18-spline 833 behind new hemi?

Yes a 10.5" clutch will fit, they even make a dedicated flywheel for the swap as seen here:

(Me thinks prices are a bit high at this seller so shop around.)

Also Quicktime (now owned by Lakewood) makes a dedicated bell housing for the swap. (I THINK that a stock bell housing will work but you might need to shorten/grind the input shaft about .060" to .100" as there is a small difference in the amount the crank sticks out relative to the mating surface.)

Hope this Helps,
