I’ve got a 1997 chevy c1500 with a 350 sbc that I want to spray around a 150-175 shot in and I was wondering what my options for adjusting the timing are I’ve been looking around but most of the kits I’ve seen come with new distributors but they are not the flat top kind like the one I have as well they don’t have the sensor that plugs into the cap so I don’t know what to do about that. I’m just looking for some pointers on what direction I should go.

 

Swap to 0411 ecu then use efilive custom os with nitrous control

 

is there a certain brand/company you would recommend for the ecu and do I need to change any wiring?

0411 is the ecu used in the early ls1s. its a very easy swap, you just pull pins from the old connectors and plug them into the new connector, flash the ecu for a express van and go

 

And then I’ll use efilives software to progressive tune timing?
is there another way it would take a lot to swap it and I’ll have to pay someone to flash and tune it because I’ve got no clue where to start on that

 

the 97 vortec ecus are trash, the 0411s are not. if you are going to try to hack job it some other way, better have a spare motor. good luck.
