Thread: Stroker SBC's using 5.6 400 rods

What I have been reading about is guys buying stroker cranks and hanging 400 rods/350 pistons off them.

Yeah, if you're absolutely broke and have a buddy at a machine shop who will cut the 400 mains for free, this approach should work out for you.
Here's the flip side: I have a great deal of respect for Pat and will have to agree with him on his take on this. Depending on the parts you use to build your 383, you could easily double the hp/torque of the 350 that you start with. Do you really want to do that with 40 year old parts?

Scat makes a cast STEEL 3.750" crank that is under 200 bucks.....
Here's the one for 2-piece seal and external balance....

Use a 400 damper and flexplate
Here's a decent set of rods, I'm sure Pat could do better, but here's a set that's affordable anyway....
5140 I-Beam Rods, Chev SB (LJ), 5.700", Press Pin-Competition Products
I couldn't find any decent pistons, but Pat probably has some on the shelf.
