I did not do a before/after, as I built the engine from scratch and did not have another manifold. It's a 402, made 538 at the tire. Only reason I'm selling it is it's a swap application and the FAST is too tall. I hate to think about what I'll lose going to a ported LS3, but it's better than making a hood. $620 shipped in its original box. I will probably end up keeping the tb, as it should work on the stock LS3 intake. The intake is pristine. It is not ported, but, per recommendation of Ed Curtis, my cyl head guy trimmed and matched the trumpets an inch or so ( they were fairly close to the floor of the manifold) and it did pick up another 200 rpm of power and showed an additional hp of gain.
There is a guy local to me with a 402 LS2 than says his made 11 hp and 8 tq peak over his radically ported L76. But there are so many variables in before/after. The design on the FAST alone is enough for me..it's nice.
