well maybe not, some one has had to have done this it's seems to easy.

so i was brain storming some engine configurations based on sbc, looking around there are pistons for a 353ci [327 crank with a 400 block 6" rod].

but why not a 400 block and a 283 or 302 3" crank for a 320ci.

thats stock 400 pistons with a 1.433 compression height, and a 6" rod.

now that should work

3" stroke 1.5
piston compression height 1.433
rod length 6
______
equals 8.933


deck height 9.025
- 8.933
_____

deck to piston .092

so with a 58cc head and a .039 head gasket i come up with a 8.9/1 compression ratio.

i have seen sbc 400 engines lately for $250 or less and 283 cranks almost for free. a set of adapter bearings would do the trick.


so wadda ya think?

I like the idea, I am looking in the same basic area for another motor in my V8 car. Its well known short stroke engines will rev higher theoretically, but you must have a matched set of heads along with the right cam to make it work. I am not sure how the 400 block will fair where cooling is concerned. Thats something I would like to know. My 350 runs well and has some good power but lacks the snap found in a well built engine. Keep the ideas coming (IMG:style_emoticons/default/beer3.gif)
