Hello,
I have a 93 LX 5.0 with a Edlebrock Perf. RPM II intake, a mild cam, gutted exhaust (H-pipe) and underdrive pulleys. Does anyone have a clue as to how much HP switching over to GT-40 heads would give me? I currently have the stock heads. Just curious as I have founds some for sale for cheap... THANKS!!!
