Hi guys,
I have an LS1 in a 67 Nova with extremely tight clearance in the front for the intake setup. I am debating switching to a FAST 92 or 102 but I need to know if it will move the TB any further forward or backward compared to a ls6 intake. Does anyone know?

Bonus points if you know if aftermarket TBs are any deeper/shallower dimensionally than the stock LS1 TB.

thanks

I went from an SLP LS6 intake/stock ported TB on my LS6 swapped '98 Z28 to a FAST '92/Nick Williams 92mm TB and I can't tell any difference on where the TB is located because I'm still using the stock accordion bellow too. Seems to be the same as far as I can tell. The runners are obviously molded differently and my LS6 FRC's don't fit quite as well, but it really is physically VERY close from what I observed when I installed mine.

My LS6 is all stock internals and I picked up 15 RWHP going from LS6 to FAST 92. I'm sure it would be more if I did heads/cam!

I actually had to modify my lid a tiny bit to fit the 92 TB and intake. The way it angled into the lid was not exactly the same as the LS6 setup

Thanks guys. Any other input? Do the FAST manifolds angle the TB up at a slight angle similar to the LS2 intake or is is straight out like an LS6?

Mine was angled up compared to the LS6...which is why I have cut and modify my lid a little to make it all fit.
