Hi all! New to Suburbans and Panels. Coming over from the short wheelbase side, hence the name.

I just picked up a 71 K20 roller (Pictures coming soon) without a SPID and I'm wondering what engine/transmission it came with. Hump has the Transfer case shifter hole and column is automatic. But were these TH350, similar to the blazers/trucks? Or was the 400 already in play in 1971, or Other? It appears to have the NP205 still in it.

Excited to get this thing going as I hunt for just about everything it needs. Which is, everything. ha!
