That’s the article I was looking for.

Not sure why they'd want a 400 SBC Laurie?

It must have been a 350. I read this somewhere a long time ago but I can't find that article again for the life of me.  Some people say that once something is on the internet it is online forever. But I dunno. There seems to be so much stuff that was in here in the early 2000's that has disappeared now.

That 400 is a weird engine. There must have been some logic to it. Chevrolet had the 283, 327 and 396. They added the 427 for certain applications. The 307 replaced the 283 from August 1967 and the 350 eventually replaced the 327 after the 1969 model year. For 1970 model year they introduced the 400 small block and so the 396 wasn't smaller than the biggest small block it was changed to 402ci, and added the 454 to replace the 427.

 

Thus for 1970 model year they had 307, 350, 400, 402 and 454. It is hard to see why they had the 400. Sure it was lighter than the 402 but everything it went into was big, which was mainly C/K trucks and A and B body vehicles. It was only a 2 barrel until 1973, but it was a very torquey engine. The 402 did disappear at the end of 1972 model year and after that the 400 was available as a 4BBL. But for 3 model years they had a 400 and a 402 with the 402 being the performance engine.
