They are not really that expensive considering how important they are. Quote Selected

"4x4 have the center sump design not the 4x2"(2wheel drive). in 1982 ford went to the 50ounces counterwieghts on there small block 5.0 and 5.8.so all i'm saying is. keep the flexplate thats made for your "year of engine block and crank". if it a 351 out of a 85 bronco ,then it 50oz flex plate and it will go to your 1982 3.8 c-5 tranny. the c-5 have more clutch's in the clutch packs. inside the tranny that why the factory calls them c-5.the AOD had the lockup torque converter not the c-5. the AOD came out in around 1981.yes ,157 or 164 make a difference. because that what starter and tranny/block plate you will re-use. so just reuse the starter and tranny/block plate and flex plate from your bronco 5.8 should be ok.

351 W install Reply #21 – December 04, 2008, 12:19:13 PM I just noticed something. The old flexplate looks like a 50oz? I counted the teeth its a 164 tooth. Could this engine really be a 302? The guy I bought the truck from said he replaced it and put another 351 in.Pictures belowhttp://nebraskathundercats.com/engineswap/flexplate.jpghttp://nebraskathundercats.com/engineswap/engine1.jpghttp://nebraskathundercats.com/engineswap/engine2.jpghttp://nebraskathundercats.com/engineswap/engine3.jpghttp://nebraskathundercats.com/engineswap/engine4.jpghttp://nebraskathundercats.com/engineswap/engine5.jpghttp://nebraskathundercats.com/engineswap/engine6.jpgPics of bronco before engine was pulledhttp://nebraskathundercats.com/engineswap/oldpic1.jpghttp://nebraskathundercats.com/engineswap/oldpic2.jpghttp://nebraskathundercats.com/engineswap/oldpic3.jpghttp://nebraskathundercats.com/engineswap/oldpic4.jpghttp://nebraskathundercats.com/engineswap/oldpic5.jpghttp://nebraskathundercats.com/engineswap/oldpic6.jpghttp://nebraskathundercats.com/engineswap/oldpic7.jpghttp://nebraskathundercats.com/engineswap/oldpic8.jpg Quote Selected
351 W install Reply #22 – December 04, 2008, 01:11:43 PM these a casting number on your block on the passenger side down by the oil pan, where the starter was. that casting number will tell more about the block.also messure the from cylinder had to cylinder. the 351 is wider than a 302.

351 W install Reply #23 – December 04, 2008, 02:10:34 PM Got a pic of the area where the distributor mounts? If so I can tell if it's a 351 because it will have some *supports* cast into the block that a 302 does not have. Quote Selected

351 W install Reply #25 – December 04, 2008, 11:07:54 PM On a 351, you will also be able to get to both waterneck bolts easier, because of the taller block. On a 302, one bolt is almost behind the timing cover.:D Quote Selected

351 W install Reply #28 – December 05, 2008, 05:28:19 PM not to hijack this,but I need a few answers.as I mentioned in my post,I used the 164 tooth flexplate from the 1983 3.8/c5.is my flexplate a 28.0 oz or a 50.0 oz?also,shouldnt the harmonic balancer match the flexplate, as far as the oz's? the only reason I used the FP from the 3.8 was to save on money and I figured if it doesnt work out,then I would spend the money needed to correct it.The car drives just as it did when it had the 3.8 in it,other than the extra HP.can someone clear this up for me?
