The sbc offers good power per dollar. But there is no replacement for displacement. I just upgraded my bottom end (and only the bottom end) from a 427 to a 496. It made a REAL positive differance. More torque and more streetable. Only wish I went bigger.

I am running 327. Small blocks are what I grew up with(all I could afford). I would think If you want a cruiser that sips on gas "Straight 6" with OD. If you want a budget performance engine then "Small Block". If you want Max HP and Torque then "Big Block" nothing smaller then a 496.

BBC vs SBC

As long as it brings a smile to your face its works for me. I love the 427 but the more I think about it. I am going to keep my sbc in 1st gen and buy a 69 pr 70 and stuff a bbc in it. I think that is my preference today, LOL. My 70 Chevelle went from 355 to 427 and best change I ever made to it. My 64 Nova handles great and corners awesome with the sbc.

Just replaced my AFR headed 11 to 1 383 with a correct L78 396. Horsepower wise they are both about the same, but I get more looks and comments with the big block. Something about the solid lifter clacking and the deep rumble that gets your juices flowing, if you know what I mean.

Size Matters

Although I am sticking with my Mark IV 454, and will only replace it with a 502,
I have a 350 on stand-by.
The Big Block takes up more room, although it does fit.
A cowl hood is pretty much a necessity with the Big Block,
for both carburetor clearance, as well as heat removal.
Headers are a problem with the original steering box placement.
There are millions of small blocks out there,
and plenty of parts to make them spin quickly.
Overall, I gave up on cornering with the Big Iron Block and Heads.
An aluminum 427 would be a dream come true for me, but the aluminum LS engines are the wave of the future, although if I had one it would be carbureted.
No More Computers For Me.

I know the thread is a bit old....

I think it all depends on what YOU want to do with the car. Keep in mind I was 20 or so at the time, and trading was the only way to get great parts. Years ago I ran a 71' chevelle. I had a very well built high horsepower 383, and I had a mild 396. At the track the 383 would make faster times thru the 1/4 than the big block. but at the end of the 1/4 the 383 was almost out of power. When I would run the 396, it would still be pulling like a sob.
When I wasnt racing on the track, I kept the bbc in it. It was a whole lot more fun than the sbc. Girls love that feeling when you take off, and it takes their breath away....:rolleyes::cool::D:devil:

Personally, I love the sound and feel of a bbc. Nothing like it in the world.

Just finished installing my BBC project this year, had SBC's before, wanted to try a BBC for a change. I used a TCI clip and even with the BBC in it, I still have more room to work than I did with a SBC in the stock shock towers. Engine is .030 over, balanced w/ roller thumper cam.
