I'm guessing that none of the members so far have Big Blocks. Then hypothetically speaking, if you had a Big Block, which one would you have, and what would you do to it?

in the '79 im still thinking about going to a big block. maybe just a 454 but might go as large as 540. but the Caprice im thinkin about going old school and finding a 409 for it  i know you can get more power out of a newer style big block but man they are just too cool. |

I've got 2 454's sitting in the storage shed. Saving them for something later down the road. One is a 1970 "512" block which is correct for a 454 chevelle or other pass. car. ( I used to be real heavy into SS Chevelles). Anyway if I was to build one on a realistic budget I would build a 496. Just a 454 with a 4.25 stroke ( vs. 4.00) Nothing high $$ or trick. Almost like the 383 is to the 350. Just adding a 1/4" longer arm.

I agree with you on the 496. This is what I would build. Raymond |

Hey Raymond
Alex posted pics of my two 70 SS's on Lt1 tech, if you are intrested in seeing them. I guess not too many on that forum were intrested in Chevelles. The silver one was a 454 car & the red one was a 396 car. I am still friends with the guy that now ownes the red one. He takes it on Hot Rod power tours. So I know it is in good hands. I love Chevelles, just had a series of brain farts when I sold my 70's. I sold the red one in '98 & it is now worth twice what I sold it for! I had more fun in the silver one than any other car that I have ever owned. It had a 482" bb th400 3600 converter with a 4.88 12-bolt.
I could'nt keep gas in it @90cnts a gallon much less $2+
a gal.
AAron- If you value the handling of your Z, I would'nt recomend swapping a BB. Swaped one in my 78Z many years ago & regretted every minute of it. If you do that swap it would be essentional that you get as much weight off the front end as possible. (alum. heads etc.)
I did miine before aftermarket aluminum heads were common, so the car was real nose heavy. Build a nice 406sb & you will be good to go. Just my opinion though.

Scooter, let's post those Chevelle pics here. I need to scan the pics I have of my '67. I'd love to post those pics. Easily the nicest car I've ever owned! I wish I could show you guys the pics right now.  I need a scanner! Raymond |

Russell, Whenever you want to grab a photo that's already uploaded to the internet, just right-click it, then click 'properties'. The new window that pops up will have a line which will either say 'image address' or 'image URL' depending on the browser. Just copy that address (www.blah blah blah.com/picture.jpg) for a direct link to that photo. Then you can put the ![]() and [/img ] tags (*use no spaces*) on either side of the link to embed the photo into your posts at forums. For instance, since I put all of your car photos into one large image, this is the direct image address for your car photos: hometown.aol.com/alex94tagt/images/scooters%20cars.jpg |

Russell 406s outta old 400 blocks arent to great. now if i get an aftermarket block yeah but then you got big bucks. and if i had that id just get a LQ4 outta a Escalade and drop that in there with my T-56 |

As long as the block is in good condition, this is a great foundation for a big cubic inch small block. A buddy of mine has a destroked 400 (377 cubic inch) in his daily driver, and runs 9's. |

I agree with you AAron. They are getting hard to find. 15-20 years ago no one wanted them because of the overheating myths about them. Now everyone wants one. I have one out there with my 454's that I may build for the vette someday. The weird thing about the 400s is the 2bolt blocks are stronger than the 4-bolt blocks.
Anyone ever think about building a small displacement bb? I was thinking about that the other day. Combine the breathing ability of the bb with some of the rpm potential of the sb. I know that Reher-Morrison experimented with the idea back in the 80's combining the bore of the 396 with the stroke of the old 409. But that was back when pro-stock was limited to 355ci.
I just think that it would be cool to have enough money to build all kinds of diffrent engine combos just to see how they would run.
I also thought about a 327ci LT1. 327's have always been screamers.
Anyway sorry to ramble on.

be easier to make a 302 LT1 using an L99 crank.
as to the BB the 396/402 can be screamers i have a friend with one that will pull hard to 6600 RPM. just use a 396 crank with a big bore

Nice to see a message board with a big block section. I love big block Chevys, but for some reason they seem to be the forgotten motor on many message boards.
I currently have 5 BBCs ranging from 427 to 572.

I don't have that many motor pics. And I doubt they're worth another thread. Here's a pic of the aluminum 572 with a 502 just out of the picture...  |

Fasglas: What are they going to reside in? The 572 is a spare motor for a pro street 1958 Corvette. The 502 was going in a 1968 Chevy shortwide pickup, but now I think I'm going to put a small block in the truck. So the 502 is an orphan for now. is that a 1050 Dominator on top that 572? Yes, actually that's a 1250 dominator and a Sonny's CNC intake in the pic. If you look closely you can see that the intake and carb are just setting on the motor and not bolted down. Under the intake there is cardboard and masking tape to seal the long block and keep it clean till an intake is bolted on. The long block is complete and that's probably the intake and carb that will go on it. |

I currently have 5 BBCs ranging from 427 to 572. My first car was a 71 Camaro. Had the good old SBC 307. Now to just get another 71 and a 572 !! |

Now to just get another 71 and a 572 !! That would be a fun ride. I don't know why so many people are overlooking the BBC these days. If you're all about being quick in a straight line, a frisky BBC is hard to beat. Some folks end up pouring tons of money in a small block only to get a butt spankin from a big block at the dragstrip. And if you still want to go around corners and have the extra bucks, an all aluminum BBC weighs in considerably less than a all cast iron small block. Heck, a cast iron BBC with aluminum heads and aluminum intake weighs only slightly more (about 15 pounds) than an all cast iron small block Chevy. Swap the cast iron BBC block for an aluminum block and lose about another 120 pounds. Of course you'll never get a BBC to be as light as a all aluminum LS1/LS6 motor. But it's not hard to build a peppy BBC street motor that will mop the floor with a LS6. Big Block Chevys also love to guzzle nitrous.  (putting on flame suit) ;D |
