What I found in that thread ..
Turbo 4.0 engines put out masses of torque ... The MPH is often low on these engines [compared to E/T] YET the E/T is low ..
The calaulators are mainly set up for N/A or supercharged engines..
Turbo engines with decent set up and tune, gearing make "HEAPS" of torque...
The quick way these engines down the 1/4 is get the engine loaded as quick as possible.. Which an auto does. Esp a Powerglide..
The ladder bar rear suspension helps BIG time with 60 Ft times ...
If I read it right the E.B manifold has been ported between each runner..
This is done on Edelbrock V8 manifolds where they shorten each tunner and makes plenum larger as a result.. If I read it correctly...
So there's two majer mods that not too many have done..
Which is common practise if it was a Torana etc..
