This one is a nice one, it did everything well. The TFS worked great on the big bore. Built for a C-6 street combo with power brakes and a shaker.
Here's one of the dyno runs, came on like gangbusters mid-range, video almost doesn't do it justice

Out of all the TFS builds, I think this produces the most torque I have seen. Most of them seem to be in the 600-630 range.

It sure liked the BT intake and super sucker!

Ya know I like how a lot of your motors are making substantial horsepower and on this one especially gobs of torque with a fairly mild camshaft.

Awesome build , excellent power and torque down low

I think Ross has a thing for 489s.

They tend to find their way to me :) However, the next four will be 347 SBF, then 496, 505, and 511 FEs, A couple of 390s may sneak in there too.
I'll post later on the dyno partner that we ran just before this one, very different purpose and unique combo but too cool for school too.
