Very nice. I just pulled the 427 sb out of my '72 Vette last week. It was the last engine I put together with a flat tappet cam and it's time to update it a bit. Yours looks like it comes on early and hits hard.
She sure pulls everywhere I just had it rebuilt due to a very bad oil consumption issue. The rings were shot. The builder tried to blame me saying I ran it too rich. Even though I had it hooked up to an afr gauge. I believe the machine work was subpar. We'll see it's now back in the car.
