LS2 bolt-ons to LS1
Vette: 853/241 heads, and LS1 intake
GTO: 243 heads, and ls6 or ls2 intake
Swapping it over, especially having P+P work done on the 243s could be worth some good hp. I would think you would need a cam to really make the heads/intake shine. Doesn't have to be a big cam though, could be as simple as a TR224 or TR228. I don't see why you couldn't pick up 30-40 from the cam, 15 from the intake and another 25 or so from the heads. Thats 70-80 hp
