78mm, the 90 would be overkill. on a stock internaled car i'd just go with an ls6 intake and a S2/S3 TB.

The new 78mm FAST throttle body looks trick, but so does the price. I'm waiting for comparisons of the S2 and the FAST before I make my purchase. It would be bad *** to have a matched FAST intake/TB.

pdd, stock internals to us usually means stock LONG block.

Stock cubic inch H/C motor, the 90mm debate is still out. Been a couple that have gained, and a couple that have lost hp on the dyno with them.

I'm waiting till I see track numbers before making my decision.
