    I remember it being something with POSTON tried to make both sides a mirror image with eachother... ended up making some cylinders lean. would a spacer alleviate this? Or trimming down the center divider? I have the opportunity to get one for cheap... was wondering what you guys would say.

    Thanks for any input.

    It ain't cheap enough. Lots of guys on here complain about the well made TA dual plane intake not being worth a swap(I'm not one). You can only imagine how mediocre an intake is when it was only built as a marketing gimmick. Anybody who runs the Poston and doesn't have actual performance data of a before and after trips to the drags or dyno test results don't know what the intake did for them and it likely is not good.

    Someone did dyno all three intakes. Maybe Sean has the info.
    But the s divider was more of an experiment. Then rushed to production to recover money invested. I believe jim Burek even said it wasn’t complete design. I guess your on your own to experiment. Or try contacting Jim . I heard pae is still in business.

    So, if I put the S divider on an engine, it will make it run worse? I can get it for under 150 bucks, if it does nothing else except save 50lbs off the front end, I'm fine with that. I have a 1/2" spacer as well.

    However if it is detrimental to the engine, then I'll salve myself the $150.

    used one for a making a s/c intake because nothing else has a big enough platform. other than that, a door stop.

    I would stay away from it, someone will sell their TA dp intake once they are happy with the SP3 which should be no problem.

    I got a idea, get the SP3 and get ready to build the motor up for some real power. I put this thing on and the car now practically starts itself up without much help from the gas pedal. Turn on the fuel pump give the carb 2 pumps from the big as double pumper and it starts right up and sits there and idle without stalling no choke needed.

    This is what the Poston catalog said about the S Divider. I have never heard anything good about it. I do know that you need to use a spacer to get the most from it.

    Only good thing about a poston intake is you can make it a single plane with enough work..

    Jim did re-pay all the money that he owed people like he said he would, right?

    Phil It really *is* a 350...

    I have an S-Divider sitting on the shelf in the garage. I have another 350 in the corner I was going to put it on. I bought it 2nd hand but I'm pretty sure I didn't pay that much for it. I can't speak for the performance yet.

    On the other hand, after running both a QJet and a couple of different Holleys, the original T/A Stage 1 350 intake I have on my car runs better with the Q-Jet on a 1" open aluminum spacer than it did without.

    all I know is an S-divider, read different views on it but when I bought my car the engine had one on it already.....but in the end....everything I read on it, it seems like the stock manifold would perform better.:(

    Of course not but it was not all his fault with the whole Bradshaw scam... I honestly do not think that Jim B was in on that scam but he was sure tied up and hung after it all went down... He collected a lot of money that was basically stolen from innocent people. Jim B did not profit over that fiasco it was the end of his Buick career.

    I am not saying he was perfect, there were a ton of issues with his business and his dealings especially during the Bradshaw/Bulldog fiasco were very poor. At one time he ran a good business but he will never again get the trust of 99% of us.
