I probably wouldn't do 6" rods and a 4" stroke together but a few Impala guys did "409"s for nostalgic reasons, am aware of at least one that was like 415ci.

None of them set any performance record though.

The idea behind a 4" stroke with 6" rod is crazy with a stock deck height block. It can be done but most won't do it because noone has gone any fastef than the guys with the 396's. Personally I plan on doing a 408 with a 5.85" rod to allow a little more meat between the face and wrist pin. Then either a healthy shot or a blower. It may not go any faster than a car with a 396 but it's defintely not "mainstream". Just sayin.

There was a guy here somewhere with what he called a 408 Lt1 not too long ago.
Had vids and everything.

But like Dwayne said, we haven't seen any performance records out of those types of builds.

A 410+ci LT1 is like a golden toilet seat.

love my 410....but right after i built mine dart released their ltx block capable of 427ci... Dammit... But if i could do it over again i would just build a 502 or other nice carbed Big block to drop in... and not that there is anything wrong with my 410 but for the money i could have gotten something alot bigger and stronger. This setup is much more street friendly though thats why i did it..

Never even made it that far. There isn't enough of a market to cover their cost. At least that's what the report said
