[WARBIRD89]

Hi Steve,

I hope you mean a 109 block and not a 409 block, big (pun intended) difference. Yes you can use a 109 block, the difference in the 2 blocks (109 and TTA) is, the TTA block is an after market block. The TTA block will have SG1 embossed on it at the bottom rear by the motor mount. If you want to keep your TTA as built by PAS you need to find an SG1 block. In saying that, the 109 is on both blocks. Some say that the SG1 block is stonger but, I have seen no proof of this. I believe Pontiac bought the 109 casting from Buick, so the are identical with the exception of the SG1 designation.

Please define the term "AFTERMARKET BLOCK" --- Turbota.

I think the # on the 2004 trans is 409, the engine block is 6109.

Sure, produced after OEM is discontinued.
