Anyone ever heard of this kit? A friend of mine who's a killer mechanic told me about this kit. It consists of an offset crank, and small journal 327 rods. IF anyone can point me where to look it would be appreciated. Btw the 400 in question will be going into a 1985 Firebird.

If you have a 400 block, assuming you bore it +0.030" a 4" stroke will go in just fine and get you 434 ci.
If you're trying to get 426 from a 350, it's not happening. A 4.060" bore and a 4" stroke will get you 414.3 ci.
To use any more stroke requires a non-production tall-deck block with a raised cam tunnel and spread oilpan rails. This in turn requires a different timing set, oilpan, and intake manifold spacers.
