Sorry about the info I missed out on: The gears are 3.50 w. a Detroit Locker. C-6 worked to the max by a Ford professional. The car is a ´70 Spoiler.

This is how it works: The feel from the engine is hard to describe, but please do not get me wrong: It puts out a LOT of power. I know how the enormous ports and valves make this engine different from the N-code engine of the same era. It really kisks in hard when it passes 2500 rpms and thereafter it pulls very hard up to around 4.800, where there is a definite flat spot.

I did remove the EGR bosses from the roof of the exhaust ports and very, very gently smoothed the area around the valve stem. I did not touch the floors of the ports at all. I know what that does to these engines.

Still, I seems somehow unwilling to jump from the start when ordered to. It seems almost like it pushes the throttle back and will not get up and go unless wound up to the maximum pre-stall on the stock converter.

I also figured that the 3310 would be lean on this engine, after all it is considerably larger than the Chevy it was originally built for, but still, is this really such an issue that I need to go to a Barry Grant or a Demon carb and a 10-11 inch converter on an engine that idles smoother than the standard original Lincoln 460?

Any thoughts?
