Any stroker kit would be custom order from one of the Olds vendors that are regularly talked about on this site. Why do you want a stroker. Olds motors make good torque with in the stock arrangement. And if you want more, a 403, or a 400-425-455 will give you more stroke in a less costly manner.

Just throw some parts at it, you might get lucky and fix it.

stroking a olds 350 is somewhat pointless unless you want to make really big power, when it usually makes more sense to build a DX block. if you want to get nice streetable power in the 400-ish range and want more cubes, 403 is the obvious choice.

FWIW, I had my 350 "stroked" by a tiny amount to make chebby 400 rods and pistons work. the 350 gas block can be stroked to decent amounts, IIRC, to around 372 or 380 inches, but mine is already at a healthy 362 inches with a .068 overbore. DX blocks can be stroked to 400-way-plus inches, and has the strength to accomdate the power extra cubes opens up.

To stroke a gas block, you either gotta get custom stuff, or have a standards olds crank turned down.

I'm going with the Chevy 400 internals, for a few reasons, its lighter, easier to get, and best of all cheaper. It would cost me the same amount to get forged olds pistons, rework the rods and crank and still have the stock stroke with the heavy ass internals. Honestly thats the best we Olds guys have, still more than enough to whoop on a piece of **** 383 chevy

Just for the sake of humoring me, what crank would I need to get, which one has the closest journal sizes and won't need to be turned down as much as another one of larger journal size? Thanks.

Capt Jim's stroker is a very nice , well thought out setup. It should give years of trouble free service , and put more power to the ground than the average run of the mill engine.
