I will take some of the blame. Mistook this comment as coming from the OP. It did NOT.
"I want to find something that will wind up there and also have a very, very lumpy idle, crackely lumpy."

I am mostly guilty of going sideways on this thread. I do appreciate all the comments.

Back to the OP. Cheapest way to go would be the Elgin cam. ELGE904PMDL
Virtually identical to the LT-1 camshaft. You are going to be right on the edge of detonation. If you are planning to disassemble the short block anyway, and you want to have a little hedge against detonation, you could have .010 cut off the tops of the pistons. Would actually help turbulence a bit. You would want to have the rotating assy balanced, but I do that on every engine build. Cheap insurance. If you are wanting to go roller, call Chris Straub at Straub technologies. He is on the cutting edge of camshaft technology for old school SBC engines.

The GM off road cams are nice if you have lots of rear gear.
They are lumpy old school, No bottom end torque, goodness And VERY easy on valve springs !! I run a 140 with 1.7 rockers in my 72 nova 350 flat tops zero decked with 4.33 rear and fast burn heads. 11.60's @ 113. Definitely needs good fuel. I add a couple gallons of 100 LL to a tank of 91. Gary

Graeme, I have a very similar hydraulic roller on the shelf that I pulled out of a 406 years ago to swap in a solid roller. I think it's way too big to work in a 302, but I'm curious what you think, as I was strongly contemplating it myself.

I did ask about the off-road cams, not because they are lumpy. IIRC I started the thread with questions am I not allowed to ask others? with my LT1 I have a blank canvas and I ask because I am not a cam expert I don't want do this over because I grabbed what sounded cool so please give a guy with little experience a break would you?

Your posts are confusing?
You ask for advice on an LT-1 cam, then jump in saying hold up...nothing lumpy? Then you post again the next day asking about two camshafts known as the lumpiest of the DZ-302 profiles? Read that whatever way you want...

One further note since you took that whole suggestion out of context? If you call the guys at Comp's tech line...ask them exactly what will work best in a street-driven LT1 on pump gas.
You might hear some very similar advice to what you have already gotten. Out!
