About 1.5 yrs ago when i started building the 78 long box i put in a 12x1/8x10 zoom clutch with the disk, plate,throwout bearing,input bearing from jegs. When i got the clutch kit the receipt said it was for a 88-95 with a 454. With this said is this clutch the same as one for a sm465 like i got ? This clutch feels good taking off in low but feels totally different in 2nd, the pedal releases towards the top. I have about 300 hp, 4.10's with 35's so 2nd gear starts are easy but why in low does it release in the middle compared to the top in 2nd? Any info would be great !!
