I noticed there were basically two designs for the flex plate. The one i pulled from the back of the 5.9L. Round, has a couple of weights on it, its has about 1/2" lip with square holes cut out of it. I believe this is for the crankshaft sensor correct?

Does the one outta the 5.2L engines look similar or, does it look like that star pattern? If the one outta the 318's or newer 5.2L is the star pattern one, where does that crankshaft sensor go?

I'm in the middle of a 360 -> 408 stroker "transplant", and im just trying to work out the last few details. I am trying to track down a flex plate that is neutral/internally balanced that will work with my system.

 

Call Hughes engines

 

the 5.2 and 5.9 flexplates are different. crankshaft sensor goes in bell housing of the trans on the passenger side just behind the head.

 

thanks guys you rock,

I thought i had most stuff covered, but this flexplate and torque converter issue had been driving me crazy.
