on one for a while, as I understand it.
    When I talked to Tim earlier this week though, there is nothing available now or in the near future. I got the sense that it’s more of a long term project that is a little back-burnered right now

    Steve doesn’t charge too much to modify the stock pans. Well worth it... his alum pans are art work!! I’ve got the only one he has made so far.

    Damn. I must have my settings wrong again. Let me see if I can fix it.

    Refresh our memories, are you going to run the new TA aluminum 350 heads?

    If so, why did you buy full dish pistons with NO quench pad? You should of got inverted dome for the TA heads, they can say those are inverted dome because the factory heads are open chambers.:rolleyes:

    Chose these pistons to hit the 10.5 compression ratio target for this build. Without the dish, the pistons would have to be too far in the hole to give any quench.
    Zero decked flat tops would push compression ratio way above target.

    They could of made them with the same CCs and still have a quench pad so you could of got the very same compression ratio with the in the hole the same distance as the full dish pistons you have now.

    To take advantage of the TA heads closed chamber design, pistons with a quench pad are needed. An engine with closed chambers heads and full dish pistons is same as having open chambers heads with pistons with a quench pad, will be no quench.

    3.8 chrysler.jpg For the T/A heads this style of dish would be good for more quench at zero deck:

    Are those for a small block Buick?
    I purchased the best pistons I could find for a Buick 350, there are not that many to choose from.
    Maybe I missed some options?

    Darron, No. 3.8 Chrysler V6. For the smaller chamber on the T/A heads I think the deeper oval dish with more quench area would work good in a custom piston like you have done.

    Those look like my pistons except mine have slightly less dish. IMG_2372.JPG IMG_2397.JPG IMG_2396.JPG

    The issue with pistons for a Chrysler 3.8 V6 is that the compression height is WAY off, by a half inch or so. Don't see how that can work well.

    AutoTec pistons are good, you just need to order them right.

    Another board member bought a set of A/T pistons and they tried the same crap with him by sending full dish pistons when he wanted inverted dome pistons!:mad:

    He called and they sent him a new set that were the same specs but were NOT full dish pistons and he got to keep the dished pistons too. They probably let him keep the first set because of the custom wrist pin size so they may want your set back if you tell them you ordered inverted dome pistons with the same specs. If your pistons have a common wristpin size and a common compression distance they'll want to try to trick someone else by selling them those.

    They'll try to tell you that with open chambers that a full dish piston IS an inverted dome, this is where you tell them that the new TA aluminum heads have a quench pad so you tell them they are wrong!

    If you're running iron heads then you don't need to worry about it.

    Darron, You misunderstand. That dish style for a custom piston.
