I am quite certain that the flywheel will bolt to either. That's not the problem. What I need to verify is whether the manual trans nose will fit properly into the pilot bushing when the bellhounsing is on to set the depth. I am fairly certain it will NOT FIT. (I would love to be wrong here.) The volcano butt has the bushing at the top of the volcano; the flat butt has the pilot below the flywheel mounting surface. I have all the parts to verify this (I have for some time). Now that I'm out slinging iron in the yard I will do the measurements and put them on wps.com. THAT is why I didn't just build that '58 shortblock up and do a swap. I don't believe it will take the '63 manual trans setup. I know the '63 flat crank will! Can't argue with cast iron. "Spoze-ta" doesn't matter! -------------- next part -------------- An HTML attachment was scrubbed...
