You have to change the timing chain cover, no drilling, the TC mounts to the same block holes. I'm not sure if your pulleys and Alternator bracket are correct or not based on the pics.

I have a lot of the parts, 8 bolt cover, think I have a divider, also have a 68 400 4 barrel intake. I might have an alternator bracket as well.

Never thought about selling it, but I might if you wanted it all.
I have a race next week, it'd take me until the week after to round everything up.

Then you get to explain they new CC bill to your wife.
