You can't expect big gains down low no matter what the cam. He asked what stock cam would work and still receive a bump in performance. It will still be better than stock which is what he asked.
Whats the compression of a stock LS1...10.5:1. The compression of a stock LM7...9.1:1.
It makes a difference. Thats why when you add more parts to the LS1 you will net larger gains across the board period. Sure adding the flat tops to the LM7 will help with the compression, but you still lack the displacement.

And yeah I know that its a budget build so why not save the money needed to do the cam swap and spend it on something more usefull like saving it to buy a maggie or gears.
