There is a hole in the bell flange on the driver's side below the dowel and the bottom bolt hole. What is this for? It's below the skirt. Nothing that O know of on a FE is below that? The metal on the outside of the hole interferes with my headers so I will need to cut it off. Nice, cutting a new $900+ bell. The old Lakewood bell didn't need cutting.

I suspect it's for alternate clutch designs - hydraulic cylinder mounting or cable clutch stuff. Those guys probably appreciate it being there, but us old school guys just trim it off.

That makes sense, selfish me for thinking they made it custom for me ;)

Keep in mind that self modifications to a SFI bellhousing will void the SFI certification, per NHRA. That includes minor “trimming”. Technically you are supposed to send it back to the manufacturer for any modifications. For the little bit you’re talking about no tech inspector will probably notice, and even a lot of “picky” tech inspectors might notice and not say anything, but I’m just giving you a heads up. Do lots of racers do something similar?, sure. Will that little trim weaken the bellhousing?, probably not. But it’s an expensive part, I’m just giving you a heads up first before you touch it. You may also want to consider if you ever plan to send it back to the manufacturer in the future to be re-certified, some manufacturers are picky about re-certifying a modified part. I’m not a tech inspector, but I know NHRA has covered this in the National Dragster in the past. There are authorized companies that modify bellhousings for removable clutch adjustment covers, you may want to ask them, or the QuickTime tech dept. Again, before anyone flames me, am I possibly being overly alarmist?, sure, but a lot of people that don’t race a lot don’t realize this, it’s just something to consider before you start to trim.

That hole is for a cable actuated clutch.

Thanks for th heads up Kevin. I doubt I'll ever need the SFI. I only bought it because Holley didn't have any non-SFI in stock and they expected it to be mid to late May.................maybe? I am a little impatient at times :-)
