Stock LT1 cam options

I get that. If you're willing to live with a mild lope then the hot cam and 1.6 rockers would give you want, I believe. I don't think that would do all the surging and bogging you're talking about. It's still mild - it just won't idle like stock anymore. OTOH, you could bump the idle 100-200rpm and probably not be able to tell the difference from stock. FWIW, a stock LT4 was pretty equal in power to an LS1, and I think the hot cam kit on stock LT1 heads would get you to that amount of power or maybe slightly more. So your goal is in reach if you don't actually need a completely stock-sounding idle.

I dont see 350 at the tires with just the cam, youll need more. You could always leave the small valves, a moderate port job and let the #s be what it may. That cam be done without much damage to the wallet or time if you DIY. Would have to pull out a file of flowsheets I dont recall stock LT1 heads anywhere near 220 but its been awhile.
Then it's like, might as well re-ring it, oh the bore is out of round, might as well bore it. Next thing I know it's a race car.

True, I could just do an 800rpm target idle to get some vac back at idle and smooth out the cam.
I also need to figure out where the damn oil leak is. The whole front of the block is covered in oil. I did the intake last year, it's not that. I sprayed about 12 cans of break cleaner on the front of the block when I did the water pump + opti, and it's all wet again.

Have you seen this thread? Custom Lunati cam which appears to combine the Bootlegger intake lobe with a milder exhaust lobe on 110 lsa IIRC.

Have you considered the cc503 in your LT1? That's what I have in my MR L98 and it makes the power you're looking for. You seem to be pretty knowledgeable but trying to find a 50+ hp cam for an otherwise stock engine without changing idle quality?.... C'mon man.
