the 5.7L is actually a 347.8353 ci
the 6.0L is 366.1425 and might be rounded to 367 or 368.
1L=61.02374 ci
Keep in mind the 5.7 LS1 was rounded up to 5.7 L while the 5.7 LT1 motors were more along the lines of actual 350's instead of 347's. I read somewhere that the new LS1's are actually 5.6x engines rounded up :D

yeah, he does have it right...you have to think to, 350 = 5.7, 351 = 5.8...so you cant get it exact using 350/5.7...but it is somewhere between 61 and 62 ci/L

is a 350-cylinder heads interchangeable with the 350 Vorbeck and is a direct swap
Really hard to read that man.

But a 350 vortec is stil a SBC 350 just really nice heads stock and roller cam. Vortex 350 head is pretty common practice upgrade on SBC. Flat tapped lifters and non roller cams also fit fine in vortec blocks for a cheap cam swap. Same as vortec rollers fit fine in older SBC blocks.

No , roller cam to consider
Cam and lifters are in the block. How or why would you need to take that in consideration when swapping heads?
