I knew before hand that it wasnt the perfect combination for my setup. I only used this carb and intake setup because I already had them laying around as extra parts. Anything is better than the stock 2 barrel setup that was on it as that needed a complete rebuild. It was running so rich that your eyes would burn standing next to it and you could basically watch the gas gauge go down. The truck runs 100 times better than it did. The only problem is if I try to get on it quick it will bog down bad until I get moving. I just want to try to get this fine tuned for now until I get my 340 finished to put in it.
