I am finalizing the parts choices on my engine swap. Working on a 1989 K5 Blazer 4x4 w/ 4.56 gears and 35s. Currently has a TBI 350/700R4 in it
I just snagged a Vortec 383 and have an older Edelbrock Vortec MPFI system and a Holley 670 throttle body.
I can either use my existing ECM and get someone to burn my ships and hope for the best or I may try to swap a harness and PCM out of a later vehicle like and Express van with a Vortec then I can learn my own programming.
I'd like to swap but am having a hard time finding a harness and PCM from a 0411 equipped van.
I did find a 494 and harness from a 2000 5.7 van
I could use another setup but want to be able to tune myself.
Recommendations?
