I have an opportunity to purchase a car with 400 cu.in engine that has been stroked and is now somewhere in the vicinity of 450 cu.in.. It supposedly was built right and has a mild Hyd. cam and other improvements when put together. I am aware of the 400 engine in the Cordobas back in the late 70's but never heard of anyone hot rodding them. Are there any inherent shortcomings with the basic 400 engine that would make it a problem going forward? I can't find much info on the 400 anywhere on the internet so its hard to find out if it was a problem child or a good solid engine. Thanks, Butch

Good info! I'll find out more about what went inside later in the week and respond back. The builder said it as a great combination but I no nothing about 400's. Thanks, Butch

Wow! This is great information guys. Looks like if it's built right this is a great engine to run. I'll be looking up more articles on the internet and really appreciate the leads.

the original idea for the 400block/440crank stroker engine wasn't really a gain more cube kinda thing. it was easier putting the "B" block into A-bodies, rather then the 3/4" taller "RB" block. header clearances especially. 11 cubes gained over a 440 really isn't that big of a deal. did this engine have the 440 mains turned down, or did somebody bore out the 400 main caps and saddle area (cheaper $$)? that would make a huge difference IMO.

just finished one and put it in my Challenger in october. A friend has an original 68 Dart 383 car with a 451 and runs 11.3 with no tuning and 3.55 gears. here, read this topic called 451 Manifesto .. http://www.moparts.org/Tech/Archive/bigblock.html
I wrote the 451 Manifesto about 10 years ago. I think most of that information is still valid but it is getting a bit dated. More current information is available in my book which just came out this past summer.

I know of two 400's stroked to 451...one was in a 70 charger and ran 12.30's without much tweaking and very little done for weight reduction. The other was in a dakota P/U and ran 11.70's all day.Quite a nice setup but I lean towards a stroked 440 myself

I have a 470 Indy crate motor based on a late model 400. It seems to be a good build. I am a novice at putting together a race car but the first pass at the track it went low 11's. If you need the part list on it shoot me a fax #. It makes 610 hp by the dyno on pump gas.

I know a couple NSS engine builders who actually prefer the B (383,400)blocks to the RB's (413,426,440). Damon Kuhn being one of them (Diamondback Racing Engines) What you have sounds like a good set up. Go for it!
