which one is it, 50 or 28 oz. flexplates.

[dastang2]

i got a problem, i have a couple flexplates and i know one is a 50 and the other is a 28 oz. how can i tell the difference. i don't see any numbers on them. one has a hole cut out directly across from the weight and it is shaped like the weight too. i think that one is the 50 oz. the other one just has a weight on it and no hole on across from it. does anybody have a pic of their 50 oz. or can they look at a known 50 oz flexplate.

50 will have the bigger of the twos weights....a 28 oz weight is about 4 inch long and the 50 oz is about 7inches long...

 

[dastang2]

they all have the same length and none of them are 7 inches long. they are shorter and i know one of them is a 50 oz. i think one is from an 82. it may or may not be 50 oz. i am not sure.

Well if you don't figure it out I've got a B&M 50 oz. with only 500 miles on it for cheap if you are interested.

it's not for me. i sold a motor and had a couple flexplates for it. it's a roller 302 going into a 77 truck so his flexplate won't work. thanks though.

if its an 82 its a 50oz...81 was the cut off year for 28 oz on the 302.......is there any balance holes drilled in them?

 

[dastang2]

there are a few on the weight on both flexplates.

 

[PIMTOUT]

and both flex plates have about the same size weight? (4 inches)?

 

[dastang2]

yes but one has a hole cut in it directly across from the weight and it looks like the weight
