i mounted injector bungs on a 45 angle within 1/4" of the head flange. i did use 6 injectors 42lbs each. two per intake hole and mounted inline with one common fuel rail. i am also using a modern gm throttle body from the ls series vthings. mine is from a 5.3liter vortec. it is a big mono blade with tps and iac, and is cable operated. i have extras if anyone needs one. i do need to make an adapter to mount it to the intake at a 90 degree angle pointed toward the fender. if anyone needs i did make a very nice jig for clamping the intake to a mill to machine the injector bungs. i could provide that service to anyones 250/292 intake. my goal is 400 hp and lots of fun with a stick.tom
