Which flexplate should I use with c-4?
 

I thought I knew what I needed but after buying a used flexplate I'm coming up with conflicting info/results. Here's where I am so far. I'm using my '88 5.0 and I want to install the C4 that I just built. According to one of my parts sources they're telling me that I need the 157 tooth 50 oz flexplate. That's what I thought I bought but after counting the teeth I found out that I bought the 164 tooth flexplate. When I hold this flexplate in the bellhousing of the C4 there isn't a whole lot of clearance but as far as I can tell it looks like the starter wants to mate up with the 164 tooth wheel. Can someone point me in the right direction? Thanks.

You need to get the B&M flexplate made specifically for this purpose. Using an older, smaller flexplate will not work, as you already know. The B&M is made for the post-'82 5.0L's and C4 autos. Can't remember the exact part number, but you should be able to find it online. I did. Think the URL is http://www.bmracing.com

BTW, the starter should work OK. I had to fudge around with starters for a while to get one that would work with my headers. :mad: I'm pretty sure almost all small block Ford starters have the same gear tooth count on them. At least the bendix for them is all the same one!

Thanks Capri306. I found it in Summit for $105. Figures it wouldn't be the cheap one.
