So in a nutshell, the L76 intake made lots more power than the Carb intake. Did the carb intake have an intake elbow or was the TB on top?

I knew the L76 intake was much stronger but didn't want to post anything until I had hard data.

Those results are very similiar to mine when I did the Vic Jr to FAST 90 test. I used the Accufab TB on the Vic Jr and the FAST out ran it across the board by more than 20 whp and tq on my 347 with no other changes but the intake and both were optimally tuned.
Good info there and thanks for sharing.

No problem. My plans for this fall is to dyno again when it cools off then swap on ported 317's and the truck intake and dyno and then swap cams to something with a little tighter LSA but similar duration.

Dont doubt those results considings the huge ports on the L92 heads and GM intake and the smallish cubic inches your running. Now put same combo on a 427 cubed motor and i bet the out is a little different.
