i need to know if a flexplate is the same as a flywheel.im putting a 1985 5.0 motor in my mav and said to have a 81 through 83 flexplate. im guessing thats a fly wheel. let me know .
corbin, I am putting an 86 roller into my mav that is currently a 5 speed. I want to mate the roller motor up to my c4 auto. Can I just use the flexplate from the old 72 motor and bolt it up just fine to the 86 roller moter?
they said on www.fordmaverick.com you must use a 81 throgh 83 c4 flexplatedue to some balancing problems.when i get my 85 5.0 this weekend ill have to buy that flexplate.
Hey Jeremy, For the 86 5.0 you need to get a different flexplate. You need the 50 oz balance flexplate vs the old 28 oz on the original 302. You can either have your old one rebalanced to 50oz, or get a new 50 oz balance, 157 tooth flexplate made for late model 5.0/C4 applications. I know Ford Motorsports sells them, and B&M does as well. I have the B&M and everything has worked out great (It was cheaper than Ford's, too). The funnest part is getting the pilot bearing out of the crank so the flexplate can bolt up. I got my flexplate from Summit. Here is a link to the page: http://store.summitracing.com/defau...e=bysummitpart&searchtype=both&part=bmm-50239 Hope this helps. I don't know how much of a pain, or how expensive it is to rebalance your old one, but that may be a good option too. -Corbin
I used my stock 1972 C4 flexplate & the original C4 trans with my 89 5.0 conversion. All I did was balance match the C4 fexplate to the AOD flexplate. I ran the original starter as well.
thanks for the input guys, I will likely look into the b&m solution, as my engine is coming out of a 5 speed mustang, and has a flywheel right now, and not a flexplate.
This thread is back from the dead. I am collecting parts, as my mother is forcing me to have my mav running by mothers day so I can take her for a cruise. I just bid on THis: based on what corbin suggested. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2462225361 Please tell me that I just did good!! this is mating to my 86 ho engine and my c4
