new here ya'll.
I have a problem with my truck hope you can help with.
Like i said it is a 90 chevy 4x4, we built a new motor for it which runs great, it is a .30 over 350 roller motor with vortec heads, mild cam (power comes in about 1500 rpm) headers, we used a duel plane perfomer intake with a TBI adaptor plate to retain the TBI fuel sysytem, and a turbo 400 trans, it has a new fuel pump and filter also, timing is set perfect.
The problem I am having is from a dead stop it will not take off with out stumbling you must feather the gas pedal until about 1100- 1200 rpms then she kicks in and runs great, any heilp would be appreaited.
Thanks all
