If that is the case listen to this. I looked at the head casting numbers and I am sure I have a big bell 6. The trans bell on this does not look right, and from what you told me, it is a small bell on the tranny. Heck the starter is right under the exhaust manifold. I can feel a couple of bolt holes in the block right below the head on either side. This is where I am assuming that the Big Bell would bolt on to. But lower than that and in tworards the middle a little is where the top bolts on the bell that is in there are in the block. Is it possible that someone drilled and tapped new holes in the block to take a small bell? And if so... Would a small bell from a 4cyl 4 speed bolt to it if that bell is the same as the small bell that is on the c3 that is in there? Mass confusion going on here. But if the small 4 cyl bell will work, hey I can go with it. The only tranny i cna find around here right now.
