I get that. There is a big difference between saying you don’t have the money to buy parts and saying geometry doesn’t matter. If you can’t afford to do it that’s not an engine builder issue. That’s a consumer issue
Rod to stroke ratio is not that critical according to the magazine tests years ago between a stock SBC 350, a 383 using the 400 rods and a 383 with the 350 rods.
According to David Vizard, a 0.5" rod change in a high compression ProStock engine makes minimal difference in power. He states low compression engines are affected more, but not a lot. This agrees with the magazine article.
Now if you are building a max petformance engine and you have the bank to support the learning curve, go for it. For most street builfs worrying over this is immaterial.
