And Pontiac and OLds have even longer stroke. That's the beauty of the 455 Buick, shorter stroke AND it still makes the most torque!
OK you are right, i am wrong [oh my] as penance, i actually went and opened up a book:shock: buick 455: 4.3125x3.900 b&s with 360 developed hp @ 4600 rpm, 510ft/lbs developed torque @ 2800 rpm. chevy 454: 4.251 x 4.000 b&s, 360 hp @ 4400 rpm, 500 ft/lbs tq @ 3200 rpm [based on 1970 hp engines with 10.0-1 compression for buick and 10.25-1 for chevy]. you can read into this what you like but i think the important info is where the torque curve and the horsepower curves meet. the chevy has to rev quite a bit higher than the buick to make its power. one of the reasons chevys with 4 bolt mains are highly sought after is because they need to rev up quit a bit and need the extra support to keep from flying apart :error: by the way, buick 350s made 315 hp @ 4800 rpm and 410 ft/lbs tq @ 3200 rpm. chevy 350s made370 hp @ 6000 rpm, and 380ft/lbs @ 4000 rpm. and just for schticks and giggles, the caddie 472 made 375 hp @ 4400 rpm with 525 ft/lbs tq @ 3000 rpm with a b&s of 4.300 x 4.060.:3gears:
i'm sure someone can chime in with a dead-on answer, but all i remember is that they're pretty heavy. a 401 or 425 is about as heavy as a BBC (a little under 700 pounds), i think.
gregs mama, a diet coke, and a snickers bar:3gears: sorry greg. most of the early 60s engine blocks were pretty heavy. it was the high tech of the time. the ford 401 to 428, chevy 409, buick nailhead, mopar boat anchor, they were all pretty heafty.
yeah, didnt fart, furd, floord...in the one upsmanship game of the early 60s, in order to compete in drag racing and maintain the 400cuin limit have a 401 based on the 390 fe block? that grew into the 428 and eventually the 460? what do i know, but i seem to remember reading about that stuff. along time ago:sleep:
i think they had a 406 for a short time too. things were moving pretty fast back then. but by 65/66 all the old blocks were becoming obsolete. that is when buick came up with its 400, chevy came up with its markIV [396] ford developed another block that became the 429 in the cobras and mustangs [boss] mopar came up with the 383/440 block, and pontiac and olds just punched out their old blocks to bigger cu/ins. AMC didnt get thir 401 till 70 or 71, i think. all i really want to know is...why did ford have so many engine familys?
I know......351cleveland........351windsor........351modified.........by the time I finally knew how to tell the difference, I was out of the business! :grin:
Ford seemed to start with one engine and keep adding cubic inches to it till they had some pretty monster sized motors. The FE's were 352, 390, 401, 427fe, 428, and I think a 402. Then there's the Cleveland which became the 351M and 400M. The The 385 series had the 429 and 460. Part of the reason for so many was age of the design of the engine family. Some designs kept getting punched out to bigger and bigger engines. Others existed only in certain cars, some in sports cars, and some in trucks.
Let's see. Boxed convertible frame, sound deadening, metal inner fenders, typically has either A/C, PW or power seats, or all. Doesn't take long to weigh 500 lbs more than a Chevelle SS.
