Check and see, but the Chevy small block 400 looks nearly identical to a 350. Bored 0.040 over gets you 408.7 cubic inches and you can use any parts that fit a 67-69 Camaro basically as a direct swap.

The 305, 350 and 400 blocks are the same. On the outside. Inside however they are different. 305-350 same crank different bore. the 350 is bigger. the 400 has a longer stroke bigger bore and more clearance in the bottom end to accommodate the crank. the flywheel on the 400 is also a balance plate.
