I have been running this intake for a couple of years now, painted the right shade of blue and with a stock aircleaner, it makes the engine look very nice and stock, and camouflages whatever aftermarket carb you are running. I switched out an Eddelbrock manifold. To be perfectly honest, I have a pretty stock engine, with iron heads, probably rebuilt in the '90s with 300 hp and I don't work it very hard, so given all that, I didn't expect any dramatic improvement and I can't say whether it gives any extra hp or torque. If I had a freshly rebuilt engine, with nice heads, cam, carb etc, I would expect to see some improvement from it. That said, the current engine runs well and does seem to have good torque. I bought mine personally from Scott, when I was back home a few years ago. Super nice guy and really seems to know what he is doing, and collaborates with other experts.
