I need some good advice!!!. I have the whole TPI setup from an 86 z-28 305. (ECM, harness, all sensors, intake plenum, runners, base, throttle body, etc.) The base will physically mount to my engine, mid 1970s 400 small block, 4 bolt main, bored .030" over to make a 406. Compression ratio is 10.2:1, 6" rods, Trick Flow Specialties Twisted Wedge heads, Kieth Black Hyper-eutectic pistons. Competition cams retrofit hyrdaulic roller. I have 36 lb/hour injectors and a 1000cfm throttle body. The questions that I am running into are; 1)will the stock runners, plunum and base flow enough air, 2)how do I recalibrate the computer to accomodate a new fuel map, 3)will the MAF flow enough air to satisfy this engine and 4)how will the low vaccuum that this engine produces affect the computer? Obviously I am started on this project, but need some help finishing it successfully. Anyone that can help out- please do. I did contact Lingenfelter Performance (they are only an hour from where I live) and they want to sell me the ACCEL SuperRam system, which would probably work, but also costs $3000. I already have a good bit sunk into this engine and can't see spending that kind of money that would just duplicate a lot of what I already have. Any help would be greatly appreciated. Thanks in advance, Luke
