This gets into engine design a bit. Over 25 years time, builders found that

the 327/350 Chevy rod journal size ( 2.225 dia x.944 w) coincidently was

better for high-speed heavy load (eg, racing) work, than the 351C Ford size

(2.3107 x .824 w), while the Ford main bearing size was stronger than the

Chevy. It's interesting that the total surface area of both rod bearings are

very close, but the wider Chev size seems to be better for speeds of 6000

-9000 rpm. Remember, the engine doesn't know (or care) who built the

components. And because they built a bazillion SBChevs while 351Cs were only

built fm '70 to '74, demand for Cleveland stuff is non-existent by

comparison. Oh, well... J DeRyke
