Unfortunately for my wallet, my LS7 manifold was already on the way from England when I found this out, so the whole LS3 416 kinda went out the window in favor of something big enough to fit the manifold. The engine block went off to Steve Demerjian of Race Engine Development. It is going to get the dry sleeve treatment this time around. I'm going to throw in the old 4.125" crank paired up with some new 4.155" pistons for something in range of 447ish cubes. This displacement coupled with a set of LS7 heads, (which I have yet to pick out, but am considering buying GM ones and sending them off to Richard at WCCH) should really take advantage of the Jenvey manifold.
So, if anyone is looking for a Jeff Davis Precision Metal Craft manifold and some Trick Flow 235 heads, Have I got a deal for you

what are the throttle bore sizes on that manifold?
