Could a '69 Chevelle be ordered w/ a 454?

'Ya really think, Dan? You're gonna create a firestorm with that statement! Seriously though, that's an arguement that's been going on a long time. 454 vs. 427. It's hard to beat an extra 27 Cubic Inches but it does takes 440 RPM for a 427 to move the same amount of air through it as a 454 @ 7000 RPM. The 427 does have a desireable rod/stroke ratio of 1.63 which makes it a little harder to hurt and decreases piston "rock" in the cylinder which makes for less bore and piston wear. Crankshaft is slightly stronger too with that shorter stroke because short stroke crankshafts are generally SLIGHTLY stronger than their long-armed brethren. I've had many of both (and much bigger) but I've always tried to put the biggest motor together that's financially possible! I'll tell you......I've always been impressed by the Buick 455 and the power that people have gotten out of them.
