I am looking to put a C4 tranny in my truck and I don't know the size cam but it's a bit over mild but the guy that is going to build my tranny said he will put a 2300-2500 stall on it. I have the same question here too. Most of you know what my truck is and that I run a 302, etc etc so any info on this as well? Sorry not trying to take over your thread here but it deals with the exact same thing so thought I'd ask it.
