Just a heads up hopefully I will save someone some trouble. The Quicktime SFI Ford FE to C4 bellhousing will not fit a case fill C4. The Case fill neck bumps out and the back of that bell is a flat plate that hits it. I never read this and if it was on the Jegs description I apologize. I waited for the bell on backorder for 2 mos. Anyway with some grinding on both trans and bell it will fit but a shame to grind on a nice bellhousing like that. I should've bought a pan fill but I lost patience to ship the trans back for the different model. Hope everyone has a great weekend!
Since Holley bought Quicktime a few years ago, the information about their bellhousings has become rather sparce (to put it mildly). I ran into similar undocumented problems with a Quicktime FE to AOD bellhousing a couple of years ago. The big issue was that the Holley tech line said the stock AOD 12" converter would fit, it does not, you need a custom 10.5" or smaller converter, not ideal when wanting to use a converter with a low rpm (< 2000) stall behind a very torquey, built 390.
