Hi guys, I have a 1994 chevy k1500 with a Tbi 350/4l60e with the 16197427 ecu. Im looking to swap the tbi system for a holley 600 cfm classic carb system to lead up to my later project of a 5.3 lsx carb swap. Im hoping to keep the 4l60e and maybe tune the prom a bit to be able to use the stock distributor and computer timing to make my swap a little easier. I know its a bit oddball, but any help would be appreciated. Im new to tuning and am using tunerpro. If anyone has any ideas that will help me along with my carb swap, please let me know. Thanks in advance.
