540 cube 407. September 06, 2011 06:58AM
I know 540 can be done w/ a 4 5/8" bore and a 5.35" stroke. I've been in touch w/ a guy who's done it, sounds like there's a fair amount of machine work involved, the block needs the water jackets filled completly to the top of the block deck (I learned that one the hard way!Sad ). Perhaps Kevin will read this one & chime in.

A C4 block is the ideal block to have.

Call Phil at Riverside, He made mine into a 600 in 2006. It is 4.75X5.625 and is wet sleeved. We ran 4 years before we had to replace the sleeves . It is still running.
