The K3500 splice job is going to have to be a farm out for us (started the quote process) as we just don’t want to be plagued with frame problems after the K30 is built.

Cutting down the K3500 frame should not be terrible, and can be plenty strong (in fact stronger than factory) if done with correct fish plates and a good welder.

That said, when you start getting into multiple cuts and splices, you increase the probability of something going amiss. With the C30 frame, a lot of the hangars and so forth line up with factory holes, which allows you to keep things aligned pretty well.

Either way, what's best is what you're comfortable with. On my last project (as you know) I did the original frame with modified hangars and such. On my current one, I'm building a hybrid frame from a different generation truck and a metric G-body. So I'm not really biased
