A small block will never compete with a big block power wise.As stated earlier in this thread torque destroys drive line parts.So be prepared to spend some money on everything behind the engine if you go with the big block.600 horsepower with a big block will be much easier and cheaper to build.Have fun making your mind up!

 

I'm not debating SB over a BB, just saying the right SB can spin high rpms repeatedly and still hold together. Case in point, 302 on the Z/28 which would spin 8+rpms on the race circuit.

 

Roger that.

DO MA NEU!

 

Most people have SBC why the majority don't have 600 hp. BBC types if you have 600 hp they start asking whats wrong with your engine is it only running on 6 cylinders.

If you want a real good laugh put your bare BBC on its bell housing flange standing up then put your SBC up beside it. Look at how thick the main webbing and caps are on a BBC look at its cap width and all its depth, the SBC is a joke by comparison. Having 4.84 bore centers compared to 4.44 centers makes for a lot of difference in strength.

 

wise choice

 

True.........SB is the way

 

I guess the majority of the people on this forum with big blocks better start looking to get their motors fixed. According to you any BBC with less than 600hp is unheard of in the corvette world or any world for that matter.

Don't get me wrong, I love the big blocks as much as anyone. But they are not the magic cure all for corvette's, or any car that you make them out to be. If it makes you feel better to go around telling everyone that you have a BBC in your car, then that's your thing. To each his own.

 

Most BBC in question have not been completely rebuilt, only freshened. Basics performance cant be addressed with "freshened". Then the ones that do get rebuilt, are by who? Not everyone knows what goes into 550-600 hp street builds...

 

I don't think it was meant as an insult; just a clever way of saying "it's easy to make big power with a big block".

Any small block guy who thinks otherwise is kidding himself.

 

Good choice on the Mark Jones/Vortecpro engine...

You'll be breaking rear ends and trannies for fun now.

 

First 10 seconds are with a small block. They put a big block in at 30 seconds:

 

whats the problem

 

looking forward to it...

 

When you put up your silly little BS flag what i said about a 496 making 600 hp out of 496cu. anybody could do it is true should they want to or even more power and the engine can be completely reliable without aftermarket blocks, also do it without after market heads. At this power level you could make the BBC cheaper then you can fortify a SBC to make the same power and it still live. Now if you build a 396/427 BBC 600 hp would be much harder.

A 496 stroker has become an average build for a BBC today just like the 383 stroker SBC has become the average build both for people that don't have cubic money to use. Question is to you if you want that 600 HP, its worlds easier to do in the 496 then the 383 and far more reliable, with more torque everywhere.

To use don't put a BBC in the vette because of the weight still stand behind what i said a non player in a vette. Now if someone had a camaro with a SBC that already has bad front to rear balance problems. If someone were to say i want to put a BBC in it, i would be one of the first to say unless you have a real need for the extra power you should do a SBC build. When you set your hind end in a vette all your body weight is setting very close to the rear axle, even if your front to rear were 52/48 that changes closer to that 50/50 you want, if you had a vette with 49 front 51 rear, you get in the car or have a passenger Lets say you weigh 190 have a 110 lb passenger, you have now placed 300 lbs very close to your back axle. What does it weigh now front to back ??? regardless if its SBC or BBC


the only total BS thats on this forum is don't put a BBC in your car will make it handle bad.

 

Ya, IF handling really matters, get an ls1,2,6 takeout and throw a cam in it. Light, good useable power. Wouldnt mess with sbc abymore, BBC or lsx.

 

Long as it's a manual shift car I can live with either

 

And if you want a bigger laugh, put that production big block next to a Bowtie or Dart/Brodix aftermarket block. Splayed mains, half-inch bolts, more beef everywhere.
It'll cost ya though!

 

With todays power availability almost any motor can be too much for the frame and rear tires.

The limit is the pocket / wallet, frame and the rear tire size.

What was once a dream as far as HP is now a click away.

572 and 800 Cubic inch motors are readily available. HP can be from 500 to 1000+.

The real question is how are you going to use the car and which engine choice is best for that use.

I agree an LS motor is a fantastic choice, but old school motors are easier to repair. Some of the new LS motors are over 900 HP.

What ever you're choice enjoy the ride, it's great with either size / kind of motor.

 

Unless you sink a lifter, pretty much everything is easier on an LS... not as cheap, but easier.
