Similar here. 1974 502 5speed. Had the '69 tri power on it. It ran fine with that set up. I installed the sniper along with the tanks fuel tank. Only problem was line leaking on the fuel pump in the tank. Took a bit to isolate it but after I bought a pressure gauge and dropped the tank again it wasn't a bad fix. As far as performance, it really woke up the engine. Like driving a different car. I'm not very keen on the tuning part. Luckily my son has one on his Chevelle and helped me get it fine turned. As most will say they run better the more you drive them. I've since replaced the tired 502 and replaced it with a zz502 crate engine. Sometimes I wish I had a little less engine as it's an animal and I really can't beat on it and will definitely get my *** in trouble in a flash.
