Now that they can get a 454 out of a small block and about the same from a LS1 all aluminum engine, what is the advantage of adding all that weight? Valves can be bigger on a big block, but with modern high flow heads are you really giving anything up with the smaller valves?

 

And we don't want pics! :thumbs:

 

Well that 454ci Small Block is bored to the MAX, you damage the cylinder wall and you're screwed. Getting power out a BB is fairly easy and it's reliable. Why do you think 99.99999% of all air boat motors in the gulf south run 454/502 engines? Power and reliability, and these engines run 5K rpms all day long. A Big Block will ALWAYS make more power max power vs max power because if the ci potential and larger/better head flow design. Just ask top fuel dragsters, I bet they wpould love to save weight and run a SB if they could make the power with one, but they can't.

For mild/street only applications, a SB is without a doubt the way to go. :yesnod:

 

That's a very good point. :yesnod:

 

but, aren't they running upwards to 700 ci motors?

i'm talking about the best compromise between handling and straight line performance for a car that will see a lot of touring. Some of you guys here jugde your ride based only on its 1/4 mile slip. I use my car for business trips and put a lot of miles on it and i like to run road courses. Big block parts are expensive. What happens when gas hits 4 bucks a gallon like it is in europe?

At the risk of letting my ego getting in the way...
and inspite of the fact that I don't compete inbrass-nads/heads-up racing...

NHRA Top Fuel, as well as Funny Car and Pro Stock, too, are limited to a maximum of 500 cubic inches of displacement.
IHRA Pro Stocks have an un-limited displacement rule; teams long-ago began running up to, and even over, 700 cubic inches.
Because 'bore-to-bore' spacing can only be increased 'so-much', the resulting displacement is achieved by very long strokes, which keep the maximum RPM well-below their 500"-NHRA counter-parts.

 

No they are limited to 502ci.

Who's Andy Rooney?

Say goodnight DEP

Goodnight DEP :seeya

 

I'm going to have to assume that you are just dumb and don't know alot about Corvettes or even cars in general. This is a stupid thread. Trying to discuss the advantages/disadvantages of a big/small block in dumb general statements is asenine.

 

I can tell you first hand that on a road coarse, it's 90% driver's skill, 10% car. Able to read the curve's apex, knowing your car's limitations, able to go into a corner in four wheel drift and come out and be set up for a straight run, recognize a decreasing radius and cut a double apex.....that said, I raced four years in NCAA events at Nelson's Ledges, Mid-Ohio, twice at Watkins Glenn. In that time, only once did a small block better my time...only because I took one run out of three....I had everyone covered after the run so, I packed up and headed home to check into the hospital for ear surgery the next morning.

Fellow club member beat me that time, first thing he did was call me at the hospital to let me know he beat me for FTD on street tires.


So did I, the first two years of ownership, drove the 68 through harsh winters. Regarding parts, BBC parts are no more expensive than the SB. Set of forged pistons and rings are in the same ball park as SB, same for a 4340 crank, ditto for a cast crank. Bare block is more expensive, but I doubt if a used BBC block will put one in the poor house.

Regarding the gas price....I doubt anyone running a Hi-po motor, BBC or SB is concerned with the gas mileage or the price of gas...if it hits 4 bucks, so what, you go to the pump, fill up, reach into your pockets, pay the 80 bucks for a 20 gal fill up, and light up the tires as you exit......:D

 

Whoa there bro....easy, sit back, relax, grab a brewsky and down a few suds. Think you're missing out on some fun....this thread is not intended to discuss the merits of a BBC vs SB, but a tongue in cheek humorous banter and a parody on Andy Rooney's commentery.

 

:thumbs:

 

Sorry George. I shouldn't have continued replying. I'll gladly plant the hatchet. Just point out the center of Glengages back and I'll let it fly!
:lolg: :lolg: :lolg:

No more...I promise :blueangel:

Dep

 

How about 24" lower, and you can give me a great, big kiss?

 

I thought just having a Corvette made up for it; now I gotta get a big block too!!! Now what am I gonna do???? :eek:

 

I've changed my mind about the clown hat for the blushing2 icon. I thought the red cheaks would look kinda like a clown if we added the sack hat.

Let's make DEP a dead horse icon!!! Would ya use it Dep?

It all started here..........

A retired Cook Co. Deputy decides to try horseback riding, even though he has had no lessons or prior experience. It just seems that a Deputy should
know how to ride a horse.

He mounts the horse, unassisted, and the horse immediately springs into motion. It gallops along at a steady and rhythmic pace, but our Sheriff begins to slip from the saddle. In excitement, he grabs for the horses mane, but cannot seem to get a firm grip. He tries to throw his arms around the horse's neck, but he slides down the side of the horse anyway. The horse gallops along, impervious to its slipping rider.

Finally, giving up his failing grip, our man attempts to leap away from the horse and throw himself to safety. Unfortunately, his foot has become entangled in the stirrup, he is now at the mercy of the horse's uninterrupted gallop as his head is struck against the ground over and over. As he is battered against the ground, he is mere moments away from unconsciousness when to his great fortune.....Frank, the 75 year old Wal-Mart greeter, sees his delimma and unplugs the horse.

Ever since this day when Dep sees a dead horse he tries to beat it in retailiation for that embarrassing day.....................for he knows now that he can never ride off into the sunset but is doomed to ride around Chicago in an airweight big block Corvette with no heater in the cold, cold Illinois weather.

:lolg: :lolg: :lolg: :lolg: :yesnod:

 

uh-oh...Jim has been hittin' the sauce again :nono:

:lol:

Dep...thinks dead horses belong in ONE place only...between two sesame seed buns ;)

 

It is a cool evening here but no sauce, not a bad idea though.

Far as that goes stop by sometime and I'll buy you a drink or two.

I was looking at the pic's ya sent and I wondereed if you were going to rip out the wiper door and canister too? I'd go with a long L-88 hood they are much easier to live with.

When I had the '70 454 BBC Vette I put a long hood on it but I apparently didn't get the correct one. I had to mould the tops of the fenders to match the hood. I wonder if they make one that uses the original door trim?

Car looks nice. It pays to start with a nice body even if you do rip a lot of stuff out. I thought you were kidding about literally ripping those parts out, you weren't were you!

I take the body off of the frame and do a stiffening on it, weld and gussets and maybe that foam like I want for mine.

Gotta go, wife wants to run to Walmart. Can you believe that they took out the horse at our Wally World? :yesnod: Jim

 

Think I may end up getting out my reliable hacksaw on the hood. There's a good chance what I plan on mounting for induction may not be short enough for the L-88 hood. Not sure yet though.

Dep

 

There used to be a piece that went between the hood and the windshield that let you keep your hood and replace just the wiper door. The panel that was stationary and looked pretty good, I see one occasionally. You could remove all of the hardware that was under the hood and in the way and lose a few pounds on the way.

I would go with a Baldwin Motion hood like Woody has on his Motion Vette. It looks good and gives that extra clearance needed for a big induction set-up. That way it wouldn't just look like another old race car but a Motion car. I really like the Motion stripes on a White car too.

I asked why we didn't have a Horse at our Walmart while we were there. Greeter told me some guy in Chicago fell off of one and received serious head injuries, so Wally World had them all took out. Who ever he was he probably got enough money to buy a new crate ZL-1.
