Don't order any cam until you absolutely verify which lifters you have.
The easiest way to do this would be to remove a valve cover and one pushrod. Count the turns as you loosen the rocker arm and retighten exactly the same amount will save needing to adjust that valve when you reinstall the pushrod. Stick a borescope down the hole and look at the lifters. You can get one for your phone on ebay for under $10.
You won't be able to see the bottom of the lifter but will be able to see if there are roller lifter retainers or not.
The tin spider and the figure 8 shaped retainers around the lifters will not be there with a flat tappet cam.

Call Summit and tell them what you are looking for. They have tech help for picking the right cam. And a lot of roller cam choices for under $500. Some around $200.
Ok I will definitely do that and I’m going to talk to comp cams tomorrow

You're going to have a blast when cold weather hits...Vortecs have no heat crossover and will make the engine cold natured until it's nice and warm. Make sure your choke is working and adjusted properly.

I've put a set of narrow body 1.6 ratio rockers on several mid 90 LT1's that add a little kick.I’ve read people running a LT1 cam in there 5.7’s so I looked and is this the cam they are talking about?

Methinks similar were OE on LT4's.
I live in North Carolina and have a daily so no worries there.
