I like splayed 4 bolt caps...but that's not factory...

Word!

Yeah I ditched the sbc 400 idea. Without a roller cam, I don't think the 400 would make the torque and horsepower at lower rpms. The thicker harmonic balancer also had me worried. I will build a 383 or do a 6.0 liter swap. I like the stroker kits that Texas Speed sells for the 6.0!

After looking around a bit at rotating assemblies, I can mainly find externally balanced ones that are at a decent price point. I understand that having an internally balanced one would be better, but is there any serious longevity problems with an externally balanced one? This is not going to be a high RPM setup, but one with lots of low end torque. Last thing I'd want is to have to rebuild the engine after 10,000 miles.

I'm not sure what you're asking. If you are using a 400 it has to be external.

Whoops sorry... I was asking about a stroker kit for a 350. Most of the ones I've found are externally balanced. What are the main drawbacks of this versus internally balanced 350s?

Only difference is one is basically a stock 400 crank and the other is a 350 crank with a longer stroke.
