I think half of the chev small blocks ever made have been exported to Australia to replace our aging Australian V8's
 , you're getting your own back with stealing our late 60's to 1970's muscle cars now though

Check EBay. There's always 400s listed. I search under "Chevy 400". The down side is the prices are high. If you aren't in a hurry, I would wait until next Spring and hit the swap meets. Hemmings has listings of meets in your area. I just picked up a 400 4-bolt, crank, and two balancers here for $150.

hehehehe....I know where a few are. Maybe even a 4 bolt. My shop behind my house.
The only way I have found them is just by knowing the right people. The hotrod culture around your area is the best place to find parts for projects. Chris

One of my drivers had one a 4 bolt he was bringing me. I work for a flat bed trucking company. He loaded it up on his trailer and was going to bring on to me. Well he stoped for the night at a truck stop and woke up the next day and it was gone!
  S.O.B! It was just the block and crank.

Hee Hee.
Stealing a 400 SBC??!! For Real? That's a drag. 400s aren't that rare, it's just that racers like them. Yes, knowing people definately helps. I snag them whenever I see one just for rebiuildable cores, but I don't find them to be rare, except for the 4 bolt ones. Maybe it's just the CNY winters and salt that make them plentiful.

I got lucky and found my 4 bolt 400 in a 1970 Impala with a blown tranny for a hundred bucks.
I was also told by a racer I know that he prefers the 2 bolt blocks because the bearing webs are thicker and you can have splayed 4 bolt girdles installed. But if you have to have a factory 4 bolt 400 look for a casting #3951511.

Finding a 400 here used to be fairly easy, now there scarce, last time I looked for one I had to go 80 miles to get it. I used to complain because I could trip over 350`s, now you can`t find one. we have 3 drag strips and 1 circle track, so that explains the whole deal. I do not know how true this is, but I`ve read to avoid 4 bolt 400 blocks, there more prone to cracking in the main web area. far as I know they only made the 4 bolt in 70, 71 and 72. but if your not planning on making over 500 horses, 2 bolt blocks are fine.

Yes sir on the web cracking. And it's never found until the block's been cleaned. More $'s down the drain.
Out here in the southwest, there are things called "Pick-A-Part"s. These are self service salvage yards. Great places to search for the esoteric. Prices are right, in my area a complete engine sells for $185 outright no matter what it is. Transmissions are $75.

I have also heard that the 4 bolts will crack easily, but I have also been told they are no different than 350 4 bolts. The cracks supposedly originate where the outer bolt goes through the web. A die grinder is suppose to clear that up area with a good deburr.

Gee, I put a 1970 400 4-bolt in my 68 Camaro 6 months ago, the crank and heads are mounted with ARP studs, it's got an Eagle 4340 crank, Eagle 6" H-beam rods, an ATI super dampner on the snout, J&E forged pistons,Edelbrock Victor Jr. aluminum heads w/2.08 Int. a Crane solid roller cam/rockers and stud girdles,Victor Jr. intake with a holley 830 carb,it's fired by a locked out Mallory magnetic pick-up dist and Hyfire VII ignition, it's a 4-speed car with the rev limiter set at 7200 RPM's (it' been there several times !) it's a lot of fun and runs like a watch, too bad I'm driving a time-bomb!!!
