Hi, i am still looking for the right flywheel for my 3.0L engine, and was wondering if i really need a 10LB flywheel, is it really a necessity, i know it felps off the line takeoffs, but it lets engine rpm drop faster between shifts. I honestly can't afford to buy the one that MSA sells, it is too much and the one from Arizona Z is my next choice, but would like to spend only around 150-200 for a decent one. Is there any year z that has a lighter one which will work with my setup? F54 block 1980 5speed. I also know that i can have a slightly heavier flywheel be getting the lighter/smaller 240 crank pulley, is that right? Lastly if anybody has a flywheel for sale that is farely light, around 10-20Lb range let me know.
