Get a SAE belhousing from an old C70 Chevy and bolt the 454 to the 5spd overdrive that's in there.
I would really like to do this myself, just heard stories of 4mpg, now if it would get 10 mpg
Sorry, I know next to nothing about disk brake kits
Careful on that- one of those bellhousings is how I swapped a 427 tall deck in my M715 with the 3053A tranny, BUT...not all of the 366 & 427 (6 & 7 liter...or ealier SBC versions) had the correct bellhousing. Only certain ones are dual pattern. One pattern is for the big Dana (typically) 4 speed that was behind them that bolts TO the bellhousing in traditional fashion and the other pattern was 5 thru-holes that will allow the deuce tranny to be bolted to the bell from the inside or clutch side of the bell into the tranny. MOST are only the Dana pattern. If one is to find a dual pattern bell and wants to do this swap you also MUST get the plate that is in between the bell and block. (!!!) That plate allows a very large flywheel and 13" (same size as stock duece multifuel) clutch. Yeah...so if you want a real truck clutch...grab the flywheel too from the bell donor. (!!!)
IF you're going to run a 454, they are externally balanced and the ONLY one of the first Gen BBC's to be external balance. You will need to get an aftermarket balance plate to sandwhich between your flywheel and crank flange to make the balance correct or have the engine internally balanced and pay $$ for malory metal in the crank...oh, and buy a new internal balance harmonic balancer too.
Also, for what it worth, the 427 (&366) tall deck is a heavy duty version of the big block chevy. Few 454's came through in heavy duty for so the lion's share was cast crank, sufficient rods, cast std 3 ring pistons, and 2 bolt mains. ALL 427 & 366 tall decks had steel cranks, heavier duty rods, 4 ring diesel looking pistons w/ heavier skirting, and FIVE 4 bolt mains.
Oh, one other thing- IF one goes this route it's possible to mount the engine and transmission three point style like that factory engines are by using a truck mount under the harmonic balancer then use the mounts on either side of the bellhousing. Fairly simple, yep. Get in the way of your PTO to the front winch? You bet'cha!
Just keep it in mind when designing the driver's side rear/side mount at the bell if one goes that way. On my M715 is used a more traditional civilian light truck mount and did the two side block mounts then built a rear transmission mount. I had to cut a portion of the truck bell's driver's side mount off to clear the PTO shaft coming off my 3053A and stock deuce PTO to drive the winch up front.
