Originally posted by fastTA I am definitly not a sbc expert, I have been focusing more on LT1/LS1 motors, but I believe it is a 400 bored .030 over.
Which would be a 4.155" bore x 3.75' stroke I think.
Correct.
My cousin used to have a Monte Carlo SS with a 406 in it. Edelbrock 4BBL on a performer intake with Corvette heads, headers and true duals.... It haulled butt, and sounded wicked!!

It's a 400 SBC bored .030 over - check this link out- http://www.proautoinc.com/406.htm. Don't confuse it with a 400 big block though (actually 402ci but marketed as "400").

That link didn't work for me. What is the stroke on the 433?

A 400 SBC bored .030 over is a 406.
To get 433, you would need to change the stroke by replacing the crank.
