In that case a Sum-2800-1 is the cam I would use+ it’s lift will work better with your stock valve springs.
You will of course need new lifters and timing chain and gears.
You will need to remove the radiator to get the old cam out and the new one in.
It will the help of a second person to guide the old cam out and the new one in without harming the cam bearings.

I was looking at the summit 2800, but I’m worried it won’t be worth the effort of swapping the cam. Like it’ll be too similar to the stock cam and won’t have much difference. While my main goal is to increase power I do want it to have a nice cammed idle sound. I know the 2802 is way too big for my set up, but figured the 2801 might be a good choice since it’s between the two. Unless I’m looking at it all wrong. What would the main difference be between the 2800 and the 2801? I know different lift and duration but I’m not sure what these differences really do. I talked to a summit tech, and he recommended me a set of comp springs 988-16. If I changed to these valve springs would the 2801 be a good choice?
