Question EFI conversion & Flexplates

I was wondering if any of you guys that have done a conversion have had or have heard of issues regarding different flex plates.

What I am doing is a 95 5.0 HO swap into my 73 Bronco with a C4.

My question is this. When reading through a bunch of different articles I ran across one that stated that the weights and or balancing on the flex plates was different and possibly the tooth count also. but for the life of me I can not find were it was at. Have any of you heard or know anything about it? Something like 27oz VS. 50oz of ballancing.
I am switching the computer, Mass Air, and distributor over to a 93 with the A9L computer. I will be using a RJM harness along with the HP and LP Carter pumps.

Also, I found someone with two T3 turbos they were going to use on a custom TT foxbody set up. I may grab those and build my old block for a twin turbo set up, has anyone heard or seen this done?

Any and all input is welcome

Yes there is a balancing difference between the early 302 (28.8 oz) and the later model 5.0's (50 oz).

I haven't dealt with the 5.0 to C4 myself, but everything I have read says that the 89-93 Mustang AOD flexplate has the same bolt pattern as the Bronco C4. This seems to be what everyone is using.

Good deal thanks,

It sucks that I have to change the flex plate put at least I found out prior to starting it up.
