Can one be turned down?
I've read of people having the bushing turned down on a brake lathe?Can one be turned down?
Thanks for bringing this up - I haven't been able to locate the bushing I'd purchased from JEGS yet (found the invoice, not Brewers like I thought), but I have a feeling I'll be needing to order the undersized bushing and I found one online. I don't have anything to measure the hole in the crank, but once I find the standard bushing I'll know if it fits or not.
If it turns out that you need the smaller bushing you will also need to check how deep the hole is drilled in the crank, sometimes the end of the input shaft will touch the crank, just cut about 1/4" off with a whizzer wheel and regrind the chamfer, have seen that a few times over the years.
Well, the crank in my 440 6bbl is factory ready for the input shaft, and there was a bushing in it, so I replaced that with a bushing, as part of my initial ownership "fixing things" routine. The 18 spline "Hemi" 4 speed behind my 440 6bbl had a mixed bag of wrong parts and fasteners that made up the Hurst Competition Plus shifter that came in the car when I bought it. Per Wayne at Brewers, it was the wrong year, I found regular hex bolts holding the mounting plate to the trans where tapered bolts belong, and this all started because shifting was an ambiguous experience similar to stirring a bag full of wet soupy diarrhea filled with nuts and bolts.......What's the majority opinion of using one of the bearings instead of the bushing? Brewer has the standard bushing for $5, and the roller bearing for $20, so I figured I'd order both. If the bushing fits, and the crank hole is the proper depth, I'll go with that, but if not, I'll have the bearing - but I'll still confirm the depth of the hole to make sure the trans doesn't make contact. The undersize bushing is the same price as the bearing from a different vendor - is that preferred over the bearing? They both have their supporters, it seems.

THANKS! It's kinda funny that the "horsepower limited" FiTech is on the big block, and the far more flexible F&B systems are on small blocks. I asked FiTech if the HP limit could be increased by changing injection components etc and they said "NO" but I know the F&B system is fairly easily upgraded.No, its an F&B system with a FAST EX 1.0 controller system. I also have a 440 EFI 6 Pack using a F&B system with a Holley HP controller system. I recently installed a Fitech 6 Tri-power on a 69 Ply Wagon with a 440 but have not got it running yet.

Well that is not "just a SB", makes over 500HP...
It happens a lot w/me because it's difficult for me not to ask about or offer comments on "something" off topic that may come up in a post or thread, like several 6bbl EFI units belonging to one person.If we could get back on topic
