Big to Small Block?

"My Chevy's better!!!"

a radio commercial of long ago.

The BBC is not a dinosaur because it is inferior in any way. It is a superior design to the sbc, I think. It is the victim of cultural and political events which made the sbc more suitable and much more plentiful. They should have switched to canted valves on sbc's once they saw how well they worked and the debate would probably have been over.

I love my BBC, if weight is the main issue, through aluminum heads and a glass hood on it, should cut some weight right there.

Forget the SBC. Really downsize: Put a turbo V6 GN setup in it.....

I have had a rat motor since I was 19 years old, the same motor, and I'll NEVER part with it. Right now it's a 489 stroker with ported aluminum heads, and has been sitting in my garage for five years, not having been in a car the whole time. I'll buy a big bitchin Impala to put it in, and I will NEVER sell that motor.

But.... There's this "new" breed of motor, that the General has made, that will go into my current and all other future products, without question. It's called an LS. Latest one, which is what I'll use, has a top called an LS7. Non-canted valves (although, you can't argue with the sex appeal of the coll arrangement of the rocker arms when you pull the valve covers off the rat), and the stock heads flow better than any production head, ever, period. Stock.

It's all a period thing regarding which "technology" is new, old, outdated, etc. If one was really a historic nut, he'd run a flathead and declare victory.

If I was going to drive the car every day, today, I'd put a newer LS motor in it. If I wanted to shred the crap out of the tires, I keep the rat. If I was on a complete budget and didn't want to keep the rat, I'd walk down to the local 7-11 and buy a SBC to put into the car, because they are STILL the cheapest and easiest bang for the buck, you can buy stuff for them ANYWHERE. Heck, I have a Performer RPM manifold in my office that I will NEVER use for an SBC, you can have it for $50. Plus shipping.

Value = SBC.
Performance per ci = LS.
Brute force = BBC.

But go twin turbos, less lag out of the corners. Ok experts whats the weight difference between a twin turbo V6 and a LSx?

388 lt1 with an F1 procharger hell yah

it burns the same amount of dinosaurs

you do what you what

I've got a 88 Monte Carlo SS with a 87 GN Turbo V6 motor. Economy and awsome performance. The V6 replaced the powerful and world famous 305 SBC.

If you want a sbc chevy put one in. Thats what I did to my pontiac. Who cares what the purists say. I would have loved to put an aluminum head bb pontiac, big blocks are cool but the sbc was laying around so I used that. It just made sense for me. All that matters is to be happy with your car, I am. Its fun to have the purists mad at me, little did they know my lemans came from the factory with a chevy 6 cylinder. They will be even more mad when I blow by them.

Running a computerized small-block may be the ultimate for squeezing every bit of power out of the motor and never having to "two-foot" it to keep it running, but I could care less about either.

1. I have never had a car that got great gas mileage, so I don't miss anything with a carb.
2. My carburated BBC makes enough power to get done what I need to and then some--if power fluctuates by a few hp it doesn't really matter.
3. the low-end grunt and "cool factor" alone make it worth running a BB.
4. I have always liked having a choppy idle and a louder car, and I like the simplicity of a carb.

Guess I am a dinosaur just like my engine.
