i said most of those that finish... not most doing the swap. there's a difference
so you are saying Rat had a lockup converter on an LA engine? or was he using a 904/727?
yes the aftermarker K's do handle better. you are referring to the green brick that was over 10 years ago i think... aftermarket K's also can lower the front 1" and allow for a much wider selection of shocks/spring rates depending on intended use. lack of bump steer is amazing for drag racing. not to mention a huge selection of brake packages once you have the mustang II spindles....
the swap is NOT a drop in. crank sensor, starters, flywheels, controls for lockup converters, power steering / pully stuff there are a ton of mods.
it's ok that you prefer the hemi's nothing wrong there but dont try to sell them on people by playing off the expense involved.
