Hes the back story, gentlemen, my k10 is getting swapped over from diesel to gas. A 400 to be exact. Its a 2 barrel now and I would like to change that. I was looking over my Jegs catalog and found what I think looks like a decent intake, it is an Edelbrock Performer. Here is the discription. - Dual-plane, low-rise intake manifolds thats feature a 180 degree firing order and a patented runner desgin that you wont find on other brands. This patented design greatly improves torque and horsepower over a wide rpm range and makes it especially explosive from off-idle to 5500 RPM. Throttle response is excellent. Performers are idel for daily drivers, street machines, street rods, trucks, 4x4s, tow vehicles and rvs. Most are 50 state legal when used with the correct carb and in correct applications. The particular model im looking at is for a SB-Chevy 400, non-egr now manifold only is 114.99, manifold and install kit is 142.99, then you can get cam and lifters for 139.99 Does this seems like a good deal? My truck will be lifted eventually, used for work around the farm, towing, and daily driving. Now for carburetor ive heard many different things. That edelbrocks are easy to tune, but they suck offroad even with needle sets. I was told tonight that quadrajets are better then edelbrocks. I would like to sort through some of this, here is the Edelbrock im looking at in jegs. 650 CFM Thunder Series AVS, Offroad with manual choke 345.99 - these share all the performance advantages of the performer serious with innovative new features, quik tune secondary air valve can be easily adjusted to match your needs, with you want the secondaries to kick in early or late. you can set the air vavle using standard tools. with no extra springs. Its a quick and simple process. qwik tune combined with other great features make this the most conveient and dependable carb available today. for 4x4 owners the thunder series avs offroad carbs include spring-loaded needles and seats for outstanding performance in rough uneven terrain. Then for this carb there is a calibration kit for 49.99 would i need this? Also a Dual Feet fuel line design especally for the avs. Two include an aluminum fuel filter for 81.99 Does this seem like a good carb, if not what would you recomend. Also Kert if you read this could you talk to Terry if he thinks that intake would work good on my motor. Edit: also guys im planning on running true duals with no cats for sure and most likley hollowed out glass packs or nothing at all(yes i know im going for menace to society hehe) I didnt know if that would impact the intake answers or not, Im also not sure about headers or manifolds yet.
