are sb 427's really 427 c.i.'s

[Slick61]

I almost hesitate to post on this topic... don't want to perpetuate the whole BB/SB debate. I fought my way through many of these issues when I was shopping for MY beast.

While I absolutely LOVE the sound of the big block, I had concerns about weight and heat. For that reason, a stroked small block made the most sense FOR ME. Most of the strokers I looked at were punched out to around 408 ci... and the more I looked into it, I found the reasons for that. Yes, you CAN go up to 427 ci on a stock Windsor block (and many do), but it might be pushing it, depending on your intended usage.

I bought a 427 Windsor stroker, only after I found out it had a Dart aluminum block- which is quite stout, and can be taken well past 427 ci if desired. It also has a fairly snotty cam and, according to a few big block owners I know, "sounds MEAN". What's perhaps most off-putting is the whine from the timing gear drive.

As for the sound... setup can have an effect on that. Mine is quite loud with a lumpy idle that barely stays running. My neighbors have all said their windows rattle when I'm in the driveway warming it up. You almost need earplugs driving it around town.

But in the end, I got, at least TO ME, an awesome compromise... high power (612 hp/615 tq) in a lightweight package (car weighs 2240 lbs), with a nasty exhaust note. I can also say I've got a 427. An added benefit is plenty of room under the hood for engine work... the space probably helps a little with cooling too. Good luck with whatever you decide...
